The 1KSMB18A is a 1000W transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It features a Zener breakdown voltage of 18V and a maximum clamping voltage of 25.5V at a peak pulse current of 39.2A.
This unidirectional device offers a fast response time of less than 1.0 ps from 0V to breakdown voltage, making it suitable for high-speed data line protection. It is rated for a peak pulse power dissipation of 1000W (10/1000μs waveform) and can handle a peak forward surge current of 120A (8.3ms half sine wave). The operating temperature range is -55°C to 150°C.
The 1KSMB18A is supplied in a surface-mount DO-214AA (SMB) package, which is compatible with standard reflow soldering processes (260°C/40 sec). It is RoHS compliant, halogen free, and has a Pb-free E3 terminal finish. Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
