1N6391 Description

Short technical summary and product information.

The 1N6391 is a Schottky barrier rectifier diode from Microchip Technology, designed for high-reliability applications requiring low forward voltage drop and fast switching. It is rated for a maximum repetitive reverse voltage of 45V and an average rectified forward current of 25A at a case temperature of +25°C. The forward voltage is typically 500mV at 5A forward current.

 

This diode offers a high surge current capability of 600A (8.3ms half-sine wave) and a junction operating temperature range of -55°C to +175°C. The thermal resistance from junction to case is 2.0°C/W. It is packaged in a hermetically sealed DO-203AA (DO-4) stud mount package with a 10-32 threaded stud and cathode-to-stud polarity.

 

The 1N6391 is suitable for use in freewheeling diodes, rectification in high-frequency low-voltage inverters, and polarity protection circuits. Military grade versions (JAN, JANTX, JANTXV, JANS) qualified per MIL-PRF-19500/553 are available.
