Working Principle of PG1101W-TR

The PG1101W-TR is designed to convert electrical energy into visible light energy. To do this, it uses an IGBT, or insulated gate bipolar transistor, as the switch in the driver circuit. The IGBT is a three-terminal device that has an electrically isolated gate region, which isolates the gate from the main conduction channel. The gate of the IGBT is connected to a signal from the controller, and when the signal is high, the IGBT turns on, allowing current to flow through the LED. When the signal is low, the IGBT turns off, cutting off the current to the LED. The IGBT is responsible for switching current at high speeds, allowing the LED to be driven to the desired levels efficiently.

Conclusion

The PG1101W-TR is a discrete semiconductor device specifically designed for LED indication. It is capable of driving up to 1.5A of current through the LED, providing a bright and highly visible light output.
