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:

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
