SMCJ150CA Description

Short technical summary and product information.

The SMCJ150CA is a bidirectional transient voltage suppression (TVS) diode from Littelfuse, part of the SMCJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. With a peak pulse power dissipation of 1500W (10/1000μs waveform), it provides robust clamping performance.

 

Key electrical specifications include a reverse stand-off voltage of 150V and a maximum clamping voltage of 243V at a peak pulse current of 6.2A. The device features a Zener technology and offers ESD protection up to 30kV (air and contact) per IEC 61000-4-2. It is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.

 

The SMCJ150CA is housed in a DO-214AB (SMC) surface mount package, with a supplier device package of DO-214AB (SMCJ). It supports surface mount mounting and operates over a junction temperature range of -55°C to 150°C. The device is RoHS compliant and meets MSL level 1 per J-STD-020.
