STMicroelectronics TIP3055 NPN Power Transistor TO-247 15A

The STMicroelectronics TIP3055 is a complementary silicon NPN power transistor housed in a through-hole TO-247 package, designed for a wide range of general-purpose, power linear, and switching applications. Manufactured using epitaxial base planar technology, this device delivers reliable performance where high current and power dissipation are required.

Key Specifications

This NPN transistor features a collector-to-emitter voltage (Vce) of 70V at a 100 ohm RBE, a continuous collector current (Ic) of 15A, and a power dissipation of 90W. It offers a collector-to-emitter saturation voltage of just 3V at a 10A collector current, reducing power loss. The device also provides a DC current gain (hFE) of at least 20 and operates with a junction temperature up to 150°C, ensuring stable operation in demanding conditions.

Applications

With its robust construction, the TIP3055 is well-suited for applications such as power management, consumer electronics, portable devices, and industrial equipment. Its capabilities make it versatile for both linear and switching circuits.

Technical Details

The transistor is a standard 3-pin TO-247 package, intended for through-hole mounting. It measures 43mm in height, 33mm in width, and 15mm in depth, and weighs approximately 2 grams.
