SMF12CA

TVS Diodes SMF Series Description 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 deliverying one of the low height profiles (1.2mm) in the industry. Features       IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact) SOD-123FL surface mount package Protects one I/O line Peak power dissipation of 1000W under 8/20μs waveform Low leakage current Solid-state silicon avalanche technology    RoHS compliant Solder reflow temperature: Pure Tin-Sn, 260~270℃ Flammability rating UL 94V-0  Meet MSL level1, per J-STD-020 Applications SMF devices are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuit used in cellular phones, portable devices, business machines, power supplies and other consumer applications.
