Littelfuse 1.5SMC51CA

The 1.5SMC series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

• 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%
