MJF122G Description

Short technical summary and product information.

The ON Semiconductor MJF122G is a complementary power Darlington transistor designed for general-purpose amplifiers and switching applications. It is suitable for use where the mounting surface of the device must be electrically isolated from the heatsink or chassis, 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. It offers a high DC current gain (hFE) of 2000 (min) at 3A collector current. The transistor has a Vce saturation voltage of 3.5V maximum at 20mA base current and 5A collector current.

 

This device is packaged in a TO-220FP (Full Pack) configuration, designed for through-hole mounting. It operates within a junction temperature range of -65°C to 150°C. The total power dissipation is rated at 2W when ambient temperature is 25°C and 30W when case temperature is 25°C.

 

The MJF122G is electrically similar to the popular TIP122 and TIP127 series, offering reduced system cost and UL recognition for isolation up to 3500 VRMS.
