SMCJ400CA Description

Short technical summary and product information.

The SMCJ400CA is a bidirectional TVS diode from the SMCJ series manufactured by Littelfuse Inc. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

 

This device offers a peak pulse power dissipation of 1500W (10/1000μs waveform), with a reverse standoff voltage of 400V and a maximum clamping voltage of 648V at 2.3A peak pulse current. The SMCJ series features excellent clamping capability, low incremental surge resistance, and typical leakage current less than 1μA for breakdown voltages above 12V.

 

The SMCJ400CA is housed in a surface-mount DO-214AB (SMC) package, suitable for automated assembly. It is designed for general-purpose applications and supports operating temperatures from -55°C to 150°C. The series is halogen-free, RoHS compliant, and meets MSL level 1 per J-STD-020.

 

Applications include I/O interfaces, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The device provides ESD protection up to 30kV (air and contact) per IEC 61000-4-2 and fast response time typically less than 1.0ps.
