Overview
The SMF4L series of SOD-123FL small and fat lead low profile plastic package is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
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
Key features
