GENERAL DATA APPLICABLE TO ALL SERIES IN
THIS GROUP
Zener Transient Voltage Suppressors
Unidirectional and Bidirectional
Mosorb devices are designed to protect voltage sensitive components from high volt-
age, high energy transients. They have excellent clamping capability, high surge capabili-
ty, low zener impedance and fast response time. These devices are Motorola’s exclusive,
cost-effective, highly reliable Surmetic axial leaded package and are ideally-suited for use
in communication systems, numerical controls, process controls, medical equipment,
business machines, power supplies and many other industrial/consumer applications, to
protect CMOS, MOS and Bipolar integrated circuits.
Specification Features:
• Standard Voltage Range — 6.2 to 250 V
• Peak Power — 1500 Watts @ 1 ms
• Maximum Clamp Voltage @ Peak Pulse Current
• Low Leakage < 5 µA Above 10 V
• UL Recognition
• Response Time is Typically < 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
