The SMC 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 SMC series is supplied in ON Semiconductor’s exclusive, cost-effective, highly reliable Surmetic package and is ideally suited for use in communication systems, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications.

• Standard Zener Breakdown Voltage Range — 6.8 to 91 V

• Stand–off Voltage Range — 5.8 to 78 V

• Peak Power — 1500 Watts @ 1 ms

• Maximum Clamp Voltage @ Peak Pulse Current

• Low Leakage < 5 µA Above 10 V

• UL Recognition

• Maximum Temperature Coefficient Specified

• Available in Tape and Reel

• Response Time is Typically < 1 ns

Mechanical Characteristics: CASE:

Void-free, transfer-molded, thermosetting plastic

FINISH: All external surfaces are corrosion resistant and leads are

readily solderable

POLARITY: Cathode indicated by molded polarity notch. When

operated in zener mode, will be positive with respect to anode

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 .
