The BD439G is an NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications requiring moderate voltage and current handling. The device features a maximum collector-emitter voltage of 60V and a maximum collector current of 4A, making it suitable for a range of power control circuits.
Key electrical characteristics include a minimum DC current gain (hFE) of 40 at 500mA collector current and 1V collector-emitter voltage, and a maximum collector-emitter saturation voltage of 800mV at 300mA base current and 3A collector current. The typical transition frequency is 3MHz, indicating suitability for low-frequency switching applications.
The transistor can dissipate up to 36W of power and operates over a junction temperature range of -55°C to 150°C. It is housed in a through-hole TO-225AA/TO-126-3 package with a TO-126 supplier device package, allowing for straightforward PCB mounting and heat sinking.
This component is appropriate for use in power supply circuits, motor drivers, and other applications where a robust NPN transistor with 60V/4A ratings is required. The through-hole package facilitates manual assembly and prototyping.
