MJF122 Description

Short technical summary and product information.

The MJF122 is an NPN Darlington transistor manufactured by On Semiconductor, suitable for general-purpose amplifiers and switching applications. It is designed for isolated package applications where electrical isolation from the heatsink or chassis is required, eliminating the need for isolating washers.

 

Key electrical specifications include a collector-emitter voltage (VCEO) of 100V and a continuous collector current (IC) of 5A. The transistor features a high DC current gain (hFE) of 2000 (min) at 3A and 3V, and a Vce saturation of 3.5V (max) at 20mA and 5A. It can handle a total power dissipation of 2W at an ambient temperature of 25°C and 30W at a case temperature of 25°C.

 

This device operates within a junction temperature range of -65°C to 150°C. It is available in a TO-220FP package, designed for through-hole mounting. The MJF122 is electrically similar to the popular TIP122 and TIP127 transistors.
