Introduction
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.
Features
- EFT protection of data lines in accordance with IEC 61000-4-4
- Fast response time: typically less than 1.0ns from 0 Volts to VBR min
- Glass passivated junction
- Built-in strain relief
- Plastic package is fammability rated V-0 per UL 94
- Meet MSL level1, per J-STD-020, LF maximun peak of 260°C
- Matte tin lead–free plated
- Halogen-free and RoHS compliant
- Pb-free E3 means 2nd level interconnect is Pb-free and the terminal fnish material is tin(Sn) (IPC/ JEDEC J-STD609A.01)
- UL Recognized to UL 497B as an Isolated Loop Circuit Protector.
- 200W peak pulsepower capability at 10/1000µs waveform, repetition rate (duty cycle): 0.01 %
- Compatible with industrial standard package SOD-123FL
- Low profle: maximum height of 1.1 mm.
- Low inductance, excellent clamping capability
- For surface mounted applications to optimize board space
- High temperature to refow soldering guaranteed: 260°C/430sec
- Typical failure mode is short from over-specifed voltage or current
- Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
- IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
- ESD protection of data lines in accordance with IEC 61000-4-2
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
