Product details

What this STripFET N-channel MOSFET delivers

Housed in a surface-mount DPAK (TO-252) package, it suits automated assembly for medium-power boards.

The 30 V drain-source voltage rating sets the maximum rail this MOSFET can block; typical applications include 12 V and 24 V DC buses with headroom for transients. Gate charge of 27 nC at 5 V means the driver needs modest energy per switching cycle — suitable for PWM frequencies in the tens of kilohertz without excessive gate-drive losses. Input capacitance of 2060 pF at 25 V drain-source influences switching speed; a gate resistor may be needed to control ringing. The drive voltage range of 5 V to 10 V allows logic-level gate drive at 5 V, though the lowest Rds(on) is achieved at 10 V.

For existing BOM lines, procurement must rely on the surplus and broker channel to source remaining inventory.

Frequently asked questions

What is the replacement for STD100N03LT4?

No official replacement order code is recorded for the STD100N03LT4. For a pin-compatible alternative in the same DPAK package, look for a 30 V N-channel MOSFET with similar Rds(on) and current rating from ST's STripFET family or other manufacturers — verify the gate drive and thermal specs against your design.
