TIP41C NPN Power Transistor 100V 6A TO-220

The TIP41C is a general-purpose NPN bipolar junction transistor (BJT) in a TO-220 package, designed for medium-power linear and switching applications. With a 100V collector-emitter voltage rating and 6A continuous collector current, it handles demanding loads that small-signal transistors cannot. The complementary PNP pair is the TIP42C, making them ideal for push-pull and H-bridge configurations.

Key Specifications:

TO-220 Pinout (facing flat side with leads down):

• Pin 1 (left): Base (B)
• Pin 2 (centre): Collector (C) — also connected to metal tab
• Pin 3 (right): Emitter (E)

Applications:

• DC motor driver circuits
• High-current switching (relays, solenoids, lamps)
• Audio amplifier output stages
• Linear power supply regulation
• Push-pull and H-bridge configurations (with TIP42C)
• PWM load control

Note: For dissipation above ~1W, attach a heatsink to the TO-220 tab. The tab is electrically connected to the collector — use an insulating pad if mounting to a grounded heatsink.
