300W Transient Voltage Suppression Diodes Document Number: F12122A 19-JUL-2021 V 2.1 www.futurewafer.com.tw 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. 1-2. Feature List
