The 1N5811US is a high-reliability ultrafast recovery rectifier diode from Microchip Technology, designed for demanding applications. It features a working peak reverse voltage of 150V and an average rectified current of 3A. The device offers a fast reverse recovery time of 30ns and a low forward voltage drop of 875mV at 4A, making it suitable for high-frequency switching circuits.
This diode is hermetically sealed in a void-less glass SQ-MELF package (B case) with surface mount mounting. It has a junction operating temperature range of -65°C to 175°C and a forward surge current capability of 125A. Thermal resistance is specified at 6.5°C/W junction-to-end cap and 52°C/W junction-to-ambient.
Typical applications include switching power supplies, military and aerospace electronics, and other high-reliability systems requiring fast switching and low forward losses. The part is available in commercial and military (JAN, JANTX, JANTXV, JANS) grades per MIL-PRF-19500/477.
The maximum working peak reverse voltage (Vr) is 150V.
The average rectified current (Io) is 3A.
The maximum forward voltage (Vf) is 875mV at 4A.
The reverse recovery time (trr) is 30ns.
It comes in a surface mount SQ-MELF, B package (also known as B, SQ-MELF).
The junction operating temperature range is -65°C to 175°C.
The forward surge current (Ifsm) is 125A.
