Rated for 500 W peak pulse power on a 10/1000 µs waveform, it handles a peak pulse current of 12.8 A. That 500 W rating is a power-time product — at a shorter pulse (8/20 µs) the peak current capability is higher, but the 10/1000 µs figure is the standard comparison baseline across TVS families. ## Package and mounting — DO-214AC (SMA) on tape Housed in a DO-214AC (SMA) package, this is a standard surface-mount footprint shared across the SMAJ series. Supplied on Tape & Reel (TR), it feeds directly into pick-and-place without a reel change. The operating temperature range of -65°C to 150°C (TJ) covers military-temperature applications — cold-soak at -55°C is inside the envelope, and the 150°C junction limit allows derating headroom above 85°C ambient if the board layout pulls heat away from the package.","metaTitle":"SMAJ24CAE3/TR13 TVS Diode – Microchip, 24V Bidirectional","metaDescription":"SMAJ24CAE3/TR13 bidirectional TVS, 24V reverse standoff, 38.9V clamp, 500W peak pulse.
