Derate linearly to 150°C case temperature at the rate of 0.64 W/°C. Derate linearly to 150°C free air temperature at the rate of 24 mW/°C. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, IB(on) = 0.4 A, R BE = 100 Ω, VBE(off) = 0, RS = 0.1 Ω, VCC = 20 V. PRODUCT INFORMATION Information is current as of publication date. Products conform to specifications in accordance with the terms of Power Innovations standard warranty. Production processing does not necessarily include testing of all parameters. 1 BD245, BD245A, BD245B, BD245C NPN SILICON POWER TRANSISTORS JUNE 1973 - REVISED MARCH 1997 electrical characteristics at 25°C case temperature PARAMETER Collector-emitter breakdown voltage TEST CONDITIONS BD245 V (BR)CEO IC = 30 mA (see Note 5) VCE = 55 V ICES Collector-emitter cut-off current Collector cut-off current Emitter cut-off current Forward current transfer ratio Collector-emitter saturation voltage Base-emitter voltage Small signal forward current transfer ratio Small signal forward current transfer ratio V CE = 70 V V CE = 90 V V CE = 115 V ICEO IEBO VCE = 30 V V CE = 60 V VEB = VCE = V CE = V CE = IB = IB = VCE = V CE = 5V 4V 4V 4V 0.3 A 2.5 A 4V 4V VBE = 0 V BE = 0 V BE = 0 V BE = 0 IB = 0 IB = 0 IC = 0 IC = IC = IC = IC = 1A 3A 3A 3A (see Notes 5 and 6) 40 20 4 (see Notes 5 and 6) (see Notes 5 and 6) f = 1 kHz f = 1 MHz 20 3 1 4 1.6 3 V V IB = 0 BD245A BD245B BD245C BD245 BD245A BD245B BD245C BD245/245A BD245B/245C MIN 45 60 80 100 0.4 0.4 0.4 0.4 0.7 0.7 1 mA mA mA V TYP MAX UNIT hFE IC = 10 A IC = 10 A IC = 10 A IC = 0.5 A IC = 0.5 A VCE(sat) VBE hfe VCE = 10 V VCE = 10 V |hfe| NOTES: 5.
