Its 1500W peak pulse power rating (10/1000 µs waveform) gives it the energy capacity for industrial surge environments — motor drives, relay kickback, or lightning-induced spikes on outdoor equipment. The reverse standoff voltage of 14V means it sits across the rail without conducting during normal operation; the minimum breakdown voltage of 15.6V defines where it starts to avalanche. Clamping is specified at 25.8V maximum at the peak pulse current of 58.1A, which is the voltage the protected circuitry must survive. ## Package and temperature envelope for the board Housed in the DO-214AB (SMC) surface-mount package, the same footprint used across the SMCJ14 family.","metaTitle":"SMCJ14CE3/TR13 TVS Diode – Microchip, 14V, 1500W, DO-214AB","metaDescription":"SMCJ14CE3/TR13 Zener TVS diode from Microchip Technology. 14V reverse standoff, 1500W peak pulse, bidirectional, DO-214AB SMC package.

That means it clamps transients of either polarity — useful for AC signal lines or bipolar power rails where the surge can swing positive or negative relative to ground."},{"question":"What is the closest pin-compatible alternative in the same family?","answer":"Within the SMCJ14 base number, the unidirectional variant (SMCJ14A) shares the same DO-214AB footprint and voltage ratings but protects only one polarity. For a bidirectional replacement, any SMCJ14C device from the same series is a direct fit; the '' suffix on this part indicates lead-free / RoHS-compliant plating.
