1SS400

1SS400 SURFACE MOUNT SWITCHING DIODE This device is an extremely fast switching diode housed in the ultra-small SOD-523 package. Ideal for applications where board space is at a SOD-523 FEATURES Extremely fast reverse recovery time to reduce switching losses Very low capacitance for reduced insertion losses Reverse voltage rating of 80V Also available in lead-free plating (100% matte tin finish) Cathode Band Indicates Polarity APPLICATIONS Mobile phones and accessories Hand-held computers High Speed Switching Applications Marking Code: 14 MAXIMUM RATINGS Rating Peak Reverse Voltage Continuous Reverse Voltage Continuous Forward Current TJ = 25°C Unless otherwise noted Symbol VRM VR IF I FSM P tot TJ Tstg Value 90 80 225 500 200 -55 to +150 -55 to +150 Units V V mA mA mW °C °C Non-repetitive Peak Forward Current, t = 1sec, Square Wave Total Power Dissipation (Note 1) Operating Junction Temperature Range Storage Temperature Range Note 1.
