In the hot summer, air conditioners and refrigerators have become the two most popular home appliances, because air conditioners can provide us with a cool and comfortable indoor temperature, while refrigerators can keep drinks cold and delicious. Thermostats play a key role in the constant temperature of air conditioners and refrigerators. Thermostats are composed of temperature sensors, flash memory, microcontrollers, display drivers, relays, etc., and today Dongzi wants to take you to explore the secrets of relays.

(PS: Strictly speaking, it is a photorelay)

In general thermostats, mechanical relays are mostly used between the MCU and the control circuit. Since mechanical relays have some physical contacts, the physical on/off operation will make noise, and long-term use can easily cause wear of the metal contacts, which seriously reduces the service life, thus causing higher costs for end users and developers. Compared with traditional mechanical relays, photorelays have made great progress. Photorelays are all composed of semiconductor devices (such as LEDs, photodiodes, and MOSFETs), which will not wear out, do not require maintenance, and greatly increase their service life. Photorelays composed of semiconductor devices have higher reliability and smaller size, which can better meet the market demand for beautiful thermostats in recent years. In addition, the drive circuit design of photorelays is simpler than that of mechanical relays, and the input current is lower, so low power consumption is also a major advantage of photorelays.

Dongzi once again emphasized that the advantages of photorelays are:

Save space, long service life, low power consumption!

Photorelays are known as the "main force to replace mechanical relays", so do you want to experience the magic of photorelays? The evaluation board TLP3107 is currently being applied for for free ! TLP3107 is a high-capacity photorelay with a 2.54SOP6 package and V OFF 60V/I ON 5A (@Ta=25℃). It can be directly installed on the mechanical relay mounting board to check the operation of the photorelay, making it easy for developers to get started quickly.

Now, you only need to fill in some simple information to have a chance to apply for the TLP3107 evaluation board for free . Click "Read More" to apply online immediately. Don't be too late!
