A single unidirectional channel, so the diode conducts only on positive overvoltage relative to ground. For a DC rail that never reverses polarity, this is the standard fit; for an AC signal or a bidirectional bus, a pair back-to-back or a dedicated bidirectional part is needed. ## Breakdown and clamp — the numbers that decide fit The minimum breakdown voltage is 40 V, meaning the diode starts conducting leakage current well before the 58.1 V clamp is reached. This gives a guard band: a 36 V supply rail that holds regulation at 38 V during a transient still sits below the breakdown threshold, so the TVS stays off until the transient pushes past 40 V. Rated for continuous operation from -55°C to 150°C junction temperature. That covers the full industrial temperature envelope and extends into automotive under-hood environments — the 150°C ceiling means the diode does not derate its clamping performance when mounted near a hot power stage or inside a sealed enclosure. ## Active production — no last-time-buy pressure Diodes Incorporated lists the SMAJ36A-13-F as Active. If a higher or lower standoff voltage is needed for a different rail, the same PCB layout accepts the sibling order codes in the SMAJ series without a board spin.","metaTitle":"SMAJ36A-13-F Diodes Inc TVS Diode, 400W, 36V Standoff, SMA","metaDescription":"SMAJ36A-13-F TVS Zener diode, 400W peak pulse power, 36V reverse standoff, 58.1V clamp.
