Its reverse standoff voltage of 30 V means it sits across the supply without conducting during normal operation; the breakdown voltage minimum of 33.3 V is the threshold where it starts shunting current. At the peak pulse current of 10.3 A (10/1000 µs waveform), the clamping voltage reaches 48.4 V — so the protected circuitry must tolerate that peak during a surge event. The single bidirectional channel simplifies BOM for AC-coupled lines or signal pairs where polarity reverses — no need to orient the diode.
Pulse power and temperature range — design margin check
Power line protection is not provided — this part is for signal or low-power DC rails, not AC mains or high-energy surge paths. If your application sees repetitive high-energy transients, a higher-power TVS or a separate MOV/varistor is needed.
The DO-214AC footprint is widely used, so cross-referencing to other manufacturers' 30 V bidirectional TVS diodes is straightforward if a second source is needed.
