Product details

Surge protection for 16V rails – 500W bidirectional TVS

It delivers 500W peak pulse power per the 10/1000µs waveform, with a clamping voltage of 26V at the rated peak pulse current of 19.2A. Single bidirectional channel means it protects against both positive and negative surges, making it suitable for AC signal lines or bipolar DC buses where polarity reversal is possible.

Breakdown and standoff – where the protection window sits

Reverse standoff voltage is 16V, so the diode does not conduct at normal operating levels up to that rail. Minimum breakdown voltage is 17.8V, giving a guard band of about 1.8V before the TVS starts clamping.

Package and mounting – DO-214AC on tape and reel

This is a standard catalog part, so lead times are generally predictable through distribution channels. Confirm the exact suffix matches your BOM requirement.

Frequently asked questions

How does SMAJ16CAE3/TR13 compare to the unidirectional SMAJ16A?

SMAJ16A is a unidirectional TVS (single polarity clamp), while SMAJ16CAE3/TR13 is bidirectional. Both share the same 16V standoff and 500W peak pulse rating, but the bidirectional variant clamps both positive and negative transients, which is necessary for AC-coupled or bipolar signal lines. The unidirectional version has a lower clamping voltage for the same standoff because it uses a single Zener junction.

What is the peak pulse power of SMAJ16CAE3/TR13?

It is rated for 500W peak pulse power measured with a 10/1000µs waveform. At that power level, the clamping voltage is 26V and the peak pulse current is 19.2A.

Is SMAJ16CAE3/TR13 bidirectional?

Yes, it has one bidirectional channel, meaning it clamps surges of either polarity. This is indicated by the 'C' in the part number (SMAJ16C).
