Product details

The SMCJ30AE3/TR13 is a unidirectional Zener TVS diode from Microchip Technology, rated for 1500W (1.5kW) peak pulse power under a 10/1000µs waveform — enough to clamp transients on 24V or 30V DC rails without avalanche breakdown during normal operation. Reverse standoff voltage is 30V, so it sits across a 24V or 28V supply bus and stays off until a surge pushes the line above the 33.3V minimum breakdown threshold. Clamping voltage at peak current is 48.4V max, which keeps downstream components within a safe voltage window.

Peak pulse power and clamping performance

At 1500W peak pulse power, the SMCJ30AE3/TR13 sinks 31A of peak pulse current (Ipp) at the clamping voltage of 48.4V. No power line protection rating means this diode is not intended for continuous AC mains clamping — it is a transient suppressor, not a crowbar device.

Frequently asked questions

Is the SMCJ30AE3/TR13 RoHS compliant?

The AE3 suffix in the order code indicates Microchip's standard environmental compliance level, which includes RoHS exemption for lead in glass (exemption 7c-I) as typical for Zener TVS diodes. Confirm the latest compliance certificate with your Microchip representative or distributor.

What are direct equivalent alternatives to the SMCJ30AE3/TR13?

Pin-compatible alternatives from other manufacturers include the Littelfuse SMCJ30A series and Vishay SMCJ30A-/9AT — both in DO-214AB with the same 1500W rating and 30V standoff. Confirm the exact breakdown and clamping voltage match your design margin before substituting.
