The 144V minimum breakdown marks where it commits and the 209V clamping ceiling is what your downstream IC actually sees when a surge arrives. ## Where a unidirectional Zener TVS fits in a design Unidirectional Zener-type TVS diodes clamp one polarity only — they protect positive-going transients on a DC rail. For AC lines or bipolar signals you need the bidirectional variant. Since this part is listed as general-purpose with power-line protection marked No, it is positioned for board-level transient suppression on telecom, industrial control, or instrumentation rails, not for mains-connected load-dump protection where a larger MOV or clamping IC would be required.","metaTitle":"1.5SMCJ130A Zener TVS Diode, 130V standoff, SMC","metaDescription":"Diotec 1.5SMCJ130A unidirectional Zener TVS, 130V standoff, 209V clamping, 1500W peak pulse.

A bidirectional (B) variant would clamp both polarities, which matters for AC lines or signals that swing below ground. If the protected node only sees positive excursions above Vcc, the unidirectional part is the right fit and the bidirectional variant adds no value."},{"question":"Does 1.5SMCJ130A have a pin-compatible equivalent in the same SMC footprint?","answer":"The DO-214AB SMC footprint is the industry standard for 1.5 kW unidirectional TVS series — multiple manufacturers offer pin-compatible parts at the same standoff voltage. Confirm the clamping voltage and peak pulse current match the 1.5SMCJ130A spec sheet before substituting, since the clamping characteristic is the protection-level parameter, not just the standoff rating.
