The junction temperature range spans -55°C to 150°C, covering industrial equipment operating in unconditioned enclosures and automotive under-hood environments where ambient heat plus self-heating from repeated surges must stay within the die rating. The base product number SMAJ51 anchors the family; the -13-F suffix denotes the reel packaging variant and RoHS compliance. ## Active production — no obsolescence risk for new designs For a protection diode, lifecycle continuity matters — a TVS that goes NRND forces a requalification of the clamping voltage and surge energy on every protected rail. This part's active status removes that risk from the BOM.","metaTitle":"SMAJ51CA-13-F Diodes Inc TVS Diode, 400W, 51V, DO-214AC","metaDescription":"SMAJ51CA-13-F bidirectional Zener TVS, 400W peak pulse power, 51V reverse standoff, 82.4V clamping.
