Part points
-
The BD900A is a bipolar junction transistor (BJT), specifically designed as a Darlington pair, which combines two transistors in one package. This configuration provides high current gain and improved noise performance. The TO-220-3 package ensures efficient heat dissipation, making it suitable for linear applications where high power handling is required. In summary, the BD900A is a bipolar Darlington transistor designed for high current gain and linear application support.
-
Pinout
The BD900A is a PNP Darlington transistor with a TO-220AB package. It has three pins:
Emitter (EM): Acts as the input, controls the flow of current through the collector.
Collector (C): The output pin; it collects the charge from the emitter and passes it to the next component.
Base (B): A small resistance is provided between the emitter and collector. It's not a separate function pin but crucial for transistor operation. In summary, the BD900A has three pins: Emitter (control), Collector (output), and Base (required for proper transistor action). -
Manufacturer
The manufacturer of the BD900A is Bourns, a leading electronic component manufacturer. Founded in 1932, Bourns is known for producing high-quality resistors, inductors, and other passive components. The company operates globally and has a strong reputation within the electronics industry. -
Application Field
The BD900A, a BJT darlington NPN transistor, is typically used in applications requiring high current gain, voltage control, or as a buffer/signal amplifier in electronic circuits. -
Package
The BD900A has a TO-220-3 package type.
