The BD438 is a PNP bipolar junction transistor manufactured by STMicroelectronics. It is designed for general-purpose switching and amplification applications. The transistor is housed in a through-hole TO-225AA/TO-126-3 package, also known as SOT-32-3, which facilitates easy mounting on printed circuit boards.
The device features a maximum collector-emitter voltage of 45V and a maximum collector current of 4A, making it suitable for moderate power circuits. It can dissipate up to 36W of power, and its minimum DC current gain (hFE) is 30 at a collector current of 10mA and collector-emitter voltage of 5V. The maximum saturation voltage is 600mV at a base current of 200mA and collector current of 2A. The transition frequency is 3MHz, indicating suitability for low-frequency applications.
With a maximum junction temperature of 150°C, the BD438 can operate in environments with high thermal loads. The through-hole construction allows for straightforward integration into power supply, motor control, and audio amplification circuits. The part is listed as RoHS3 compliant, though this status is unverified and should be confirmed with the manufacturer.
