1SMA5.0AT3G Series,
SZ1SMA5.0AT3G Series

400 Watt Peak Power Zener
Transient Voltage
Suppressors

Unidirectional

The SMA 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 SMA series is supplied in
ON Semiconductor’s exclusive, cost-effective, highly reliable
SURMETIC
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 − 5.0 V to 78 V
 Standard Zener Breakdown Voltage Range − 6.7 V to 91.25 V
 Peak Power − 400 W @ 1 ms
 ESD Rating of Class 3 (> 16 kV) per Human Body Model
 Response Time is Typically < 1 ns
 Flat Handling Surface for Accurate Placement
 Package Design for Top Slide or Bottom Circuit Board Mounting
 Low Profile Package
 SZ Prefix for Automotive and Other Applications Requiring Unique

Site and Control Change Requirements; AEC−Q101 Qualified and
PPAP Capable

 Pb−Free Packages are Available*
