1500 W of surge protection in a single bidirectional device
This part is designed for general-purpose surge protection on AC or bipolar signal lines where polarity is not fixed — the bidirectional construction means you do not need to worry about orientation during assembly or in-circuit.
For a 48 V or 60 V nominal bus with transients that could hit 150 V, this part leaves enough margin below the clamping ceiling to keep downstream silicon safe.
Package and mounting — DO-214AB (SMC)
Housed in the DO-214AB (SMC) package, this is a surface-mount device with a standard footprint shared across the SMCJ family. The SMC package is rated for the full 1500 W pulse without requiring a heatsink, relying on the PCB copper area for thermal dissipation.
