Zowie Technology Corporation 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODE Schottky Barrier Diode 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=10mAdc 3 ANODE CATHODE 2 3 CATHODE/ANODE BAT54RS 1 2 1 SOT-23 MAXIMUM RATINGS (TJ=125 C unless otherwise noted) Rating Reverse Voltage Forward Power Dissipation @ TA=25 C Derate above 25oC Forward Current (DC) Operating Junction Temperature Range Storage Temperature Range o o Symbol VR PF IF TJ TSTG Value 30 225 1.8 200 Max -55 to +125 -55 to +150 Unit Volts mW o mW / C mA o o C C ELECTRICAL CHARACTERISTICS (TA=25 C unless otherwise noted) Characteristic Symbol Min.
