TECHNICAL DATA
Zener Transient Voltage Suppressors
Unidirectional and Bidirectional
The SA5.0A series is designed to protect voltage sensitive components from high volt-
age, 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 Motorola’s
exclusive, cost-effective, highly reliable Surmetic axial leaded package and is ideally-suited
for use in communication systems, numerical controls, process controls, medical equip-
ment, 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
µA
Above 8.5 Volts
•
Maximum Temperature Coefficient Specified
•
Response Time is Typically Less than 1 ns
Mechanical Characteristics:
