Product details

1500W surge clamp for 15V rails

The SMCJ15E3/TR13 is a unidirectional Zener TVS diode from Microchip Technology, rated for 1500W peak pulse power at 10/1000µs — sufficient to clamp short-duration transients on a 15V DC rail without letting the protected circuitry see more than 26.9V at the peak current of 55.8A.

Standoff, breakdown, and clamping window

Reverse standoff voltage is 15V (typ), so the diode is non-conducting below that DC level — the rail runs at 15V without leakage. Breakdown occurs at a minimum of 16.7V, and clamping is guaranteed at 26.9V max when the full 55.8A surge is applied.

Frequently asked questions

How can I order SMCJ15E3/TR13 or get a price?

Submit an RFQ for the SMCJ15E3/TR13. As an active Microchip part in tape-and-reel, it is sourced to order — current pricing and lead time are confirmed at quote time against your BOM quantity.

What does the suffix mean in SMCJ15E3/TR13?

The suffix on Microchip TVS diodes indicates RoHS compliance and lead-free termination finish. It does not change the electrical ratings — the same 1500W, 15V standoff parameters apply.

How does SMCJ15E3/TR13 compare to the base SMCJ15?

The base SMCJ15 shares the same electrical ratings (1500W, 15V standoff, 16.7V breakdown, 26.9V clamp). The suffix on this variant adds RoHS compliance and lead-free plating, while TR13 specifies tape-and-reel packaging. Electrically they are interchangeable.
