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
- 400W peak pulse power capability at 10/1000µs waveform, repetition rate (duty cycle): 0.01%
- Compatible with industrial standard package SOD123FL
- Low profile: maximum height of 1mm
- Low inductance, excellent clamping capability
- For surface mounted applications to optimize board space
- Typical failure mode is short from over-specified voltage or current
