Product details

1500 W bidirectional TVS for a 13 V rail

Its single bidirectional channel handles both positive and negative surges, so one device covers a signal or power line without polarity concerns. Peak pulse power is rated at 1500 W (1.5 kW) under the 10/1000 µs waveform, and the clamping voltage at that power reaches 27.2 V maximum. The corresponding peak pulse current is 368 A under the 8/20 µs waveform, which is the more common surge test for telecom and industrial interfaces. The reverse standoff voltage of 13 V means the device draws negligible leakage below that level, and breakdown starts at a minimum of 14.4 V.

The part is rated for general-purpose applications per the listing, which in practice means power-supply input protection, telecom line cards, industrial I/O modules, and automotive auxiliary rails where a 13 V standoff fits.

Frequently asked questions

Is SMCJ13CA-TR bidirectional or unidirectional?

SMCJ13CA-TR is a single bidirectional channel device — it clamps both positive and negative transients on the same line.
