Product details

Surge protection that matches the rail voltage

The SMCJ10E3/TR13: Its 11.1V minimum breakdown voltage ensures it stays off during normal operation but fires fast when a surge hits, clamping to 18.8V max at 79.8A peak pulse current (10/1000µs waveform).

Microchip lists the SMCJ10E3/TR13 as Active. If your BOM calls for the bare SMCJ10, this reeled variant is electrically identical — just a different shipping format.

DO-214AB footprint — board layout constants

Housed in a DO-214AB (SMC) package, the SMCJ10E3/TR13 is a surface-mount device with a standard JEDEC footprint. The large copper pad on the cathode side (the tab) doubles as the primary heat path — the PCB land pattern should match the recommended pad geometry in the datasheet to keep the thermal impedance low during repetitive surge events. A 2-oz copper pour under the tab significantly improves the surge-withstand capability compared to a narrow trace.

Frequently asked questions

Is the SMCJ10E3/TR13 a direct replacement for the SMCJ10?

Yes — the base product number is SMCJ10, and the /TR13 suffix indicates Tape & Reel packaging. Electrically and mechanically, the die and package are identical; only the shipping format differs. If your BOM specifies SMCJ10, this reeled variant fits without a board change.

What package and footprint does the SMCJ10E3/TR13 use?

It comes in a DO-214AB (SMC) surface-mount package, with the supplier device package also listed as DO-214AB (SMCJ). The footprint is standard JEDEC; the cathode tab requires a generous copper pad for thermal management during surge.
