BAT54LT1 Preferred Device 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. * Extremely Fast Switching Speed * Low Forward Voltage - 0.35 Volts (Typ) @ IF = 10 mAdc * Pb-Free Package is Available http://onsemi.com 30 VOLTS SILICON HOT-CARRIER DETECTOR AND SWITCHING DIODES 3 CATHODE 1 ANODE 3 MARKING DIAGRAM 1 3 MAXIMUM RATINGS (TJ = 125C unless otherwise noted) Rating 2 Symbol Value Unit Reverse Voltage VR 30 Volts Forward Power Dissipation @ TA = 25C Derate above 25C PF Forward Current (DC) 200 2.0 mW mW/C IF 200 Max mA Junction Temperature TJ -55 to +125 C Storage Temperature Range Tstg -55 to +150 C 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.
