Multicomp Pro MJ15003 NPN Power Transistor, TO-3 Package

The Multicomp Pro MJ15003 is a high-performance, through-hole NPN silicon power transistor housed in a robust TO-3 metal can package. Designed for demanding linear applications, it offers a powerful combination of high voltage tolerance, substantial current handling, and significant power dissipation capabilities. Its rugged construction and thermal characteristics make it a reliable choice for professional and industrial electronic designs.

This transistor is engineered for stability and efficiency in high-power circuits. With a collector-emitter voltage (Vce) rating of 140V and a continuous collector current (Ic) of up to 20A, it can handle substantial loads. Its high power dissipation rating of 250W allows it to operate reliably in applications that generate significant heat, supported by a wide operating junction temperature range from -65°C to 200°C.

Key Features & Performance

• High Power Handling: A power dissipation of 250W ensures reliable performance in demanding environments.
• Excellent Linear Characteristics: Features a collector-emitter saturation voltage of just 1V at Ic=5A and a DC current gain (hFE) of 25 at the same current, promoting efficient switching and amplification.
• Robust Thermal Performance: The TO-3 metal package provides excellent heat dissipation, crucial for maintaining performance at high power levels.
• Versatile Application: Ideal for use in high-power audio amplifiers, linear power supplies, motor drives (such as disk head positioners), and other control circuits.

The through-hole mounting style and two-pin configuration facilitate secure and straightforward installation on printed circuit boards (PCBs), making it suitable for prototyping and permanent installations alike. Its compact dimensions ensure it can be integrated into a variety of chassis and enclosure designs.
