Littelfuse 3.0SMC28A

The 3.0SMC series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

• For surface mounted applications in order to optimize board space
• Low profile package
• 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)
• Ipp is specified @ 8/20μS surge waveform
• Built-in strain relief
• V @ T = V @25°C x (1+αT x (T - 25)) (αT:Temperature Coefficient, 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
• High temperature to reflow soldering guaranteed: 260°C/40sec
• 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)

• 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.
