Littelfuse 1.5SMC33A

The 1.5SMC series is designed specifcally 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 refow soldering guaranteed: 260°C/ 40sec
• IBR@TJ = IBR@25°C x (1+aT x (T - 25)) (aT:Temperature Coeffcient, typical value is 0.1% )
• 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
• 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)
