1.5 kW peak pulse, 60 V standoff – DO-214AB Zener TVS
The SMCJ60E3/TR13 is a Zener-type TVS diode from Microchip Technology, rated for 1500W peak pulse power (1.5 kW) under the standard 10/1000 µs waveform. Its 60 V reverse standoff voltage makes it a fit for protecting 48 VDC or 60 V nominal rails where the clamping threshold must stay below downstream component ratings. The clamping voltage at peak pulse current is 107 V max, and the device can handle 14 A of peak pulse current. That 107 V clamp at 14 A gives a design margin check: if the protected circuit's absolute maximum is, say, 120 V, this part holds the transient below that ceiling.
Wide temperature range, single bidirectional channel
The single bidirectional channel means it clamps equally on positive and negative transients — useful on AC signal lines or DC rails where polarity reversal is possible. The breakdown voltage minimum is 66.7 V, giving a 6.7 V window above the 60 V standoff before the device starts conducting — typical for Zener TVS designs.
For a BOM line, this means you can commit the part without planning a replacement or stockpiling a lifetime buy.
