That 28V standoff sits comfortably above a nominal 24V DC rail, so the diode stays out of conduction during normal operation but clamps before the downstream circuitry sees damaging overvoltage. The clamping voltage at 30A peak pulse current is 50V max, which is the ceiling the protected load must survive. ## Breakdown and clamping under surge Minimum breakdown voltage is 31.1V, giving a 3.1V window between the 28V standoff and the onset of avalanche conduction. That window absorbs normal rail ripple and transients without nuisance triggering. The 50V clamping ceiling at 30A peak pulse current defines the voltage stress the protected equipment must tolerate during a surge event. Peak pulse power of 1500W is the energy-handling capability for the standard 10/1000µs waveform — derate for shorter or longer pulses per the datasheet curve. Microchip lists the SMCJ28CE3/TR13 as Active. Housed in the DO-214AB (SMC) package, a surface-mount footprint common for 1500W-class TVS diodes. The wide temperature grade means the clamping behaviour stays predictable across the full mission profile.","metaTitle":"SMCJ28CE3/TR13 TVS Diode – 1500W, 28V, DO-214AB","metaDescription":"SMCJ28CE3/TR13 Zener TVS diode, 1500W peak pulse power, 28V reverse standoff, DO-214AB SMC package.

The 28V reverse standoff voltage provides margin above a 24V nominal rail, so the diode remains non-conductive during normal operation. The minimum breakdown voltage of 31.1V ensures it clamps only during overvoltage events. This is a standard choice for protecting 24V DC power inputs, sensor supplies, and industrial control lines."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/SMCJ28CE3-TR13","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/SMCJ28CE3-TR13 when reusing this data.
