Tip102 NPN Transistor
This content will be shared across all product pages.
The TIP102 is a widely used NPN Darlington transistor, which consists of two bipolar junction transistors (BJTs) connected in a Darlington configuration. This configuration allows it to achieve very high current gain, making it suitable for applications where high current switching and amplification are required.
