Product details

1500W bidirectional clamp for 12V rails

The 1.5SMC12CH: It clamps transients on a nominal 12V bus: reverse standoff voltage is 9.72V, breakdown starts at 10.8V, and clamping is held to 17.3V at the 91A peak pulse current.

Package and assembly fit

Housed in a DO-214AB (SMC) package, this is a surface-mount device supplied on Tape & Reel for pick-and-place. The SMC footprint is larger than the smaller SMA/SMB siblings — the extra copper area under the cathode tab helps spread the thermal pulse during a 10/1000µs surge, keeping the junction within its 150°C limit.

Frequently asked questions

What is the 1.5SMC12CH's peak pulse power rating?

The clamping voltage at that peak current is 17.3V, and the device handles 91A of peak pulse current.

Is the 1.5SMC12CH automotive qualified?

Yes, it carries AEC-Q101 qualification and is graded as Automotive. The operating junction temperature range is -55°C to 150°C, covering the under-hood thermal profile.
