MJ15030 NPN Silicon Power Transistor

The MJ15030 is an NPN silicon power transistor designed for high-frequency, high-power switching and linear applications. It is widely used as a driver or output stage in high-fidelity audio amplifiers, switching regulators, and motor control circuits. Due to its high gain-bandwidth product (fT), it provides excellent switching speeds and low signal distortion, making it a reliable choice for professional audio equipment. The MJ15030 is the NPN complement to the MJ15031 PNP transistor, allowing for the design of efficient complementary symmetry output stages. Its TO-220AB package ensures that it can be easily mounted to a heat sink, which is necessary for maintaining stability when operating at its maximum 50-Watt power rating.

Key Features:

Collector emitter voltage (VCEO) rating of 150 Volts.

High DC current gain (hFE) of 20 to 100 at 2.0 Amperes.

Total power dissipation (PD) of 50 Watts at 25 degrees Celsius case temperature.

High transition frequency (fT) of 30 Megahertz.

Standard TO-220AB plastic package for thermal management.
