Zener TVS, 1500W, 66.7V breakdown, bidirectional
The SMCJ60CE3/TR13 is a Zener-type transient voltage suppressor from Microchip Technology, rated for 1500W peak pulse power (10/1000µs waveform). The minimum breakdown voltage is 66.7V, clamping at 107V with a peak pulse current of 14A. The wide temperature span suits outdoor, automotive, and industrial environments where ambient extremes are routine.
The 66.7V minimum breakdown voltage sets the threshold where the device starts to avalanche. In practice, a 60V nominal rail (reverse standoff) will see the TVS begin conducting above 66.7V, clamping the surge at 107V maximum. The 14A peak pulse current (10/1000µs) is the current the device can handle at that clamping voltage — enough for typical industrial surge events on 48V or 60V DC buses. Because it is a Zener-type suppressor (not a MOV or gas tube), the clamping response is fast and the voltage overshoot is minimal. The 1500W rating is the peak power dissipation; derate for higher ambient temperatures per the datasheet curve.
Active production — sourcing and lifecycle
The DO-214AB package is widely stocked across distribution, so lead times are typically short for this active line.
