Surge Suppression ICs: LT4356IMS-3#TRPBF Application Field and Working Principle

The LT4356IMS-3#TRPBF is a small, high-efficiency, low-voltage surge suppression IC designed by Linear Technology. It is designed for applications such as audio, video, and telecoms (especially VoIP). This rugged part is also suitable for portable electronics, consumer electronics, industrial equipment, and communications applications. It offers exceptional suppression of transient voltage transients of 10, 100, and 1000 microsecond duration.

The LT4356IMS-3#TRPBF is a monolithic integrated circuit (IC) that features a high-voltage SIP-510 connector with eight pins and eight power pins. It has two separate leads connected to a high-current collector for maximum output voltage and current. Its unique shield construction reduces common-mode surge energy to below 200mJ peak. It has a maximum voltage of 60V and a maximum current of 10A.

The LT4356IMS-3#TRPBF surge suppressor also has an external pin that can be used to monitor the transient voltage on the output pin. It it also features a ground fault protection method that triggers when the voltage on the output pin exceeds the 32V threshold. The surge suppressor can be used in applications where it needs to limit the rising voltage of over-voltage transients while maintaining the system’s power supply voltage. It has an extended temperature range of -40°C to +125°C.

The working principle of the LT4356IMS-3#TRPBF is quite simple. The suppressor works by intercepting the transient voltage that occurs during over-voltage transient and then dissipates it to ground. It works by rapidly moving current through the suppressor to ground and doing so in a fraction of the time that a non-surge suppressor would. This current movement allows the suppressor to limit the rise in voltage on the system by passing the energy to ground instead of allowing it to overload the system’s power supply.

The LT4356IMS-3#TRPBF surge suppressor is a versatile IC that is suitable for a variety of applications, including audio, video, and telecoms. Its fast response time and robust structure make it an ideal choice for many power protection needs. The suppressor is designed to guard against over-voltage transients while maintaining the system’s power supply voltage. By using its internal current-monitoring pins, the user can quickly and easily monitor the situation and restore the system if necessary.
