Zener Transient Voltage Suppressors
The SMB 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 SMB series is supplied in Motorola’s
exclusive, cost-effective, highly reliable Surmetic 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:
• Standard Zener Breakdown Voltage Range — 6.8 to 200 V
• Stand-off Voltage Range — 5 to 170 V
• Peak Power — 600 Watts @ 1 ms
• Maximum Clamp Voltage @ Peak Pulse Current
• Low Leakage < 5 µA Above 10 V
• UL Recognition
• Response Time 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 molded polarity notch. When operated in zener mode,
will be positive with respect to anode
MOUNTING POSITION: Any
LEADS: Modified L-Bend providing more contact area to bond pad
MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260°C for 10 seconds
WAFER FAB LOCATION: Phoenix, Arizona
ASSEMBLY/TEST LOCATION: Seremban, Malaysia

Note 1: A transient suppressor is normally selected according to the reverse ”Stand Off Voltage” (VR) which should be equal to or greater than the DC or continuous peak operating
voltage level.
* * VBR measured at pulse test current IT at an ambient temperaure of 25°C.

Stand Off Voltage. Applied reverse voltage to assure a
non-conductive condition (See Note 1).
This is the minimum breakdown voltage the device will
exhibit and is used to assure that conduction does not
occur prior to this voltage level at 25°C.
Maximum Clamping Voltage. The maximum peak voltage appearing across the transient suppressor when
