LESHAN RADIO COMPANY, LTD. Dual Series Schottky Barrier Diodes LBAT54LT1 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. 3 1 2 • Extremely Fast Switching Speed • Low Forward Voltage — 0.35 Volts (Typ) @ IF = 10 mAdc SOT-23 • Pb-Free package is available CATHODE ANODE 1 3 DEVICE MARKING AND ORDERING INFORMATION Device Marking LBAT54LT1 JV3 LBAT54LT1G (Pb-Free) JV3 Shipping 3000/Tape&Reel 3000/Tape&Reel MAXIMUM RATINGS (TJ = 125°C unless otherwise noted) Symbol Value Unit Reverse Voltage VR 30 Volts Forward Power Dissipation @ TA = 25°C Derate above 25°C PD 225 2.0 mW mW/°C Forward Current (DC) IF 200 Max mA Junction Temperature TJ 125 Max °C Tstg – 55 to +150 °C Rating Storage Temperature Range ELECTRICAL CHARACTERISTICS (TA = 25°C unless otherwise noted) (EACH DIODE) Symbol Min Typ Max Unit V(BR)R 30 — — Volts Total Capacitance (VR = 1.0 V, f = 1.0 MHz) CT — 7.6 10 pF Reverse Leakage (VR = 25 V) IR — 0.5 2.0 µAdc Forward Voltage (IF = 0.1 mAdc) VF — 0.22 0.24 Vdc Forward Voltage (IF = 30 mAdc) VF — 0.41 0.5 Vdc Forward Voltage (IF = 100 mAdc) VF — 0.52 1.0 Vdc Reverse Recovery Time (IF = IR = 10 mAdc, IR(REC) = 1.0 mAdc) Figure 1 trr — — 5.0 ns Forward Voltage (IF = 1.0 mAdc) VF — 0.29 0.32 Vdc Forward Voltage (IF = 10 mAdc) VF — 0.35 0.40 Vdc Characteristic Reverse Breakdown Voltage (IR = 10 µA) Forward Current (DC) IF — — 200 mAdc Repetitive Peak Forward Current IFRM — — 300 mAdc Non–Repetitive Peak Forward Current (t < 1.0 s) IFSM — — 600 mAdc LBAT54LT1-1/3 LESHAN RADIO COMPANY, LTD.
