ONSEMI MJ15015G NPN Power Transistor TO-3 15A

The ONSEMI MJ15015G is a high-performance silicon NPN bipolar power transistor designed for robust, linear applications where reliability and power handling are critical. Encased in a durable TO-3 metal package, this device is engineered to manage substantial current and thermal loads, making it a cornerstone component in professional and industrial electronic designs.

It excels in high-power audio amplifier output stages, providing clean, powerful sound reproduction. Its high current-gain bandwidth and exceptional safe operating area (SOA) also make it ideally suited for demanding motor drive control systems, such as driving stepping motors and managing other inductive loads. Furthermore, its capabilities extend to general industrial power management and linear regulation circuits.

Beyond linear applications, the MJ15015G is a reliable choice for power switching. It can effectively drive relays, solenoids, and other demanding inductive loads that exceed the capabilities of common transistors like the 2N3055. It is also well-suited for use in DC-to-DC converters and inverter circuits, offering enhanced durability and performance margins.
