Available in both Tape & Reel (for automated pick-and-place) and Cut Tape (for prototyping or low-volume builds), the ordering code suffix -13 identifies the reeled variant. ## Sourcing and compliance The device is rated for General Purpose applications, meaning it is not restricted to a specific end-market qualification (e.g., AEC-Q automotive), but the wide temperature range and robust pulse rating make it suitable for industrial power supplies, telecom line cards, and consumer power-entry protection.","metaTitle":"SMCJ51CA-13 Diodes Inc TVS, 1500W Bidirectional, DO-214AB","metaDescription":"SMCJ51CA-13 TVS diode, 1500W peak pulse power, 51V standoff, bidirectional, DO-214AB.
