With a peak repetitive reverse voltage rating of 1000V and an average forward current rating of 1A, it is suitable for a wide range of line-frequency rectification applications. The glass passivation process ensures reliable operation with low reverse leakage current. The diode features a low forward voltage drop of 1.1V at rated current and can withstand non-repetitive surge currents up to 30A, providing robust performance during transient events. AEC-Q101 qualification makes it suitable for automotive applications. The SMA (DO-214AC) surface-mount package is optimized for automated assembly.","working_principle":"The S1M-E3\/61T operates as a standard PN junction rectifier diode with glass passivation for enhanced reliability: 1) PN Junction: The diode allows current flow in the forward direction (anode to cathode) while blocking current in the reverse direction up to the peak repetitive reverse voltage of 1000V. The glass passivation layer protects the junction surface from contamination and moisture, reducing leakage current and improving long-term reliability. 2) Forward Conduction: When forward-biased above the threshold voltage, the diode conducts with a low forward voltage drop of 1.1V at 1A, minimizing power dissipation in the application. 3) Reverse Blocking: In reverse bias, the diode blocks current flow with a typical leakage of only 1uA at rated voltage. The reverse recovery time of 1.8us represents the time required to switch from forward conduction to reverse blocking state.","pin_description":"
