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
Surmetic™ 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 78 V
• Standard Zener Breakdown Voltage Range − 11.7 V to 91.3 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 Package is Available
Mechanical Characteristics

UL RECOGNITION
The entire series has Underwriters Laboratory
Recognition for the classification of protectors (QVGV2)
under the UL standard for safety 497B and File #116110.
Many competitors only have one or two devices recognized
or have recognition in a non-protective category. Some
competitors have no recognition at all. With the UL497B
recognition, our parts successfully passed several tests
including Strike Voltage Breakdown test, Endurance
Conditioning, Temperature test, Dielectric
Voltage-Withstand test, Discharge test and several more.
Whereas, some competitors have only passed a
flammability test for the package material, we have been
recognized for much more to be included in their Protector
category.
