The BD909 is a silicon Epitaxial-Base NPN power transistor manufactured by STMicroelectronics, housed in a standard Jedec TO-220 plastic package. It is intended for use in power linear and switching applications. The complementary PNP types are BD910 and BD912.
Key electrical characteristics include a maximum Collector-Emitter Voltage (VCEO) of 80V and a maximum Collector Current (IC) of 15A. The device offers a maximum Total Power Dissipation (Ptot) of 90W at 25°C case temperature and a Thermal Resistance Junction-case (Rthj-case) of 1.4°C/W.
Additional specifications include a maximum Collector-Base Voltage (VCBO) of 80V and a maximum Emitter-Base Voltage (VEBO) of 5V. The DC Current Gain (hFE) varies with collector current, ranging from a minimum of 40 at 0.5A to 5 at 10A, with a typical value of 250 at 0.5A and 150 at 5A. The transition frequency (fT) is typically 3MHz at 0.5A and 4V.
The transistor operates within a storage temperature range of -65 to 150°C and a maximum operating junction temperature of 150°C. The TO-220 package is suitable for through-hole mounting.
