MJF18004 Description

Short technical summary and product information.

The MJF18004 is a bipolar junction transistor (BJT) manufactured by On Semiconductor. It is an NPN type with a collector-emitter sustaining voltage of 450V and a collector-base breakdown voltage of 1000V. The device supports a continuous collector current of 5A and a peak collector current of 10A under specified pulse conditions. It also has a maximum emitter-base voltage of 9V and a base current of up to 2A. The transistor is housed in a TO220FP package, suitable for through-hole mounting.

 

Designed for high-voltage switching and amplification, the MJF18004 is used in power supply circuits, motor control, and other high-voltage applications. Its thermal resistance junction-to-case is 1.65°C/W, and junction-to-ambient is 62.5°C/W, with a maximum operating temperature of -65°C to 150°C. Proper heat sinking and mounting are essential for optimal performance.
