BD137 Description

Short technical summary and product information.

The BD137 is a silicon epitaxial planar NPN transistor housed in a SOT-32 plastic package. It is specifically designed for use in audio amplifiers and driver circuits, particularly those employing complementary or quasi-complementary configurations.

 

Key electrical characteristics include a maximum collector current (Ic) of 1.5A and a maximum collector-emitter voltage (Vce) of 60V. The device also offers a typical DC current gain (hFE) of 150 at 1.5A and a transition frequency (FT) of 150MHz under similar test conditions. The maximum power dissipation is rated at 8W.

 

This transistor is well-suited for applications requiring moderate power handling and amplification. Its design makes it a reliable component for general-purpose amplification tasks within its specified limits. The SOT-32 package is a standard surface-mount or through-hole component, depending on the specific variant, facilitating integration into various electronic designs.

 

Equivalent or alternate parts include BD115, BD130, BD131, BD132, BD135, and BD138, offering designers flexibility in component selection.
