TIP142 -10 A 100V NPN Darlington Bipolar Power Transistor – TO-247

Description

1. Darlington Configuration: The TIP142 is configured as a Darlington pair, which provides very high current gain. This makes it ideal for applications where a small input current needs to control a much larger output current, such as in power amplification circuits.

2. High Current and Voltage Ratings: With a current rating of 10A and a voltage rating of 100V, the TIP142 can handle significant power levels, making it suitable for high-power applications including power amplifiers, motor control circuits, and other industrial applications.

3. TO-247 Package: The TO-247 package offers excellent thermal performance, enabling efficient heat dissipation. This is crucial for high-power applications where excess heat can damage the transistor or affect its performance. Proper heat sinking techniques are typically employed with TO-247 packages.

4. Versatility: The TIP142 can be used in a wide range of applications due to its high current and voltage ratings. It is commonly found in audio amplifiers, power supplies, motor control circuits, and various industrial control systems.

5. Fast Switching Speed: While Darlington transistors generally have slower switching speeds compared to single transistors, the TIP142 is designed for moderate-speed switching applications, making it suitable for applications where moderate switching speeds are acceptable given the advantages of its high current gain.

6. Reverse Biased Diode Protection: Like many Darlington transistors, the TIP142 has a built-in diode for protection against voltage spikes generated by inductive loads. This feature eliminates the need for an external diode in applications involving inductive loads such as relays and solenoids.
