Product details

The SMCJ6.5CAE3/TR13: That means no scramble for last-time buys or forced redesigns mid-cycle.

Clamping voltage and breakdown – the protection window

This is a bidirectional Zener TVS with a minimum breakdown voltage of 7.22V and a maximum clamping voltage of 11.2V at the peak pulse current of 133.9A. The 6.5V reverse standoff means it sits across a 5V or 6V rail without conducting in normal operation, then clamps hard when a transient exceeds the breakdown threshold.

1500W peak pulse – sizing the energy budget

The 133.9A peak pulse current is the current the diode must survive at the clamping voltage; derate for ambient temperature above 25°C per the datasheet curve.

Frequently asked questions

Can SMCJ6.5CAE3/TR13 replace SMCJ6.5A?

The SMCJ6.5A is a unidirectional version; the SMCJ6.5CAE3/TR13 is bidirectional. They share the same 6.5V standoff and 1500W rating, but the bidirectional part clamps both polarities. If the original design used a unidirectional TVS on a DC rail, a bidirectional replacement will still protect the rail but will not provide the same low-side clamping characteristic. Check the circuit polarity before substituting.

Is SMCJ6.5CAE3/TR13 RoHS compliant?

The suffix in the order code indicates Microchip's RoHS-compliant and halogen-free finish. The part is suitable for lead-free assembly processes.
