SMF3.3CA Thru SMF190CA
200W Transient Voltage Suppressors
TVS Diodes - 200W > SMF Series
Description
The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• For surface mounted applications in order to optimize board space
• Reliable low cost construction utilizing molded plastic technique
• Plastic material has UL flammability classification 94V-O
• Typical IR less than 1uA above 10V
• Fast response time: typically less than 1.0ps from 0 Volts to VBR min
• Glass passivated junction
• Low inductance
Package: SMF / SOD-123FL
Applications
• I/O interface • AC/DC power supply
• Low frequency signal transmission line (RS232, RS485, etc.)
