The 56.7V minimum breakdown voltage provides a guard band above the 51V standoff, so the diode stays transparent during normal operation and only conducts when the transient exceeds the threshold. ## Package and temperature envelope Housed in the industry-standard DO-214AB (SMC) surface-mount package, the SMCJ51A-13 shares the same footprint as other 1500W TVS diodes from Littelfuse, Vishay, and STMicroelectronics — a single PCB layout can qualify multiple sources without a board spin. Available in both Tape & Reel and Cut Tape options, the packaging supports automated pick-and-place assembly at any volume. The SMC body's 8.0mm x 6.8mm footprint and 2.3mm height fit standard clearance profiles on 1.6mm-thick PCBs. ## Sourcing and lifecycle position This is a current-production part available through authorized distribution and independent channels — no lifecycle risk for new designs or ongoing production. For BOM hedging, the SMCJ51A-13 is pin-compatible with other 1500W DO-214AB TVS diodes at the same 51V standoff voltage, including the Littelfuse SMCJ51A and Vishay SMCJ51A. The base product number SMCJ51 indicates the family; the -13 suffix denotes Diodes Inc's specific packaging code, not a functional difference.","metaTitle":"SMCJ51A-13 Diodes Inc TVS Diode, 51V Standoff, 1.5kW","metaDescription":"SMCJ51A-13 from Diodes Inc: Zener TVS diode, 51V reverse standoff, 82.4V clamp, 1500W peak pulse power in DO-214AB SMC.
