The Littelfuse SMCJ40CA is a bidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients induced by lightning and other transient events. It offers a peak pulse power dissipation of 1500W for a 10/1000μs waveform, with a clamping voltage of 64.5V at a peak pulse current of 23.3A. The device has a standoff voltage of 40V and is rated for general purpose applications.
This TVS diode features a fast response time of less than 1.0ps from 0V to breakdown voltage, making it suitable for high-speed data line protection. It is housed in a DO-214AB (SMC) surface mount package, which is optimized for board space and provides built-in strain relief. The device is rated for an operating junction temperature range of -55°C to 150°C.
The SMCJ40CA is RoHS compliant, halogen free, and has a matte tin lead finish. It meets MSL level 1 per J-STD-020 and is suitable for reflow soldering at 260°C. The part is designed for use in telecom, computer, industrial, and consumer electronic applications where protection of I/O interfaces, VCC bus, and other vulnerable circuits is required.
