Product details

100V rail protection in a 500W package

This bidirectional Zener TVS clamps at 162V maximum with a peak pulse current of 3.1A (10/1000µs waveform).

Wide temperature range for industrial environments

Rated for -65°C to 150°C junction temperature, the SMAJ100CAE3/TR13 can handle the thermal cycling found in outdoor telecom cabinets, motor drives, and battery management systems. The DO-214AC (SMA) surface-mount package keeps the footprint compact — 0.50 mm pitch is typical for this body size, so a standard reflow profile works.

Tape & reel delivery for automated assembly

Supplied in tape & reel (TR), this part is ready for pick-and-place without manual handling.

Frequently asked questions

Is SMAJ100CAE3/TR13 the correct replacement for SMAJ100CA?

The SMAJ100CAE3/TR13 is the tape-and-reel variant of the SMAJ100CA family. The '' suffix indicates RoHS compliance and lead-free finish. Electrically they are identical — same 100V standoff, 162V clamp, 500W peak pulse. If your BOM calls for SMAJ100CA, this part is a drop-in replacement as long as the package (DO-214AC) and polarity (bidirectional) match.

What is the peak pulse current rating of SMAJ100CAE3/TR13?

The peak pulse current is 3.1A for a 10/1000µs waveform. This is the current at the clamping voltage of 162V — enough to handle moderate transients on 100V rails. For higher-energy events you would step up to a larger package or higher power rating.

Does SMAJ100CAE3/TR13 meet RoHS and REACH?

The '' suffix in the order code designates RoHS compliance and lead-free termination finish. Microchip's standard parts are also REACH-compliant. No separate certificate is needed for most BOM audits, but request a compliance declaration with your quote if your QA process requires it.
