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 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 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 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
