Product details

500 W peak pulse power in a DO-214AC body

The clamping voltage at peak pulse current is 146 V max, which sets the voltage the downstream circuitry must survive during a surge event. Breakdown voltage min is 100 V, so the part starts conducting at that threshold and clamps the transient before it reaches the 146 V ceiling. The 3.4 A peak pulse current rating is the current the diode can sink during the 10/1000 µs pulse without failing.

Package and temperature range for board integration

Housed in a DO-214AC (SMA) package, the same footprint as many standard TVS diodes, so PCB layout reuse is straightforward.

Frequently asked questions

What is the peak pulse power of SMAJ90AE3/TR13?

500 W peak pulse power per the 10/1000 µs waveform. This is the maximum surge energy the diode can absorb in a single pulse before damage.

Is SMAJ90AE3/TR13 RoHS compliant?

Yes, the suffix in the order code indicates RoHS compliance. No additional documentation is needed for RoHS declarations.

What is the difference between SMAJ90AE3 and SMAJ90A?

The SMAJ90AE3 includes the RoHS compliance suffix; the SMAJ90A is the base part without that suffix. Electrically they are identical — same 500 W peak pulse power, same 90 V standoff, same DO-214AC package. The version is preferred for new designs requiring RoHS documentation.
