The QTLP9127GR is a discrete LED with a variety of applications. This LED is an advanced Single-LED Indicator Driver unit, an integrated device with the ability to directly switch LEDs for low power consumption. The QTLP9127GR is a surface mount device (SMD) of ultra-low profile height and will fit into tight spaces that conventional LEDs cannot fit in.

In terms of its application field, the QTLP9127GR LED was engineered for LED indications, LED backlight, LED message boards, and LED matrix systems. The operating temperature range of the LED is from -40°C to 85°C. The QTLP9127GR\'s high-efficiency switching technology has been designed to work with loads of up to 1A, 100mA or 50mA, with a peak forward current of up to 2A.

The QTLP9127GR\'s working principle is based on its ability to directly switch an LED load. It uses a high-speed CMOS buffer integrated circuit to set the output current of the LED and provide a logical input voltage range. When the logic level impedance is changed, the output current is automatically adjusted through an "auto-adjust" feature. In addition, the design of the QTLP9127GR also includes protection circuits against over-current and over-voltage, allowing for a safe operation of the LED.

The QTLP9127GR is a discrete LED with a variety of applications. Its use of advanced switching technology has enabled it to become a useful tool for LED indications, LED backlight, LED message boards and LED matrix systems. By using a CMOS buffer integrated circuit to adjust the output current and incorporate safety features, the QTLP9127GR is able to offer a reliable, low power consumption source for LED applications.
