The supplier device package is SMA — standard for this power class. The junction temperature range spans -55°C to 150°C, so it handles industrial ambient conditions without derating concerns on a typical 85°C PCB. Lifecycle status is Active per Diodes Incorporated. No NRND or EOL flags. The base product number SMAJ12 covers the family; the -13 suffix indicates tape-and-reel packaging. Cut Tape (CT) option also listed for prototype or low-volume builds.","metaTitle":"SMAJ12CA-13 TVS Diode, Diodes Inc, 400W, 12V Standoff, SMA","metaDescription":"Active SMAJ12CA-13 bidirectional TVS from Diodes Inc. 400W peak pulse, 12V reverse standoff, 19.9V clamp at 20.1A.
