BD679

BD679 Transistor

The BD679 transistor is a high-power NPN Darlington transistor. It is designed for switching and amplifier applications. This component is ideal for hobbyists and professionals. It delivers reliable performance in many circuits.

This BD679 transistor combines two transistors in one package. This gives it very high current gain. It can amplify weak signals into strong outputs. The Darlington design means it needs very little base current. This makes it easy to drive with logic chips or microcontrollers. It switches on and off quickly for efficient operation. The built-in protection diodes prevent damage from inductive loads. This makes it safe for motors and solenoids. The TO-220 package lets you bolt it to a heatsink. This keeps it cool under heavy loads. You can use it in circuits from 5V to 80V. It works well in both linear and switching modes. The BD679 transistor is a workhorse for many electronics projects.
