The 4 ns reverse recovery time makes it suitable for high-speed switching applications. The 200 V reverse voltage rating provides good margin for signal-level and low-power rectification. The tiny SOT-416FL footprint (1.0 x 0.6 mm) saves PCB space in high-density portable electronics. Low reverse leakage of 0.1 uA ensures minimal current loss in standby and bias circuits.","working_principle":"The 1SS400HM3T2B uses a PN junction silicon diode structure optimized for fast switching. In forward bias, current flows from anode to cathode with a forward voltage drop of approximately 1.2 V at 100 mA. When the bias is rapidly reversed, the stored minority carrier charge must be swept out before the diode blocks current. The 4 ns reverse recovery time indicates the time required for this process, making the diode suitable for high-frequency switching. The small junction area provides low capacitance and fast response but limits the forward current to 100 mA.","pin_description":"
