Designed for use as audio amplifiers and drivers utilizing complementary or quasi complementary circuits . BD139 is a three layer NPN or PNP device within the working range, the collector current IC is a function of the base current IB, a change in the base current giving a corresponding amplified change in the collector current for a given collector emitter voltage VCE. Features: Low saturation voltage. Simple drive requirements. High safe operating area. For low distortion complementary designs. Easy to carry and handle. Specifications: Transistor Polarity NPN Collector−Emitter Voltage (VCEO) 80V Collector−Base Voltage (VCBO) 80V Emitter−Base Voltage (VEBO) 5V Continuous Collector Current (Ic) 1.5A Continuous Base Current (Ib) 500mA Power Dissipation (Pd) 12.5W Operating Temperature Range -55 to 150°C DC Current Gain (hFE) 40-250 Thermal Resistance (ΘJA) 100°C/W Thermal Resistance (ΘJC) 10°C/W Length (mm) 7.5 Width (mm) 2.5 Height (mm) 10 Package Includes: 1 x BD139 NPN Bipolar Medium Power Transistor TO-126 Package. *Product Images are shown for illustrative purposes only and may differ from actual product.
