Product details

What this TVS diode does on your rail

Its 16.7V minimum breakdown voltage means it starts conducting just above the normal operating voltage, and the 26.9V maximum clamping voltage at 55.8A peak pulse current limits the voltage the protected circuit sees during a surge.

Bidirectional protection in a single DO-214AB package

Microchip Technology is the brand, and the base product number SMCJ15 indicates a family of 1500W TVS diodes at various standoff voltages. For BOM planning, the part is sourced to order against your quantity — confirm lead time and current pricing through an RFQ. No direct second-source is listed, but the DO-214AB footprint is shared by many 1500W TVS diodes from other manufacturers, making cross-shopping straightforward if needed.

Frequently asked questions

Is SMCJ15CE3/TR13 bidirectional or unidirectional?

It is a single bidirectional channel, meaning it clamps transients of both polarities without needing an external series diode.

What is the difference between SMCJ15CE3/TR13 and SMCJ15A?

The SMCJ15A is typically a unidirectional version of the same 15V standoff, 1500W family, whereas the SMCJ15CE3/TR13 is bidirectional. The '' suffix often indicates a specific qualification or screening level from Microchip, but the core electrical ratings (breakdown, clamping, peak pulse power) are the same for both polarities. Confirm the exact SMCJ15A datasheet for its breakdown and clamping values.
