Product details

Clamp voltage and breakdown margin

The SMCJ45A-13-F: The 50V minimum breakdown voltage means avalanche conduction starts at least 5V above the 45V standoff — this guard band keeps the diode out of leakage during normal operation. The 72.7V clamp at 20.6A is the voltage the downstream circuitry must survive for the duration of the surge event.

DO-214AB SMC package — surface-mount surge protection

The DO-214AB (SMC) package is a standard surface-mount footprint for 1500W TVS diodes. It offers a larger body than the smaller SMA/SMB packages, which helps dissipate the heat from a 1500W pulse into the PCB copper. The SMC supplier device package code confirms the same mechanical outline.
