Introduction
The 1.5SMC series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Features
- Fast response time: typically less than 1.0ps from 0V to BV min
- Glass passivated chip junction
- High temperature to reflow soldering guaranteed: 260°C 30sec
- VBR @ Tj = VBR @ 25°C X (1 + αT × (Tj - 25)) (αT: Temperature Coefficient, typical value is 0.1%)
- Plastic package is flammability rated V - 0 per Underwriters Laboratories
- 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 finish material is tin(Sn) (IPC/JEDEC J - STD609A.01)
- 1500W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01%
- Excellent clamping capability
- Low incremental surge resistance
- Typical IR less than 1μA when VBR min > 12V
- For surface mounted applications to optimize board space
- Low profile package
- Built - in strain relief
- Typical failure mode is short from over - specified 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
- EFT protection of data lines in accordance with IEC 61000 - 4 - 4
Applications
- TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
