Bidirectional Zener TVS in a DO-214AB SMC Package
The SMCJ7.5CAE3/TR13 is a single-channel bidirectional Zener TVS diode from Microchip Technology, rated for 1500W peak pulse power at 10/1000µs waveform. It clamps transients at 12.9V maximum with a 116.3A peak pulse current capability, making it suitable for protecting 7.5V rails in general-purpose applications.
With a 7.5V reverse standoff voltage and 8.33V minimum breakdown, this part protects 5V and 3.3V logic rails from surges up to 1500W. The 12.9V clamping voltage ensures downstream ICs see less than 13V during a 116.3A pulse — well within the absolute maximum ratings of most MCUs and transceivers.
Active Production, Surface-Mount DO-214AB
The DO-214AB (SMC) package is a standard JEDEC footprint, widely second-sourced across the industry — if you need a backup, any 1500W bidirectional TVS in DO-214AB with the same standoff voltage is a drop-in candidate. Supplied on Tape & Reel (TR), it's ready for automated pick-and-place.
