SACB30

The SACB30 is a 500W peak pulse power transient voltage suppression (TVS) diode from Littelfuse's SACB series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This device offers a standoff voltage of 30V and a clamping voltage of 48.6V at a peak pulse current of 10A (10/1000µs waveform). With a fast response time of less than 1.0ps from 0V to breakdown voltage, it provides excellent clamping capability for high-speed data lines and power buses.

The SACB30 is housed in a surface mount DO-214AA (SMB) package, making it suitable for compact PCB designs. It features a glass passivated chip junction for reliability and is rated for operating temperatures from -55°C to 150°C. The device is RoHS compliant, halogen free, 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.

Key specifications include a peak pulse power dissipation of 500W at 25°C (10/1000µs waveform), a maximum reverse leakage current of 1µA at 30V, and a typical junction capacitance of 45pF at 0V. The device is unidirectional with one channel and does not include power line protection. It is supplied in tape and reel packaging for automated assembly.
