Product details

Device identity and key clamping parameters

The SMCJ43A-13-F: When the transient exceeds the breakdown threshold, the diode clamps at a maximum of 69.4V while conducting 21.6A peak pulse current — this clamping voltage is the figure a downstream component must survive without damage.

Package and board-fit for DO-214AB SMC

Housed in the DO-214AB (SMC) surface-mount package, the SMCJ43A-13-F occupies a standard footprint shared across the SMCJ family. The supplier device package is SMC, and the mounting method is surface mount — the same pad layout serves the entire 1500W SMCJ series, simplifying BOM consolidation.
