DATA SHEET BAT54W SEMICONDUCTOR Schottky Barrier Diodes H 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 SOT–323 DEVICE MARKING AND ORDERING INFORMATION Device Marking BAT54W B4 3 CATHODE Shipping 1 ANODE 3000/Tape & Reel 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 Max Unit VR PF 30 Volts 200 1.6 200Max 125Max –55 to +150 mW mW/°C mA °C °C IF TJ T stg 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) http://www.yeashin.com Symbol V(BR)R CT IR VF VF VF Min 30 — — — — — Typ — 7.6 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 1 REV.02 20110725 RATING AND CHARACTERISTIC CURVES BAT54W 2.0 k 820 Ω +10 V 100 µH IF 0.1 µF tr 0.1µF tp IF t t rr 10% 90% D.U.T. 50 Ω OUTPUT PULSE GENERATOR 50 Ω INPUT SAMPLING OSCILLOSCOPE t i IR V R INPUT SIGNAL R(REC) = 1.0 mA OUTPUT PULSE (I F = I R = 10 mA; MEASURED at i R(REC) = 1.0 mA) Notes: 1.
