Transient Voltage Suppressors (TVS) are components used for over voltage protection in all kinds of different applications. CM1771-5006YL, also known as SMBJ17A-E3/52, is one type of TVS that is used to protect against transient voltages.

The CM1771-5006YL is a bi-directional silicon avalanche diode specifically designed for the protection of low voltage circuit lines from lightning induced transients. It provides ESD protection for five data and signal lines that are connected to its terminals. It can be engaged in either of two cases: bidirectional mode, and common-mode transient voltage clamping. This component is widely used in portable equipment, handheld devices, automotive systems, as well as other applications with low-voltage power supplies.

The working principle of the CM1771-5006YL is based on its construction. This device consists of several npn transistors that are connected together in parallel. The combination of the multiple npn transistors provides the ability to handle large current. Each transistor is designed to switch very quickly, enabling the device to respond quickly to surges in voltage. This allows it to turn off the power and prevent any further damage from being caused. The combination of the npn transistors also allows this device to dissipate large amounts of heat, thereby preventing any damage from occurring due to overheating.

The CM1771-5006YL is designed to clamp transient voltages at 18V. When a transient voltage spike occurs, the transistor switches will turn off the power and dissipate the excess energy. This ensures that no further damage is caused by the surge. The device can be used in both bidirectional and common-mode transient voltage clamps, depending on the application.

In addition to its over-voltage protection capabilities, the device also has built-in protection against ESD and EMI. Its EMI filter feature allows it to filter out any unwanted noise caused by high frequency radiation. This ensures that electromagnetic signals that are generated by other electrical components in the system do not interfere with the operation of the CM1771-5006YL.

The CM1771-5006YL has a wide application field and can be applied in a wide range of environments, including both commercial and automotive applications. Its high level of performance makes it the perfect choice for those looking for reliable protection against surge voltages.
