The -55 °C to 175 °C junction temperature range is the thermal headroom that makes it viable in engine-bay and direct-chassis locations where ambient routinely hits 125 °C — the die still has margin at that temperature before the clamping voltage drifts. ## DO-201AA through-hole — board integration context Axial DO-201AA package, through-hole mount — the lead diameter and body length dominate the thermal path to the PCB copper. On a typical ceramic or FR4 board with a decent landing pad, the RthJA lands around 40–50 °C/W, which is why the 175 °C junction limit and the 1500 W surge rating need to be evaluated together under actual mounting conditions, not just the datasheet nominal.","metaTitle":"Vishay 1N6275HE3/54 Zener TVS Diode, 1.5kW, 22V Clamp","metaDescription":"Obsolete Vishay 1N6275HE3/54 Zener TVS, AEC-Q101 TransZorb, 12.1V standoff, 22V clamp, 68.2A peak pulse, DO-201AA.

The 22 V maximum clamping voltage is where the part clips a surge, so it protects downstream loads against load-dump spikes that exceed 22 V without letting the rail float up to the supply's overvoltage limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1N6275HE3-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1N6275HE3-54 when reusing this data.
