Bidirectional 1.5 kW TVS for 17 V rails
The SMCJ17CAE3/TR13 is a single-channel bidirectional Zener TVS diode rated for 1500 W peak pulse power (10/1000 µs waveform). The 17 V reverse standoff voltage sits below the 18.9 V minimum breakdown, and clamping is specified at 27.6 V maximum at the peak pulse current of 53.3 A. This window is tight enough to protect a 17 V nominal rail — say a 12 V battery bus boosted to 17 V — without false triggering on normal ripple.
Temperature range and package fit
Operating junction temperature spans -65°C to 150°C, which covers automotive under-hood, industrial outdoor, and military-grade environments without derating.
