SA5.0A/D
SA5.0A Series
Zener Transient
Voltage Suppressors
Unidirectional and Bidirectional
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
Surmetic 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.
Specification Features:
Stand–off Zener Voltage Range — 5 to 170 V
Peak Power — 500 Watts @ 1 ms
Maximum Clamp Voltage @ Peak Pulse Current
Low Leakage < 1 A Above 8.5 V
Maximum Temperature Coefficient Specified
Response Time is Typically < 1 ns
Mechanical Characteristics:
