The TransZorb® series designation means the clamping element is the Zener junction itself — it absorbs the surge energy and clamps the overvoltage in one shot, rather than crow-barring into a hard short. This makes it a common choice on power rails ahead of sensitive ICs in engine-control units, instrument clusters, and other 12 V automotive boards where load-dump transients are a known hazard. ## What the clamping specs mean for the protection window The reverse standoff voltage of 20.5 V sets the normal working rail — the TVS stays off and draws only leakage current while the bus sits below this threshold. In a 14 V automotive system, a load-dump spike that drives the rail above 22.8 V triggers the clamp and holds the downstream circuitry at or below 33.2 V — that 10 V headroom between standoff and clamp is the design margin the protection engineer sizes the catch diode against. This is the ISO 7637-2 pulse 5 (load dump) test shape, so the rating maps directly to the automotive transient immunity test the ECU must survive. Switching the waveform to a faster 8/20 µs surge reduces the allowable peak current — the energy in the pulse is lower, so the device can survive a higher peak amperes, but the voltage overshoot during the rise time becomes the concern. ## Junction temperature and the automotive thermal envelope In an engine bay module, board-level temperatures routinely reach 125°C ambient at the ECU housing — the Zener dissipating even a few hundred milliwatts of clamp energy will self-heat above that ambient, and the 175°C junction limit gives headroom for short transient spikes without the part entering thermal runaway. The DO-201AA axial leadframe also acts as the primary thermal path to the board pad, so the land pattern and solder joint quality directly affect the thermal resistance the datasheet specifies. ## Tape & Box packaging — through-hole assembly note Supplied in Tape & Box (TB) — a straight-lead axial format, not a gull-wing or BGA. The DO-201AA body sits on a 3.5 mm lead pitch, which is wider than most bypass caps and resistors on the same board and allows hand-solder or wave-solder mounting without tight coplanarity concerns. The through-hole mount also means the device can be supported by its leads on both sides of the board — useful in vibration-heavy underhood applications where a surface-mount body is at risk of cracking on thermal cycling.","metaTitle":"Vishay 1N6280AHE3_A/D Zener TVS, 33.2V clamp, 1.5kW peak","metaDescription":"Vishay 1N6280AHE3_A/D unidirectional Zener TVS, 20.5V standoff, 33.2V clamping, 1.5kW peak pulse, AEC-Q101, DO-201AA axial.
