Introduction to VDRS07H150TME

VDRS07H150TME is a voltage-dependent resistor (VDR) which is manufactured by the company Vishay. It is a high-current surge absorber used in a variety of consumer and industrial applications. The device is known for its high reliability and superior performance. It has a wide range of applications in various fields including automotive, power supplies, medical, and data communication.

Application Field of VDRS07H150TME

The VDRS07H150TME is used in a wide range of applications where its voltage and current sensitivity can be used to protect electronic circuits from the threat of surge events and power-related faults.In automotive applications, the VDRS07H150TME is often used to protect sensitive electronics from the threat of transients caused by voltage spikes due to engine start-up and sudden acceleration. Automotive electronics also benefit from better noise protection against electromagnetic interference (EMI) and radiofrequency interference (RFI) generated by spark plugs, alternators, and other components.The device is also used in power supply applications where it protects sensitive circuits from excessive voltage and current transients. This helps prevent permanent damage to electronic components, reducing component failure and failure of the entire system.In medical equipment, VDRS07H150TME is used to protect both the the user and the equipment from the risk of shock due to electric current leakage. This protects delicate electronic components and ensures reliable operation of medical equipment.Lastly, in data communication applications it is used to protect data lines from static electricity or other transients that can cause noise in data transmission or even damage to the internal components of the equipment.

Working Principle of VDRS07H150TME

VDRS07H150TME uses a basic electro-mechanical principle to ensure that it operates reliably over a wide range of operating parameters. The device consists of multiple layers of conductive and non-conductive material. When the device is exposed to excessive voltage or current, it acts like a mechanical fuse and opens, releasing the stored energy. This provides effective protection for the system by making sure that too much power will not reach sensitive components.The device is designed to work within a specific voltage and current range. It is designed to open its contacts when the voltage exceeds a specific value. When the voltage is lower than the specified limit, the device functions as a normal resistor and dissipates the current.The VDRS07H150TME is also designed with a mechanism to detect the current flow in the circuit, and it will open its contacts when the current exceeds its predetermined limit. This feature makes sure that the fault can be detected before it causes damage to the system.

Conclusion

The VDRS07H150TME is an effective device for providing protection for sensitive electronic circuits against voltage and current transients. It can be used in a variety of applications, such as in automotive, power supply, medical and data communication. Its operating principle is based on electro-mechanical principles, allowing it to provide reliable protection for the system. The device is designed to open its contacts when the voltage and/or current exceeds a specific limit, ensuring the safety of the system.
