| LESHAN RADIO COMPANY, LTD. Schottky Barrier Diodes LBAT54WT1 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) @ I F = 10 mAdc * Pb-Free package is available 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES 3 1 2 DEVICE MARKING AND ORDERING INFORMATION Device LBAT54WT1 LBAT54WT1G (Pb-Free) Marking B4 B4 Shipping 3000/Tape&Reel 3000/Tape&Reel SOT-323 (SC-70) 3 CATHODE 1 ANODE MAXIMUM RATINGS (T J = 125C unless otherwise noted) Rating Reverse Voltage Forward Power Dissipation @ T A = 25C Derate above 25C Forward Current(DC) Junction Temperature Storage Temperature Range Symbol VR PF 200 1.6 IF TJ T stg 200Max 125Max -55 to +150 mW mW/C mA C C Max 30 Unit Volts ELECTRICAL CHARACTERISTICS (T A = 25C unless otherwise noted) Characteristic Reverse Breakdown Voltage (I R = 10 A) Total Capacitance (V R = 1.0 V, f = 1.0 MHz) Reverse Leakage (V R = 25 V) Forward Voltage (I F = 0.1 mAdc) Forward Voltage (I F = 30 mAdc) Forward Voltage (I F = 100 mAdc) Reverse Recovery Time (I F = I R = 10 mAdc, I R(REC) = 1.0 mAdc, Figure 1) Forward Voltage (I F = 1.0 mAdc) Forward Voltage (I F = 10 mAdc) Forward Current (DC) Repetitive Peak Forward Current Non-Repetitive Peak Forward Current (t < 1.0 s) Symbol V(BR)R CT IR VF VF VF trr VF VF IF IFRM IFSM Min 30 -- -- -- -- -- -- -- -- -- -- -- Typ -- 7.6 0.5 0.22 0.41 0.52 -- 0.29 0.35 -- -- -- Max -- 10 2.0 0.24 0.5 1.0 5.0 0.32 0.40 200 300 600 Unit Volts pF Adc Vdc Vdc Vdc ns Vdc Vdc mAdc mAdc mAdc LBAT54WT1-1/3 LESHAN RADIO COMPANY, LTD.
