The SMF58A from Littelfuse is a SMF series 200W unidirectional transient voltage suppression diode in SOD-123FL package. The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. SMF package is 50% smaller in footprint when compare to SMA package and delivering one of the low height profiles (1.1mm) in the industry. SMF devices are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuit.
