Introduction

Solid state relays (SSRs) are widely used in industrial automation, communication, consumer electronics and other industries. It is an important component that connects the digital control and analog control of the circuit. TLP172GM is a high-isolation and low-on-resistance type solid state relay of Omron. It can ensure the high input/output voltage isolation between two terminals. With its small structure, high isolation voltage, low on-resistance and fast response features, it can improve the performance of the system to achieve optimal control.

Types and Applications

TLP172GM is a kind of three-terminal type solid state relay, which has multiple mounting options including surface mount, plug-in, pitch and wire wrapping. It is widely used in factory automation systems, PLC control systems, motion control systems, motor speed control systems, temperature control systems, vending machines, consumer electronics and other fields.

Features and Benefits

The maximum on-state resistance of TLP172GM is 500 mΩ and it can reduce power loss. It has a high input/output voltage isolation of 2500Vrms. The response time of the relay is short, which can ensure that the circuit can quickly achieve accurate control. In addition, it has advanced surge protection features which offer superior protection to your system in the event of electrical surges.

Working Principle

TLP172GM is composed of a silicon controlled rectifier (SCR) and an optically coupled light-emitting diode (LED) which use optical isolation to turn on the power switch. The SCR is a solid state device that can control the on/off state of the current. When the input terminal of the Solid State Relay is given a voltage or current signal of a certain value, the anode of the LED in the optocoupler will be illuminated. The light energy generated by the LED can be used to drive the SCR in the voltage output part, so that the SCR can turn on and off the power switch.

Conclusion

TLP172GM is a high-isolation and low-on-resistance type solid state relay of Omron. It has multiple mounting options, high input/output voltage isolation, fast response, and advanced surge protection features. Furthermore, its working principle is based on controlling the on/off state of the current with an optically coupled SCR and LED. It is widely used in industrial automation, communication, consumer electronics and other industries.
