LESHAN RADIO COMPANY, LTD. Schottky Barrier Diodes BAT54RALT1 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 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES 3 1 1 CATHODE 3 ANODE 2 2 CATHODE CASE 318-08, STYLE 12 SOT-23 (TO-236AB) DEVICE MARKING BAT54RALT1 = B6 MAXIMUM RATINGS (T J = 125C unless otherwise noted) Rating Symbol Max Unit Reverse Voltage Forward Power Dissipation @ T A = 25C Derate above 25C Operating Junction Temperature Range Storage Temperature Range VR PF 30 Volts 225 1.8 mW mW/C -55 to +150 -55 to +150 C C TJ T stg ELECTRICAL CHARACTERISTICS (T A = 25C unless otherwise noted) (EACH DIODE) 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) Symbol Min Typ Max Unit V (BR)R CT IR VF VF VF 30 -- -- -- -- -- -- 7.6 0.5 0.22 0.41 0.52 -- 10 2.0 0.24 0.5 1.0 Volts pF Adc Vdc Vdc Vdc t rr -- -- 5.0 ns VF VF -- -- 0.29 0.35 0.32 0.40 Vdc Vdc G10-1/2 LESHAN RADIO COMPANY, LTD.
