The 81V reverse standoff voltage means it clamps a nominal 24V or 48V automotive rail that sees transients up to 144V, absorbing 10.4A of peak pulse current (10/1000µs waveform). The 90V minimum breakdown voltage ensures the device stays off during normal operation but fires before the downstream silicon sees damaging overvoltage. ## Sourcing picture for an obsolete part This means the sole sourcing channel is the independent surplus and broker market, where lots are confirmed per RFQ with full traceability. Because the TransZorb series is mature and widely cloned, a pin-compatible alternative from the same DO-201 package family may exist, but no direct Vishay cross-reference is published. A parametric match requires checking the standoff voltage (81V), breakdown range (90V min), and clamping voltage (144V max) against any candidate.","metaTitle":"Vishay 1.5KE100HE3/73 TVS Diode, AEC-Q101, 1500W, DO-201","metaDescription":"Vishay 1.5KE100HE3/73 Zener TVS, 1500W peak pulse, AEC-Q101.
