The three ratings that define protection fit are the reverse standoff (the working voltage the line sits at undisturbed), the breakdown threshold, and the clamping ceiling under peak pulse current. A 9.4 V reverse standoff means the diode stays off and draws only leakage current while the protected line operates at or below that voltage. This rating — combined with the 96.2 A peak pulse current — tells you it survives Class 2 or moderate Class 3 surge levels per IEC 61000-4-5 without cascading an upstream fuse or input stage. ## High-temperature junction and thermal margin The DO-201AA (also called DO-27) axial package is the standard through-hole outline for 1.5 kW TVS diodes. Leads are soldered directly to PCB holes — no surface-mount reflow profile. The Tape & Box packaging variant /73 ships on a taped reel with a box, common for automated insertion in production runs. ## TransZorb® series — single-channel unidirectional protection The TransZorb® series is Vishay's internal brand for its Zener-based TVS construction. This part is unidirectional (one direction clamps positive transients) — for bidirectional protection across AC lines or differential signaling, look for the Vishay part variant with a 'C' suffix instead (1N6272CA).","metaTitle":"1N6272A-E3/73 TVS Diode, 1.5kW, 10.5V Zener","metaDescription":"Vishay 1N6272A-E3/73, 1.5kW peak-pulse TransZorb® TVS diode, DO-201AA axial. 10.5V breakdown, 9.4V standoff, 15.6V clamping.
