Product details

Active AEC-Q101 TVS for 77.8V rail clamping

The 1.5KE91AHB0G is an active-production Zener TVS diode from Taiwan Semiconductor, qualified to AEC-Q101 for automotive-grade reliability.

Automotive qualification and wide temperature range

AEC-Q101 qualification covers the -55°C to 175°C operating junction temperature range — suitable for under-hood or transmission-control modules where ambient heat soaks above 125°C. The device is not rated for power line protection; it is a unidirectional Zener clamp for signal or low-power supply rails.
