The MSC 1N3891 is a high-reliability fast recovery rectifier diode, qualified per MIL-PRF-19500/304. It features a wide operating junction temperature range from -65°C to 175°C and a storage temperature range also from -65°C to 175°C.
Key electrical specifications include a peak working reverse voltage of 200V and an average forward current rating of 20A at 100°C case temperature. The diode exhibits a fast reverse recovery time of 150ns under specific test conditions (VRM = 30V, IF = 1A, TC = 55°C).
This rectifier is housed in a DO-203AA (DO-4) package, suitable for through-hole mounting. Its robust construction and high-reliability qualification make it suitable for demanding applications.
Absolute maximum ratings include a peak surge forward current of 175A for a 8.3ms half-sinewave pulse at 100°C case temperature. The thermal resistance from junction to case is a low 1.5°C/W, aiding in thermal management.
