Product details

TVS diode with 1500W peak pulse rating

The SMCJ40A-13-F: It clamps transients at 64.5V maximum when the surge current hits 23.2A. Reverse standoff voltage is 40V, meaning the device stays transparent on a 40V rail until an overvoltage event pushes past the 44.4V minimum breakdown threshold.

Package and board integration

Housed in a DO-214AB (SMC) package with a surface-mount footprint. The supplier device package is also SMC, so the soldering pad layout matches the standard JEDEC SMC outline.
