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:
CASE: Void-free, transfer-molded, thermosetting plastic
FINISH: All external surfaces are corrosion resistant and leads are readily solderable
POLARITY: Cathode indicated by polarity band. When operated in zener mode, will be
positive with respect to anode
MOUNTING POSITION: Any
WAFER FAB LOCATION: Phoenix, Arizona
ASSEMBLY/TEST LOCATION: Guadalajara, Mexico

** 1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per minute maximum. (continued)
** MOSORB transient suppressors are normally selected according to the maximum reverse stand-off voltage (VRWM), which should be equal to or greater than the dc or continuous peak
***operating voltage level.
