2 / 5 page BD245, BD245A, BD245B, BD245C NPN SILICON POWER TRANSISTORS 2 PRODU CT INFORMA TION JUNE 1973 - REVISED SEPTEMBER 2002 Specifications are subject to change without notice. NOTES: 5. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle ≤ 2%. 6. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts. † Voltage and current values shown are nominal; exact values vary slightly with transistor parameters. electrical characteristics at 25°C case temperature PARAMETER TEST CONDITIONS MIN TYP MAX UNIT V(BR)CEO Collector-emitter breakdown voltage IC = 30 mA (see Note 5) IB = 0 BD245 BD245A BD245B BD245C 45 60 80 100 V ICES Collector-emitter cut-off current VCE = 55 V VCE = 70 V VCE = 90 V VCE =115 V VBE =0 VBE =0 VBE =0 VBE =0 BD245 BD245A BD245B BD245C 0.4 0.4 0.4 0.4 mA ICEO Collector cut-off current VCE = 30 V VCE = 60 V IB =0 IB =0 BD245/245A BD245B/245C 0.7 0.7 mA IEBO Emitter cut-off current VEB = 5 V IC =0 1 mA hFE Forward current transfer ratio VCE = 4 V VCE = 4 V VCE = 4 V IC = 1 A IC = 3 A IC = 10 A (see Notes 5 and 6) 40 20 4 VCE(sat) Collector-emitter saturation voltage IB = 0.3 A IB = 2.5 A IC = 3A IC = 10 A (see Notes 5 and 6) 1 4 V VBE Base-emitter voltage VCE = 4 V VCE = 4 V IC = 3 A IC = 10 A (see Notes 5 and 6) 1.6 3 V hfe Small signal forward current transfer ratio VCE = 10 V IC = 0.5 A f = 1 kHz 20 |h fe| Small signal forward current transfer ratio VCE = 10 V IC = 0.5 A f = 1 MHz 3 thermal characteristics PARAMETER MIN TYP MAX UNIT RθJC Junction to case thermal resistance 1.56 °C/W RθJA Junction to free air thermal resistance 42 °C/W resistive-load-switching characteristics at 25°C case temperature PARAMETER TEST CONDITIONS † MIN TYP MAX UNIT ton Turn-on time IC = 1 A VBE(off) = -3.7 V IB(on) = 0.1 A RL = 20 Ω IB(off) = -0.1 A tp = 20 µs, dc ≤ 2% 0.3 µs toff Turn-off time 1µs |
