That 500W rating in a DO-214AC (SMA) package means it can absorb a 21A surge without failing, making it a solid choice for clamping transients on 12V or 13V rails in industrial and automotive environments. ## 13V standoff, 14.4V breakdown, 23.8V clamp The reverse standoff voltage is 13V — the rail voltage it leaves alone during normal operation. Breakdown starts at 14.4V minimum, and the clamping voltage peaks at 23.8V at the rated 21A peak pulse current. That 9.4V window between standoff and clamp is tight enough to protect downstream silicon without nuisance triggering on supply ripple. ## Active production, surface-mount DO-214AC The tape-and-reel suffix /TR13 indicates it ships on a 13-inch reel, typical for automated pick-and-place. ## Bidirectional, general-purpose protection","metaTitle":"SMAJ13CE3/TR13 – Microchip 500W Zener TVS, 13V Standoff","metaDescription":"Microchip SMAJ13CE3/TR13 Zener TVS diode: 500W peak pulse power, 13V reverse standoff, 14.4V breakdown, 23.8V clamp.
