Tip41C NPN Power Transistor 100V 6A 65W TO-220

Tip41C NPN Power Transistor 100V 6A 65W TO-220

The TIP41C is a robust NPN bipolar power transistor produced using base-island technology and supplied in a TO-220 plastic package. Its mechanical construction prioritizes good thermal contact between the semiconductor die and the package backplate, allowing efficient heat transfer when attached to a heatsink. The device’s leadframe and encapsulation are designed for mechanical durability and straightforward PCB mounting, and the TO-220 form factor makes it easy to handle and replace in discrete assemblies.

At the semiconductor level the TIP41C uses a conventional bipolar layout optimized to manage moderate collector currents while keeping leakage and saturation behavior under control. The internal layout and manufacturing choices reduce parasitic elements, improving linearity and stabilizing switching response under normal drive conditions. The die/package combination balances thermal performance and compactness for typical discrete power circuits.

From an integrator’s viewpoint the offers a practical compromise between ruggedness and simplicity: compact enough for small assemblies yet able to tolerate repeated thermal cycling when properly mounted. Its documented mechanical data and standardized pinout simplify thermal-management decisions and system assembly. Documented by STMicroelectronics, the device follows common datasheet conventions and quality practices.
