Overview
The 1KSMB series is designed specifcally to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
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.
Key features
- 1000W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01 %
- For surface mounted applications to optimize board space
- Low profle package
- 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
- EFT protection of data lines in accordance with IEC 61000-4-4
- Built-in strain relief
- V @ T = V @25°C x (1+αT x (T - 25)) (αT:Temperature Coeffcient, typical value is 0.1 %)
- Glass passivated chip junction
- Fast response time: typically less than 1.0ps from 0V to BV min
- Excellent clamping capability
- Low incremental surge resistance
- Typical |R less than 1μΔ when VBR max > 12V
- High temperature to refow soldering guaranteed: 260°C/40sec
- Plastic package is fammability rated V-0 per Underwriters Laboratories
- Meet MSL level1, per J-STD-020, LF maximun peak of 260°C
- Matte tin lead–free Plated
- Available in breakdown Voltage from 6.8V to 180V specially designed for automotive applications
- Offers high-surge rating in compact package: bridges the gap between 600W and 1.5KW
- 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)
