The 1500W rating applies to the 10/1000µs test waveform; for shorter pulses (like 8/20µs from ESD or lightning), the peak power capability is higher, but the datasheet's derating curve governs the safe operating area at elevated temperatures. ## Through-hole axial package — board-fit note for rework Housed in a DO-201AA (DO-27) axial-lead package, it mounts through-hole. The 1.5KE footprint is standard across the series — same hole pattern as other 1.5KE parts, so swapping voltage grades on the same board layout is straightforward. ## General-purpose surge suppression — no power-line rating Vishay lists this part for General Purpose applications, and the spec explicitly states Power Line Protection: No. That means it is designed for signal and low-voltage DC rail protection (12V buses, sensor supplies, I/O lines), not for AC mains or high-energy power distribution. The 10.2V standoff suits 12V nominal systems where the rail stays below 10.2V in steady state.","metaTitle":"1.5KE12CA-E3/73 TVS Diode, 1500W, 10.2V, DO-201AA","metaDescription":"Vishay 1.5KE12CA-E3/73 TransZorb bidirectional TVS, 1500W peak pulse, 10.2V standoff, 16.7V clamp.
