BAT54RALT1

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 BAT54RALT1 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES 3 3 ANODE 1 CATHODE 2 CATHODE 1 2 CASE 318–08, STYLE 12 SOT–23 (TO–236AB) DEVICE MARKING BAT54ALT1 = B6 MAXIMUM RATINGS (T J = 125°C unless otherwise noted) Rating Reverse Voltage Forward Power Dissipation @ T A = 25°C Derate above 25°C Operating Junction Temperature Range Storage Temperature Range Symbol VR PF Max 30 225 1.8 TJ T stg Unit Volts mW mW/°C °C °C –55 to +150 –55 to +150 ELECTRICAL CHARACTERISTICS (T A = 25°C unless otherwise noted) (EACH DIODE) 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) Symbol V (BR)R CT IR VF VF VF t rr VF VF 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 Unit Volts pF µAdc Vdc Vdc Vdc ns Vdc Vdc G10–1/2 BAT54RALT1 +10 V 820 Ω 2.0 k 0.1µF tr tp 10% t IF t rr t 100 µH IF 0.1 µF 50 Ω OUTPUT PULSE GENERATOR D.U.T. 50 Ω INPUT SAMPLING OSCILLOSCOPE 90% V R INPUT SIGNAL IR i R(REC) = 1.0 mA OUTPUT PULSE (I F = I R = 10 mA; MEASURED at i R(REC) = 1.0 mA) Notes: 1.
