SMDJ64CA

The Littelfuse SMDJ64CA is a high-energy bi-directional Transient Voltage Suppressor (TVS Diode) from the SMDJ series, specifically engineered for symmetrical clamping in medium-to-high voltage circuits. It is optimized for applications where bidirectional surges are common, such as AC-coupled lines, inductive load drivers, and systems prone to dual-polarity transient interference, quickly limiting voltage excursions in both directions to safe levels.

Housed in the standard DO-214AB (SMC) surface-mount package, this TVS diode delivers 3000W of peak pulse power under the 10/1000μs waveform, making it effective against moderate lightning strikes, switching transients, and induced surges. With a reverse standoff voltage of 64V, breakdown voltage starting at 71.3V, and maximum clamping voltage of 103V at 29.1A, it provides fast response time and low leakage current to maintain circuit stability during transient events.

The true bi-directional design eliminates polarity orientation requirements during PCB layout and assembly, simplifying design validation and reducing errors in automated production. Operating over a wide temperature range of -55°C to +150°C and fully RoHS-compliant, the SMDJ64CA is well-suited for industrial inverters, motor controls, communication power supplies, and renewable energy equipment where reliable surge protection is critical.
