The DO-214AC (SMA) surface-mount package is a widely used footprint for board-level transient suppression, making this a drop-in fit for existing layouts that already use the SMA outline. Rated for operation from -55°C to 150°C junction temperature, the SMAJ70A-13 covers the full industrial temperature band and extends into automotive under-hood environments where ambient temperatures can reach 125°C. The 150°C TJ max provides margin for self-heating during repetitive surge events.","metaTitle":"SMAJ70A-13 Diodes Inc TVS, 70V Standoff, 400W, DO-214AC","metaDescription":"SMAJ70A-13 Diodes Incorporated 400W Zener TVS diode, 70V reverse standoff, 113V clamp, DO-214AC SMA.
