Clamping envelope for a 66.4 V rail
The 1.5KE82CH: Its 66.4 V reverse standoff voltage means the protected rail can run at 66.4 V DC nominal without the TVS conducting leakage; the breakdown threshold starts at 73.8 V min, and the clamping ceiling is 118 V at the 13 A peak pulse current. 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.
