The S1 series (S1A through S1M) covers reverse voltage ratings from 50V to 1000V, with the S1B specifically rated at 100V for applications using 24VAC\/48VDC and lower supplies. The 1A average rectified current rating supports typical small power supply rectification tasks, while the 50A non-repetitive surge current rating (8.3ms single half-sine wave) provides ruggedness against inrush currents during initial power-up with capacitive loads. The 1.1V maximum forward voltage at rated current represents a moderate conduction loss of 1.1W at full load, manageable with standard PCB copper area in the SMB package. The 5uA maximum reverse leakage current at rated reverse voltage minimizes power waste when the diode is in the blocking state. The S1B is a commodity component available from multiple manufacturers, ensuring supply security and competitive pricing.","working_principle":"The S1B is a standard P-N junction rectifier diode. (1) Forward Bias: When the anode voltage exceeds the cathode voltage by approximately 0.7V or more, the diode conducts. The forward current is limited only by the external circuit impedance, and the forward voltage drop remains relatively constant at 0.9-1.1V. The forward voltage has a negative temperature coefficient, decreasing by approximately -2mV\/C as temperature increases. (2) Reverse Bias: When the cathode voltage exceeds the anode voltage (up to 100V), the diode blocks current flow. Only a small leakage current (5uA maximum) flows in the reverse direction. (3) Rectification: In AC-DC power supply applications, the diode conducts during the positive half-cycle of the AC input and blocks during the negative half-cycle, converting AC to pulsating DC. A filter capacitor smooths the pulsating DC into a relatively constant DC voltage. (4) Surge Withstand: The 50A surge rating reflects the diodes ability to absorb the energy from the initial charging of the filter capacitor after power-up.","pin_description":"
