BD237G Description

Short technical summary and product information.

The BD237G is an NPN bipolar junction transistor from onsemi, designed for medium-power amplification and switching applications. It features a collector-emitter voltage rating of 80V, a collector-base voltage of 100V, and a continuous collector current of 2A. The device can dissipate up to 25W at a case temperature of 25°C, making it suitable for power stages in audio amplifiers and other medium-power circuits.

 

Key electrical characteristics include a DC current gain (hFE) of at least 25 at 1A collector current and 2V collector-emitter voltage, and a saturation voltage of 600mV at 1A collector current with 100mA base current. The transition frequency is 3MHz, and the device operates over a junction temperature range of -55°C to 150°C. The thermal resistance from junction to case is 5°C/W.

 

The BD237G is housed in a TO-225AA (TO-126-3) package with through-hole mounting, suitable for PCB assembly. It is Pb-free and RoHS compliant, meeting environmental standards for electronic components. This transistor is commonly used in complementary or quasi-complementary audio amplifier output stages, as well as in general-purpose switching and driver circuits.
