160V reverse standoff, 500W peak pulse — bidirectional TVS in DO-214AC
The SMAJ160CAE3/TR13 is a bidirectional Zener TVS diode from Microchip Technology, rated for a reverse standoff voltage of 160V and a peak pulse power of 500W (10/1000 µs waveform). It clamps transients to a maximum of 259V at 1.9A peak pulse current, providing overvoltage protection on DC rails up to 160V nominal. The single bidirectional channel protects against both positive and negative surges, simplifying the BOM on AC or bipolar DC lines where polarity is not fixed.
Junction temperature range and package
Housed in a DO-214AC (SMA) surface-mount package, it shares the same footprint as other SMAJ-series devices, allowing a drop-in replacement for existing 160V bidirectional protection without PCB layout changes.
The base product number SMAJ160 covers a family of unidirectional and bidirectional variants in the same package.
