TIP41 Bipolar Power Transistor – Discrete Component
The TIP41 is a robust N‑PN bipolar junction transistor (BJT) designed for medium‑power switching and amplification tasks. With a collector‑emitter voltage rating of 100 V and a continuous current capability of 6 A, it can drive motors, LEDs, relays, and small audio amplifiers in classroom labs and hobby projects. Packaged in a TO‑220 case, the TIP41 is easy to mount on breadboards, perf‑boards, or heat‑sinking rigs, making it an ideal hands‑on component for any electronics curriculum.
What students will learn: By integrating the TIP41 into circuits, learners explore fundamental STEAM concepts such as semiconductor physics, current gain (β), heat dissipation, and the difference between linear and saturated operation. They gain practical experience designing driver circuits, calculating base resistors, and measuring performance with multimeters and oscilloscopes; skills that bridge theory and real‑world engineering.
Key features
- V<sub>CE</sub>(max) = 100 V, I<sub>C</sub>(max) = 6 A
- High current gain (h<sub>FE</sub> ≈ 30‑100) for efficient switching
- TO‑220 package with exposed metal tab for heat‑sink attachment
- Wide temperature range (–55 °C to 150 °C) for reliable operation in lab environments
Why it’s great for STEAM education
The TIP41’s versatility lets students experiment across science (studying charge carriers), technology (building motor drivers or audio amplifiers), engineering (designing thermal‑management solutions), art (controlling LED lighting for installations), and mathematics (applying Ohm’s and Kirchhoff’s laws). Its durable, low‑cost design encourages iterative prototyping, failure analysis, and creative problem‑solving, core goals of a hands‑on STEAM program.
