1500 W pulse rating, DO-214AB footprint
The SMCJ20A-13-F: At that pulse, it clamps at 32.4 V maximum while conducting 46.3 A peak pulse current. The 20 V reverse standoff voltage (working voltage) means it stays transparent on a 20 V rail and only starts conducting when the transient exceeds 22.2 V breakdown minimum. Housed in the DO-214AB (SMC) package, the footprint is a standard for medium-power TVS diodes — the same pad layout serves many 1500 W parts, so a BOM swap between suppliers often lands on the same copper land pattern. The operating junction temperature range spans -55°C to 150°C, covering industrial and automotive under-hood ambient conditions without derating at the high end.
Active lifecycle, no power line protection
Note the Power Line Protection field is marked No — this TVS is designed for signal and low-voltage DC rail protection, not for direct AC mains or high-energy power-line clamping. The 1500 W rating applies to the 10/1000 µs surge waveform; real-world energy handling at shorter pulses (8/20 µs) is higher, but the datasheet's peak current figure is the binding constraint for IEC 61000-4-5 compliance testing.
Tape and reel, cut tape options
The SMCJ20A-13-F is offered in Tape & Reel (TR) and Cut Tape (CT) packaging. The TR suffix indicates standard 13-inch reel quantities for automated pick-and-place assembly; the CT option suits prototype or low-volume builds where a full reel is unnecessary. The DO-214AB body is compatible with standard SMC footprint solder pads — no special stencil aperture is needed beyond the usual 0.25 mm paste thickness for a power-dissipating package.
