The clamping voltage is 45.7 V maximum at the rated 32.8 A peak pulse current (10/1000 µs waveform), which sets the voltage the downstream circuitry must survive. For a 28 V bus, that 45.7 V clamp gives a 17.5 V margin above the rail — enough headroom for most 60 V-rated downstream FETs and controllers. ## Automotive temp range and package fit The AEC-Q101 qualification means the part has passed the reliability stress tests (HTRB, H3TRB, temperature cycling) required for tier-1 automotive programs. The DO-201AA / DO-27 axial leaded package is a through-hole form factor that suits point-to-point wiring on terminal strips or PCB mounting with 0.375-inch lead spacing. The 1.5KE body size is the standard footprint for this power class — replacement in an existing BOM is a direct drop-in for any 1.5KE-series part in the same package.","metaTitle":"1.5KE33AHE3_A/D Vishay TVS, 1500W, 28.2V Standoff, AEC-Q101","metaDescription":"Vishay 1.5KE33AHE3_A/D 1500W Zener TVS diode, 28.2V reverse standoff, 45.7V clamp, AEC-Q101.
