SMF85A

The SMF series is designed specifcally 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 profles (1.1 mm) in the industry.

Applications

• Protection of I/O interfaces, VCC bus and other vulnerable circuit used in cellular phones
• Protection of I/O interfaces, VCC bus and other vulnerable circuit used in portable devices
• Protection of I/O interfaces, VCC bus and other vulnerable circuit used in business machines
• Protection of I/O interfaces, VCC bus and other vulnerable circuit used in power supplies
• Protection of I/O interfaces, VCC bus and other vulnerable circuit used in other consumer applications
