1N6271A-E3/54 Description

Short technical summary and product information.

The 1N6271A-E3/54 is a 1500W unidirectional transient voltage suppressor diode from Vishay General Semiconductor, part of the TRANSZORB series. It is designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning.

 

This device features an 8.55V reverse stand-off voltage and a clamping voltage of 14.5V at a peak pulse current of 103A. It uses Zener technology with a glass passivated chip junction for reliable performance. The diode offers a peak pulse power rating of 1500W with a 10/1000μs waveform and a very fast response time.

 

The 1N6271A-E3/54 is housed in a DO-201AA (DO-27) axial package with matte tin plated leads for through-hole mounting. It operates over a junction temperature range of -55°C to 175°C and has a power dissipation of 6.5W. The device is RoHS3 compliant and the molding compound meets UL 94 V-0 flammability rating.
