1N6121AUS Description

Short technical summary and product information.

The 1N6121AUS is a bidirectional transient voltage suppressor (TVS) diode from Microchip Technology, part of the 1N6103AUS-1N6137AUS series. It is designed to protect sensitive circuits from transient overvoltages with a peak pulse power rating of 500W for a 10/1000 µs pulse. The device features a working peak reverse voltage (VWM) of 32.7V and a clamping voltage of 59.1V at a peak pulse current of 8.5A. The bidirectional channel allows for protection in both polarities. The Zener technology provides fast response. This TVS diode is built with voidless hermetically sealed glass construction and internal Category 1 metallurgical bonds, making it suitable for high-reliability applications. It is qualified to MIL-PRF-19500/516 and is available in military grades JAN, JANTX, and JANTXV. The surface mount package is SQ-MELF (B). The operating temperature range is -55°C to 175°C. Applications include military and other high-reliability systems requiring robust transient protection.
