The breakdown triggers at 56.7V minimum, and the clamp holds at 82.4V maximum while shunting 18.2A of peak pulse current — this keeps the protected rail below the typical 100V abs-max of downstream DC-DC converters and transceivers. The 1500W peak pulse rating is defined with a 10/1000µs exponential waveform — the standard for telecom and automotive surge testing. For shorter pulses (8/20µs), the peak current capability is higher; for longer events, derate per the pulse-duration curve in the datasheet. ## DO-214AB SMC footprint and temperature range Housed in the DO-214AB (SMC) package with the SMC supplier device package designation, this TVS is a surface-mount part suited for reflow soldering. The SMC body handles the 1500W pulse without cracking the epoxy — the copper tab on the cathode side conducts heat into the PCB pad. The tape-and-reel packaging supports automated pick-and-place for high-volume production lines.","metaTitle":"SMCJ51AQ-13-F TVS Diode, 1500W, 51V, DO-214AB, AEC-Q101","metaDescription":"Diodes Inc SMCJ51AQ-13-F automotive TVS, 1500W peak pulse, 51V standoff, 82.4V clamp, DO-214AB SMC.
