The LT4356CS-3#PBF is a surge stopper designed by Linear Technology to protect loads from high voltage transients. It regulates the output during an overvoltage event, such as a load dump in vehicles, by controlling the gate of an external N-channel MOSFET. The device ensures that the load is protected by limiting the output voltage to a safe level without the need for fuses or bulky magnetic components.

Key Features

• Overvoltage Protection: The LT4356CS-3#PBF can withstand temporary overvoltage conditions, clamping the output to a user-defined voltage.
• Wide Operating Range: This surge stopper operates over a wide input voltage range, making it suitable for a variety of applications.
• Adjustable Output Clamp Voltage: Users can set the clamp voltage with an external resistor divider, providing flexibility in different use cases.
• Reverse Input Protection: The device protects itself and the load from negative input voltages down to -40V.
• Low Quiescent Current: It draws a minimal amount of current in shutdown mode, preserving battery life in portable applications.

Applications

The LT4356CS-3#PBF is highly versatile and can be used in a variety of applications where overvoltage protection is critical. Common applications include automotive electronics, industrial systems, avionics, and power supply protection. Its robust design ensures reliability in harsh environments, making it an ideal choice for systems that require a high level of protection.
