Supply Chain & Allocation Reality:

These two SOT-23 MOSFETs are the level shifters and small switches of modern boards: the standard parts behind I2C bus translation, 3.3V-to-5V interfacing, small load switching and a hundred interfaces that needed something better than a resistor. The pair reads as one drawer and is not one part: the classic 2N7002 is the 60V general switcher whose threshold spec assumed a real gate drive, while the BSS138 is the low-threshold original marketed precisely for 1.8V and 3.3V logic. The variants blur the line constantly - the 2N7002K generation moved thresholds down toward BSS138 territory, and the BSS138K moved voltage up toward 60V - which is exactly why the substitution discipline here is reading the threshold margin and the on-resistance at the actual gate voltage, not the family glance.

The Level-Shifter Standard

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The low-threshold standard: 50V class, gate threshold typically under 1.5V maximum, on-resistance around 1.6-3.5 ohms at 5-10V gate - the part the classic bidirectional I2C level shifter circuit is drawn around.

50V class (60V in the K variant); 200-280mA class current.

Compatibility & Drop-In Notes: At 1.8V and 2.5V logic the threshold margin is the design; the classic 2N7002 needed a wider drive and is the weaker choice there. In the shifter, verify the body-diode orientation and the gate rail - the circuit self-directs only when wired as the standard figure shows.

The Improved Threshold Generation

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The modern 2N7002 die: 60V rating with the threshold lowered (about 1.1-1.3V typical) toward BSS138 territory - documented by several sources as a functional substitute for the BSS138 in level-shifter duty.

60V class - the voltage advantage over the plain BSS138.

Compatibility & Drop-In Notes: This is the substitution that actually works in both directions for level shifting: 2N7002K-class dies at BSS138 positions (with the 60V bonus), and BSS138 at 2N7002K positions where the resistor network was sized for its curves. Read the K.

The Through-Hole Sibling

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The TO-92 version of the 2N7002 design: same small-signal N-channel idea in the legacy through-hole body - the repair-shelf part for boards that predate SMD.

60V class; the same modest current envelope.

Compatibility & Drop-In Notes: Package swap, not just a body: the TO-92 part serves through-hole repair and breadboards; the SOT-23 parts serve the boards being repaired today. Same circuit role, different worlds.
Package & Solder Footprint: TO-92 against SOT-23: different footprints and different pin orders.

The Power Tier Next Door

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

The power-tier neighbor: a SOT-23 MOSFET built for actual current (30V class, several amps with a couple of tens of milliohms) - what the 2N7002 family becomes when a small load needs real switching.

30V class - a different voltage world from the 50-60V small-signal pair.

Compatibility & Drop-In Notes: Substituting up the tiers is a gift (gate charge still tiny); substituting down is the classic smoke - a 2N7002 standing in for an AO3400-class part drives the load through a heater. Match the tier to the current.
Package & Solder Footprint: SOT-23 with its own pin map per maker - verify before layout.

Buyer & Quality Checklist for Sourcing Alternatives
  • The threshold margin is the whole selection: the classic 2N7002 (max threshold near 2.5V) wants a real gate drive; BSS138 (max about 1.5V) and the K-suffix generations exist for 1.8V/3.3V logic. Read VGS(th) AND the on-resistance at the actual gate voltage - the headline Rds numbers are at 5-10V.
  • The K suffixes modernized both rows (2N7002K, BSS138K): the letters now matter more than the family names in level-shifter and switch substitutions.
  • SOT-23 MOSFET pinouts are maker drawings, not a standard: the same body hosts G/S/D in different orders across the industry - the schematic symbol orientation does not protect the placement machine.
  • The bidirectional level shifter depends on the body diode: wiring it gate-to-low-rail with pull-ups on both sides works in both directions only when the orientation is right. A reversed part looks assembled and blocks one direction.
  • Current is small-signal: 200-300mA class at these Rds - driving relays or lamps directly is the AO3400 tier question, not this pair.
  • At bus speeds, the level-shifter limits are the pull-up values and the capacitance: a shifter that works at 100kHz and fails at 400kHz is a resistor arithmetic problem, not a transistor one.
Frequently Asked Technical Questions

Q: Can BSS138 and 2N7002 replace each other?

A: Direction matters: BSS138 (and 2N7002K-class parts) drive from low-voltage logic where the classic 2N7002 threshold leaves no margin; a plain 2N7002 in a 1.8V shifter is the substitution that half-works. Also compare the 50V/60V ratings and the Rds at the actual gate voltage.

Q: Why do I2C level shifters use BSS138?

A: Low threshold plus symmetric pull-ups: the part stays fully enhanced from the 1.8V or 3.3V rail and its body diode provides the second direction. The circuit is two resistors and one BSS138 per line - the standard figure works because the threshold suits the low rail.

Q: Is 2N7000 the same as 2N7002?

A: The same design in different bodies: 2N7000 is TO-92 through-hole, 2N7002 is SOT-23 - and their pin orders differ. Same circuit role, different footprints and assembly worlds.

Technical Details & Description

What this small-signal MOSFET does on your board

The 2N7002H6327XTSA2: Infineon OptiMOS N-Channel MOSFET, 60 V drain-source, 300 mA continuous drain, SOT-23-3 package.

60 V Vdss and 300 mA Id — the voltage and current ceiling

The 60 V drain-source rating gives comfortable headroom for 12 V and 24 V industrial buses, automotive battery lines, and 48 V telecom rails. Derate for temperature: at 85°C ambient the current capability drops roughly linearly, so budget 200 mA or less for reliable operation in a warm enclosure.

3 Ohm Rds(on) and 0.6 nC gate charge — what they mean for drive and heat

Maximum on-resistance is 3 Ohm at 500 mA with 10 V gate drive. Gate charge is 0.6 nC at 10 V.

Supplier device package is PG-SOT23.

Frequently asked questions

Is 2N7002H6327XTSA2 a direct replacement for 2N7002?

Yes, the base product number 2N7002 confirms it is the same die function as the industry-standard 2N7002. The H6327 suffix denotes Infineon's specific tape-and-reel packaging variant. Pin-compatible with any SOT-23 2N7002 from other manufacturers.

What is the closest pin-compatible alternative to 2N7002H6327XTSA2?

Any standard SOT-23 2N7002 from ON Semiconductor, NXP, or Diodes Inc is pin-compatible and functionally equivalent. The Infineon OptiMOS variant offers the same 60 V / 300 mA rating with a slightly lower typical Rds(on) than some generic 2N7002 parts.
