Bidirectional Zener TVS for 150V Rails
Its 1500W peak pulse power rating means it can absorb substantial surge energy without failing — a key parameter when derating for repetitive events or high ambient temperature. The device is rated for a reverse standoff voltage of 150V, so it stays transparent on a nominal 150V rail, only clamping when the voltage exceeds the 167V minimum breakdown threshold.
The SMC footprint is larger than the smaller SMA/SMB siblings, which means better heat dissipation through the solder pads — important when the device must handle repetitive surges near the 1500W limit. Lifecycle status is Active, so there is no imminent obsolescence risk.
