Product details

1500W pulse clamping for 51V rails

The SMCJ51CA-13: The single bidirectional channel protects one signal or power line against both positive and negative transients, simplifying layout for AC-coupled or bipolar signal paths.

DO-214AB SMC package — board-fit note

Housed in the DO-214AB (SMC) surface-mount package, the device suits standard reflow soldering processes and occupies a compact footprint for 1500W-rated protection — the SMC body handles the thermal dissipation of the pulse without requiring through-hole mounting. 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.

Frequently asked questions

Where can I buy SMCJ51CA-13 and how do I get a price?

The SMCJ51CA-13 is an active Diodes Incorporated part available through independent and authorized distribution.

What is the SMCJ51CA-13's peak pulse power rating and what does it protect?

It clamps transients up to 82.4V maximum, protecting downstream circuitry on 48V to 51V rails from surges such as lightning-induced transients or inductive load switching.
