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