BD437G Description

Short technical summary and product information.

The BD437G is an NPN bipolar junction transistor from onsemi designed for general-purpose switching and linear amplification. It features a collector-emitter breakdown voltage of 45V and a collector current rating of 4A, making it suitable for medium-power applications.

 

Electrical characteristics include a minimum DC current gain (hFE) of 85 at 500mA and 1V, a maximum Vce saturation voltage of 800mV at 3A collector current, and a transition frequency of 3MHz. The device can dissipate up to 36W and operates over a junction temperature range of -55°C to 150°C.

 

Housed in a through-hole TO-126 package (also referenced as TO-225AA), the BD437G is suited for through-hole PCB assembly. It is commonly used in power switching circuits, driver stages, and linear amplifier applications where medium power handling and efficient thermal management are required.
