Product details

Active production — 75 V, 200 mA small-signal switching diode

The 1N4148UR-1 is a general-purpose switching diode from Microchip Technology, rated 75 V reverse voltage and 200 mA average rectified current — the standard 1N4148 electrical specification in a hermetic DO-213AA surface-mount package. Reverse recovery time is 20 ns, fast enough for high-speed switching in logic-level and signal-conditioning circuits where the 1N4148 family has been the default choice for decades.

DO-213AA hermetic package — surface-mount reliability for harsh environments

The DO-213AA (MELF-style) package is a hermetic glass body with metallized end caps, designed for direct solder attachment to the PCB pad — no leads to fatigue under thermal cycling. Forward voltage is 1.2 V max at 100 mA forward current; reverse leakage is 500 nA max at 75 V — both within the standard 1N4148 parametric limits.

Active production — sourcing through authorized channels

RoHS compliance is not claimed — this part is marked RoHS non-compliant, which is typical for hermetic military/aerospace diodes that use lead-based solder finishes.

Frequently asked questions

What is the 1N4148UR-1 reverse recovery time?

The reverse recovery time (trr) is 20 ns, making it suitable for high-speed switching applications up to tens of megahertz.

What package is the 1N4148UR-1 in?

It comes in a DO-213AA hermetic surface-mount package, also referred to as MELF (Metal Electrode Leadless Face).

Is the 1N4148UR-1 RoHS compliant?

No, Microchip Technology marks this part as RoHS non-compliant, typical for hermetic military-grade diodes with lead-based solder terminations.
