TIP41C

The TIP41C is an NPN bipolar power transistor in a TO-220 package, rated 100 V and 6 A continuous collector current with 65 W of power dissipation. It pairs with the PNP TIP42C in push-pull audio stages and H-bridges, and on its own it switches motors, relays, solenoids and LED strips from a low-current control signal.

TIP41C Specifications

TIP41C Applications

• Push-pull audio amplifier output stages with the TIP42C
• Low-side switching of DC motors, relays, solenoids and LED strips
• Linear voltage regulators and pass transistors

What's in the Box

• 1 × TIP41C NPN transistor

Tip: To switch a load from an Arduino, connect the emitter to ground, put the load between the positive supply and the collector, and drive the base through a resistor of about 220 Ω to 1 kΩ. With a gain as low as 15 at 3 A, heavy loads may need more base current than a pin can supply, so use a driver stage or a logic-level MOSFET for those, and add a flyback diode across inductive loads.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
