1SMB10CAT3 Series
Watt Peak Power Zener
Transient Voltage
Suppressors
Bidirectional*
The SMB series is designed to protect voltage sensitive
components from high voltage, high energy transients. They have
excellent clamping capability, high surge capability, low zener
impedance and fast response time. The SMB series is supplied in
ON Semiconductor’s exclusive, cost-effective, highly reliable
Surmetict package and is ideally suited for use in communication
systems, automotive, numerical controls, process controls, medical
equipment, business machines, power supplies and many other
industrial/consumer applications.
Features
• Working Peak Reverse Voltage Range − 10 V to 75 V
• Standard Zener Breakdown Voltage Range − 11.7 V to 91.7 V
• Peak Power − 600 Watts @ 1 ms
• ESD Rating of Class 3 (> 16 KV) per Human Body Model
• Maximum Clamp Voltage @ Peak Pulse Current
• Low Leakage < 5 mA Above 10 V
• UL 497B for Isolated Loop Circuit Protection
• Response Time is Typically < 1 ns
• Pb−Free Packages are Available
