LESHAN RADIO COMPANY, LTD. Dual Series 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. • Extremely Fast Switching Speed • Low Forward Voltage — 0.35 Volts (Typ) @ I F = 10 mAdc LBAT54SWT1G 3 1 We declare that the material of product compliance with RoHS requirements. 2 SOT–323 (SC–70) CATHODE ANODE 1 ORDERING INFORMATION Device Marking Shipping LBAT54SWT1G B8 3000/Tape & Reel LBAT54SWT3G B8 10000/Tape & Reel 2 3 CATHODE/ANODE DEVICE MARKING LBAT54SWT1G= B8 MAXIMUM RATINGS (T J = 125°C unless otherwise noted) Rating Reverse Voltage Forward Power Dissipation @ T A = 25°C Derate above 25°C Forward Current(DC) Junction Temperature Storage Temperature Range Symbol Value VR PF IF TJ T stg Unit 30 Volts 200 1.6 200Max 125Max –55 to +150 mW mW/°C mA °C °C ELECTRICAL CHARACTERISTICS (T A = 25°C unless otherwise noted) Characteristic Reverse Breakdown Voltage (I R = 10 µA) 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 Min 30 — — — — — Typ — — 0.5 0.22 0.41 0.52 Max — 10 2.0 0.24 0.5 1.0 Unit Volts pF µAdc Vdc Vdc Vdc trr — — 5.0 ns VF VF IF IFRM IFSM — — — — — 0.29 0.35 — — — 0.32 0.40 200 300 600 Vdc Vdc mAdc mAdc mAdc Rev.A 1/3 LESHAN RADIO COMPANY, LTD.
