1. Synopsis

1-1. General Description

The SMF Series Has Been Designed To Protect Sensitive

Equipment Against Electro-Static Discharges According to IEC

61000-4-2, MIL STD 883 Method 3015, And Electrical Over Stress

Such as IEC 61000-4-4 and 5. They Are Generally For Surges Below

300 W 10/1000 μs.

This Technology Makes It Compatible With High-End

Equipment And SMPS Where Low Leakage Current And High Junction

Temperature Are Required To Provide Reliability And Stability Over

Time. Their Low Clamping Voltages Provide a Better Safety Margin to

Protect Sensitive Circuits With Extended Life Time Expectancy.

Packaged in SOD123FL, This Minimizes PCB Space Consumption.
