Product details

1500 W pulse rating and the clamping envelope

The SMCJ40AQ-13-F is a 1500 W (1.5 kW) peak-pulse-power Zener TVS rated for a 40 V reverse standoff voltage. The 64.5 V clamp ceiling is the number to budget for downstream voltage stress — the protected rail must survive that peak without latch-up or oxide rupture.

The operating junction temperature range spans -55°C to 150°C, covering the full automotive ambient envelope with margin for self-heating during a pulse.

Housed in a DO-214AB (SMC) package, the SMCJ40AQ-13-F is a surface-mount unidirectional device with a single protection channel. The SMC footprint is larger than the SMA/SMB siblings, which gives a lower thermal resistance to the board copper — a consideration for repetitive pulse applications where the average power dissipation matters.

Frequently asked questions

What is SMCJ40AQ-13-F's listed type and grade?

The device type is Zener (TVS), and the grade is Automotive (AEC-Q101 qualified). The unidirectional configuration protects a single rail per package.

What is the peak pulse power and clamping voltage for SMCJ40AQ-13-F?

The reverse standoff voltage is 40 V, minimum breakdown is 44.4 V, and maximum clamping is 64.5 V at 23.2 A peak pulse current.
