AEC-Q101 bidirectional TVS, 1500 W, DO-201AA axial
The Vishay 1.5KE220CAHE3_A/C is a bidirectional Zener-type transient voltage suppressor from the Automotive TransZorb® series, qualified to AEC-Q101 for use in automotive electronics. The 185 V reverse standoff voltage and 209 V minimum breakdown voltage place it on a 150 V to 180 V nominal rail — suitable for suppressing load-dump and inductive kickback in 24 V automotive systems or high-voltage DC buses in hybrid/electric vehicle auxiliary circuits.
Package and thermal integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE220CAHE3_A/C mounts through-hole. The junction temperature range spans -55 °C to 175 °C, covering the full automotive under-hood and engine-compartment thermal profile without derating at the high end.
