1.5SMCXXXAT3 Series

Zener Transient
V oltage Suppressors

GENERAL DATA IS APPLICABLE TO ALL
SERIES IN THIS GROUP

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.

Specification Features:

• 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:

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 .
