Product details

1500W surge clamp for 75 V rails

Its 1500 W peak pulse power rating (10/1000 µs waveform) handles surges up to 12.4 A, with clamping at 121 V maximum.

Protection window: standoff, breakdown, clamp

Reverse standoff voltage is 75 V — the rail voltage the diode leaves alone during normal operation. Breakdown starts at 83.3 V minimum, and the device clamps the transient at 121 V maximum at peak pulse current. This 46 V window between standoff and clamp defines the margin the downstream circuitry must survive. A single bidirectional channel protects both polarities on the same line, which simplifies board layout compared to pairing two unidirectional devices back-to-back.

Active lifecycle, single-source reality

This is a single-source part from Microchip; no direct second source is published. For BOM risk management, qualifying an alternate from the same DO-214AB TVS family before allocation tightens is a prudent step.

Frequently asked questions

What is the difference between SMCJ75CAE3/TR13 and SMCJ75A?

The SMCJ75CAE3/TR13 is a bidirectional device (one channel protects both polarities), while the SMCJ75A is a unidirectional device. The bidirectional variant simplifies layout when the rail can see both positive and negative transients.

What is the replacement for SMCJ75CAE3/TR13?

No official replacement or successor is published by Microchip Technology for this active part. For a pin-compatible alternate, look for other 1500 W, 75 V bidirectional TVS diodes in the DO-214AB package from the same product family.
