SMF5.0AT1/D
SMF5.0AT1 Series
Zener Transient
Voltage Suppressor
SOD−123 Flat Lead Package
The SMF5.0A Series is designed to protect voltage sensitive
components from high voltage, high energy transients. Excellent
clamping capability, high surge capability, low zener impedance and
fast response time. Because of its small size, it is ideal for use in
cellular phones, portable devices, business machines, power supplies
and many other industrial/consumer applications.
Specification Features:
• Stand−off Voltage: 5 − 170 Volts
• Peak Power − 200 Watts @ 1 ms (SMF5.0A − SMF58A)
Peak Power − 175 Watts @ 1 ms (SMF60A − SMF170A)
• Maximum Clamp Voltage @ Peak Pulse Current
• Low Leakage
• Response Time is Typically < 1 ns
• ESD Rating of Class 3 (> 16 kV) per Human Body Model
IEC61000−4−2 Level 4 ESD Protection
IEC61000−4−4 40 A ESD Protection
• Low Profile − Maximum Height of 1.0 mm
• Small Footprint − Footprint Area of 8.45 mm
