With a peak pulse power rating of 1500W (1.5kW) under the 10/1000µs waveform, it handles surge events common in industrial power supplies, telecom equipment, and general-purpose DC bus protection. The DO-214AB (SMC) package is surface-mount, suited for automated assembly on standard PCB footprints.
Key clamping and breakdown ratings for your BOM
The reverse standoff voltage is 75V, meaning the diode does not conduct at normal operating voltage up to that level. Breakdown occurs at a minimum of 83.3V, and clamping is limited to 121V at the peak pulse current of 12.4A. For a 75V rail, the clamping margin is about 46V above the rail — enough to protect downstream components rated for 100V or higher.
Lifecycle and sourcing for the SMCJ75AE3/TR13
It ships in Tape & Reel for pick-and-place. Microchip has no official successor or alternative listed; the base number SMCJ75 covers the series, so confirm the exact suffix for your application.
