MMBD717LT1 Preferred Device Common Anode Schottky Barrier Diodes These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. Extremely low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited. Features • Extremely Fast Switching Speed • Extremely Low Forward Voltage − 0.28 V (Typ) @ IF = 1 mAdc • Pb−Free Package is Available MAXIMUM RATINGS (TJ = 125°C unless otherwise noted) Rating Symbol Value Unit Reverse Voltage VR 20 V Forward Power Dissipation @ TA = 25°C Derate above 25°C PF 200 1.6 mW mW/°C Operating Junction Temperature Range TJ −55 to +150 °C Storage Temperature Range Tstg −55 to +150 °C http://onsemi.com 20 VOLT SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES CATHODE 1 ANODE 3 2 CATHODE 1 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
