The 26V reverse standoff gives roughly 4.3× margin over a nominal 24V rail, so the TVS stays inactive during normal operation and activates only on the transient. ## DO-214AB SMC footprint and what it demands of the board The DO-214AB (SMC) is the standard high-power TVS package at this rating class. ## One-directional clamping — know your polarity The 1.5SMCJ26CA is a unidirectional TVS Zener — it clamps positive transients on a single polarity. A bidirectional TVS in the same series carries a CA suffix; the bare CA suffix here confirms one-direction protection only. For AC rails or polarity-reversing circuits a bidirectional variant is required.","metaTitle":"Diotec 1.5SMCJ26CA, 1500W TVS Zener, DO-214AB","metaDescription":"Diotec 1.5SMCJ26CA unidirectional TVS Zener, 26V standoff, 42.1V clamp, 1500W peak pulse in DO-214AB SMC.
