TECHNICAL DATA
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 A 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. {{ Surge current waveform per Figure 4 and derate per Figure 2. {{ VBR measured at pulse test current IT at an ambient temperature of 25C.
