This means a 24V rail or a 26V signal line sees the TVS start conducting at 28.9V and holds the line below 42.1V during a surge — adequate for protecting downstream ICs rated to 40V or higher. ## 400W peak pulse — what it covers This power class handles typical ESD transients, inductive load dumps, and short-duration surges on low-power supply rails or I/O lines. For longer-duration faults or higher-energy surges, a larger package or higher power rating would be needed. ## DO-214AC SMA — board-fit note Housed in the standard DO-214AC (SMA) surface-mount package, with a supplier device package designation of SMA. The footprint is shared across many TVS diodes and Schottky rectifiers — a replacement in the same package family should fit the existing PCB land pattern without a board spin. ## Temperature range and channel count Single bidirectional channel — one device protects both polarities on a single line, saving board space compared to back-to-back unidirectional diodes.","metaTitle":"SMAJ26CA-13 Diodes Inc TVS, 26V Bidirectional, DO-214AC","metaDescription":"SMAJ26CA-13 bidirectional TVS diode, 26V reverse standoff, 42.1V clamp, 400W peak pulse.
