Littelfuse 15SMC51A Transient Voltage Suppression Diode

The Littelfuse 1.5SMC series of transient voltage suppression (TVS) diodes are specifically engineered to safeguard sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. These surface mount devices feature a fast response time, typically less than 1.0ps, and offer excellent clamping junction capability. They are suitable for applications in telecom, computer, industrial, and consumer electronics, providing robust protection for I/O interfaces, VCC buses, and other vulnerable circuits. The devices are halogen-free, RoHS compliant, and meet stringent industry standards for ESD and EFT protection.
