The 24.4V minimum breakdown is where the Zener characteristic begins to turn on; the diode stays off below it. The 1500W peak pulse rating (1.5kW) is the surge energy the part can absorb once on that waveform — it is the selection ceiling, not a continuous rating. A 12V automotive rail protected by this diode survives ISO 7637-2 pulse severity 3a/3b transients when the peak energy stays within that 1.5kW envelope. ## DO-214AB package and automotive thermal envelope The DO-214AB (SMC) is the standard 2-pin surface-mount package for this power class — no exotic footprint risk, compatible with standard pick-and-place and lead-free reflow profiles. The SMC lands on a standard pad layout used across multiple TVS suppliers, so second-sourcing is straightforward on the board. Rated junction temperature runs -50°C to 150°C — the upper bound covers the engine-bay ambient swing and the self-heating from surge dissipation. Automotive deployment means the board-level thermal path and the diode's own RthJC matter: keep the case temperature below 150°C during surge events to stay within the rated junction limit.","metaTitle":"1.5SMCJ22CA-AQ Zener TVS Diode, 22V, 1500W","metaDescription":"Diotec 1.5SMCJ22CA-AQ bidirectional Zener TVS diode, 22V standoff, 35.5V clamping, 1500W peak pulse, DO-214AB.
