That 118 V clamp is the hard limit — any transient that drives the rail above 118 V will be shunted through the device. ## Automotive-grade screening and package fit AEC-Q101 qualification and the Automotive grade designation mean this part has passed the temperature cycling, high-temperature reverse bias, and ESD reliability tests required for under-hood and chassis-mounted electronics. The DO-201AA (DO-27) axial-lead package is a through-hole footprint that fits standard PCB layouts and terminal-block assemblies. The bidirectional channel protects both positive and negative transients on a single signal or power rail — no need for two series diodes to handle polarity reversal. ## Active lifecycle — no EOL clock ticking No stock-holding claim — the supply posture is quoted to order.","metaTitle":"1.5KE82CH Taiwan Semiconductor Zener TVS, 1500W","metaDescription":"1.5KE82CH bidirectional Zener TVS diode, 1500W peak pulse, 66.4V standoff, AEC-Q101 Automotive grade.
