BAT54ALT1 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. http://onsemi.com Features 30 VOLT SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES • Extremely Fast Switching Speed • Low Forward Voltage − 0.35 V (Typ) @ IF = 10 mAdc • Pb−Free Packages are Available CATHODE 1 ANODE 3 2 CATHODE MAXIMUM RATINGS (TJ = 125°C unless otherwise noted) Rating Symbol Value Unit Reverse Voltage VR 30 V Forward Power Dissipation @ TA = 25°C Derate above 25°C PF 225 1.8 mW mW/°C Forward Current (DC) 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.
