LED Indication - Discrete is widely used in a variety of fields. Among them, the EAST3215WA0 application field and working principle is very important. As a kind of LED indication product, EAST3215WA0 has a variety of characteristics that are widely used in electronic equipment requiring indication. The application fields of EAST3215WA0 include various industrial control equipment, household appliances and instrumentation.

First of all, EAST3215WA0 is a kind of ultra small surface mount device with an output current of 20mA, which can be used as a low current television indicator, as well as a status indicator for audio equipment or flashing warning applications. Secondly, EAST3215WA0 is an efficient device with a wide range of supply voltages, from 2.4V to 24V. Thirdly, EAST3215WA0 has a very high operating temperature range from -40°C to 100°C, which is greatly suitable for applications requiring ruggedness and durability.

The working principle of EAST3215WA0 is relatively simple. It is composed of two main parts: a power supply circuit and an illumination circuit. The power supply circuit is an isolated DC switching power supply that supplies power to the LED. The illumination circuit contains a power MOS transistor, which is opened and closed according to the voltage signal received from the controller. When the MOS transistor is opened, the current reaches the LED, and the LED is illuminated.

When using this product, pay attention to the matching with the display effect of the controller. Generally, a digital controller with low pulse frequency is used, and the pulse wave is at a certain repeat frequency. The display effect of EAST3215WA0 is proportional to the pulse frequency and duty of the controller\'s output signal. Generally, normal output frequency and duty cycle are better.

In a nutshell, EAST3215WA0 is a highly efficient LED indication product, which is widely used in a variety of fields. It has a variety of advantages such as a wide range of supply voltages, a wide working temperature range, and an efficient power supply circuit. It is suitable for various industrial control equipment, household appliances and instrumentation. Finally, pay attention to the matching with the display effect of the controller when using this product.
