SMF Series TVS Diode

The Littelfuse SMF series 200 W low-profile package, transient voltage suppression (TVS) diode is designed specifically to protect sensitive electronic equipment from voltage transients induced by DC line spikes and ESD. Its industry-standard, SOD-123 plastic package provides a footprint that is just half the size of SMA packages, allowing designers to optimize the use of circuit board space in compact and slim products. The combination of compact size and 200 W peak pulse power surge capability at 10 x 1000 µS waveform make the SMF series 200 W TVS diode an excellent option for the protection of I/O interfaces, VCC bus, and other vulnerable circuits used in hard-disk drives, portable devices, business machines, cellular phones, and many other industrial and consumer applications.
