2pcs Tip31c Transistor

🔹 2pcs TIP31C NPN Power Transistor – TO-220 Package

This pack includes two TIP31C NPN bipolar junction transistors, designed for medium-power switching and amplification applications. Housed in a standard TO-220 package, these transistors are widely used in motor drivers, power supplies, audio amplifiers, and general-purpose electronic projects.

✅ Specifications:

• Transistor Type: NPN Bipolar Junction Transistor (BJT)

• Part Number: TIP31C

• Package: TO-220

• Collector-Emitter Voltage (Vceo): 100V

• Collector-Base Voltage (Vcbo): 100V

• Emitter-Base Voltage (Vebo): 5V

• Collector Current (Ic): 3A (Continuous)

• Power Dissipation (Pd): 2W (at 25°C ambient) / 40W (at 25°C case temperature with proper heatsink)

• DC Current Gain (hFE): 10–50 (at Ic = 3A, Vce = 4V)

• Transition Frequency (ft): 3MHz (typical)

• Operating Temperature: -65°C to +150°C

• Quantity: 2 Pieces

⚠️ Important Note: Power dissipation is highly dependent on heatsinking. A proper heatsink is required for operation above ~2W. Without adequate cooling, the transistor may overheat and fail.

📦 Applications:
✔️ Medium-power switching circuits
✔️ DC motor drivers and speed controllers
✔️ Relay and solenoid drivers
