Littelfuse 1-Element Bi-Directional TVS Diode Surface Mount DO-214 Package 440V 1.5 kW SMCJ440CA

Littelfuse SMCJ440CA is a 1-element bi-directional transient voltage suppression (TVS) diode designed to protect sensitive semiconductor devices from voltage transients caused by lightning, inductive load switching, and other transient voltage events. This device comes in a space-saving surface mount DO-214 package and supports a peak pulse power dissipation of 1.5 kW, delivering robust clamping and protection for electronic circuits.

With a minimum breakdown voltage of 492 V and a maximum reverse stand-off voltage of 440 V, the SMCJ440CA guarantees dependable surge suppression. Its low incremental surge resistance and built-in strain relief provide enhanced durability under repeated transient events. The diode operates efficiently within a wide temperature range from -65 °C to 150 °C, suitable for industrial, automotive, manufacturing, and electronic equipment environments.

Fast response time, typically less than 1.0 picosecond, ensures immediate suppression of damaging voltage spikes ensuring circuit reliability. The package is halogen free and glass passivated to improve long-term stability. Low leakage current of about 1 μA minimizes power loss during normal operation.

This diode includes ESD protection features critical for safeguarding sensitive electronics in laboratory, industrial, and commercial applications. The surface mount design helps conserve PCB real estate while providing efficient transient voltage suppression.
