SA5.0A Series
500 Watt Peak Power
MiniMOSORBt Zener
Transient Voltage
Suppressors
Unidirectional
The SA5.0A 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 SA5.0A series is supplied in
ON Semiconductor's exclusive, cost‐effective, highly reliable
Surmetict axial leaded 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.

UL RECOGNITION*
The entire series including the bidirectional CA suffix has
Underwriters Laboratory Recognition
for the classification
of protectors (QVGV2) under the UL standard for safety
497B and File #E 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.
*Applies to SA5.0A - SA170A.
