Product details

What 130V standoff and 209V clamping mean for your circuit

The 1.5SMCJ130A: The 130V reverse standoff is the working voltage — the rail this diode watches without conduction. 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.

Frequently asked questions

What is the difference between 1.5SMCJ130A and a bidirectional TVS at the same standoff voltage?

The 1.5SMCJ130A is unidirectional — it clamps positive transients above the standoff voltage and ignores negative ones. 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.

Does 1.5SMCJ130A have a pin-compatible equivalent in the same SMC footprint?

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. Cross-reference at RFQ.

What compliance documentation does Diotec Semiconductor provide for 1.5SMCJ130A?

RoHS and REACH compliance documentation is available directly from Diotec Semiconductor — the standard documentation package for a European-listed passive and protection component. Confirm the specific revision and certificate format against your quality system's requirements at RFQ, as compliance documentation format varies by supplier.
