Peak pulse current is 86.7 A under the same 10/1000 µs condition — the device absorbs that current while holding the clamp voltage. The reverse standoff voltage (working voltage) is 9.72 V typical, so it stays out of conduction below that level and only activates when the transient exceeds the breakdown threshold of 10.8 V min. ## Bidirectional single-channel in DO-201AA axial A single bidirectional channel — one device protects both polarities on the same line, simplifying the BOM count for AC-coupled or bipolar signal rails. The DO-201AA (DO-27) axial-lead package mounts through-hole, which is a legacy footprint still common in high-reliability and high-vibration assemblies where a soldered lead is preferred over a surface-mount joint.","metaTitle":"Vishay 1.5KE12CHE3/54 TVS, 1500W, 17.3V Clamp, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE12CHE3/54 automotive TVS diode, 1500W peak pulse, 17.3V clamp, AEC-Q101.
