BD682 Description

Short technical summary and product information.

The STMicroelectronics BD682 is a PNP Darlington transistor designed for medium-power switching and amplification applications. It features a maximum collector-emitter breakdown voltage of 100V and a continuous collector current rating of 4A. The device offers a high DC current gain (hFE) of at least 750 at 1.5A collector current and 3V Vce, enabling efficient current amplification with low base drive requirements.

 

For power handling, the BD682 can dissipate up to 40W, making it suitable for circuits that need moderate power control. The saturation voltage is specified at a maximum of 2.5V when base current is 30mA and collector current is 1.5A. The transistor is housed in a through-hole TO-225AA / TO-126-3 package (also designated as SOT32-3), which allows for easy mounting on printed circuit boards.

 

The component operates with a maximum junction temperature of 150°C. Common application areas include general-purpose switching, relay drivers, lamp drivers, and power linear amplifiers. The through-hole package provides robust mechanical attachment and good thermal conductivity to the board.
