TPSMD85A is one of the most widely used television protection device found in the audio industry. This device is also known as television Surge Protective Device (TVS). A TVS is an electronic component that protects television, radio sound devices, and other electronic equipment from overvoltage transients, which can cause serious damage to the equipment.

TPSMD85A devices are small, rugged signal protection components designed to protect sensitive audio and video components from overvoltage transients. They provide a balanced protection for DC, AC or RF signals. The device is capable of withstanding very high peak currents (10 times the rated current) due to its optimized internal structures and optimized peak current handling capability. They use a symmetrical high voltage breakdown technology for superior protection and it includes a reverse bias protection feature, which provides improved protection for RF signals.

The device has a peak pulse current rating of 150A with a maximum working voltage of 170VDC. It is a lead-free component with an operating temperature range of -55℃ to +150℃. It is UL, CSA and VDE approved and is suitable for all types of home and commercial applications. The device also has a low-power-loss characteristic, which makes it suitable for power distribution applications.

The working principle of the TPSMD85A is relatively simple. When an over-voltage surge occurs, the device will draw the current away from the TVS and dissipate it in the form of heat. The device is designed to limit the current to a safe level and protect the equipment from harm. The device includes a Reverse Bias Protection (RBP) circuit which works by limiting the amount of voltage that can pass through it.

The main application field of the TPSMD85A is in TV sound, video, and other consumer electronics equipment. It is commonly used in high-end consumer electronics, such as flat-screen TVs, stereo systems, and video gaming consoles. It also finds applications in industries like medical, automotive, military, aerospace, telecommunications, and networking.

In conclusion, the TPSMD85A is a reliable and cost-effective surge protection device that is designed to protect sensitive audio and video components from overvoltage transients. Its symmetrical high voltage breakdown technology provides superior protection and has a low-power-loss characteristic which makes it suitable for power distribution applications. Its main application field is in TV sound, video, and other consumer electronics equipment.
