SMCJ440CA Description

Short technical summary and product information.

The SMCJ440CA is a bidirectional TVS diode from Littelfuse Inc., part of the SMCJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. Key specifications include a reverse stand-off voltage of 440V, a clamping voltage of 713V at 2.1A peak pulse current, and a peak pulse power dissipation of 1500W (10/1000μs waveform). The device features excellent clamping capability, low incremental surge resistance, and a fast response time of less than 1.0ps. It operates over a temperature range of -55°C to 150°C. The SMCJ440CA is housed in a surface mount DO-214AB (SMC) package, suitable for automated assembly. It is RoHS3 compliant and meets MSL level 1 per J-STD-020. Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
