0070.1121.B1

Transient voltage suppressors (TVS) are a type of electrical components that can protect circuits from high voltage and currents. These components come in various forms, such as varistors, metal-oxide varistors (MOVs), and zener diodes. The 0070.1121.B1 is a variable suppressor that can be used in switching power supplies to ensure that no high voltage transient or current occurs in the power supply.

Application Field

The 0070.1121.B1 is designed to protect against overvoltage and overcurrent in high-input devices such as TVs, air conditioners, computers, and base stations. It can also be used in power supplies, power inverters, and digital controllers. It is designed to withstand transient electrical events, such as lightning, inductive switching, and mechanical noise.

Working Principle

Variable suppressors work by detecting a voltage or current level that is higher than the rated power supply voltage and then suppressing the voltage or current to within safe levels. The 0070.1121.B1 has a minimum breakdown voltage of 70V, maximum required clamping voltage of 112V, and a maximum peak current of 1 Amp.

When an overvoltage or overcurrent occurs, the device is triggered into action. Each device is designed to absorb the current energy and dissipate the heat that is generated. The higher the current, the more heat it will dissipate, and the maximum current level it can handle will be limited. When the current level decreases, the device will return to its original state with no damage to the components.

When the 0070.1121.B1 is used for power supply protection, it is mounted on the power supply circuit board, usually near the power input connections. For best performance, it is recommended to mount the device as close as possible to the power supply input.

In conclusion, the 0070.1121.B1 is a variable suppressor that can be used to protect circuits from high voltage transients and currents. It is designed to absorb current energy and dissipate the heat generated, and can be used in high-input devices such as TVs, air conditioners, computers, and base stations. It is also suitable for power supplies, power inverters, and digital controllers.
