The LT4356IDE-3#TRPBF is a robust surge stopper device designed to protect electronics from high voltage transients and surges. Manufactured by Linear Technology, now part of Analog Devices, this component is engineered to safeguard sensitive automotive, industrial, and portable equipment from unexpected voltage spikes that can lead to catastrophic failure.

Key Features:

• Overvoltage Protection: The LT4356 regulates overvoltage events such as load dump in vehicles, by controlling the gate of an external N-channel MOSFET to act as a variable resistor, thus limiting the output voltage.
• Wide Operating Range: This device can handle a wide input voltage range from 4V to 80V, making it versatile for various applications.
• Adjustable Overvoltage Lockout: Users can set the desired overvoltage lockout threshold using an external resistor divider.
• Reverse Input Protection: It can withstand and protect against negative input voltages down to -40V without damage to itself or the load.
• Low Quiescent Current: With a low shutdown current of only 7μA, the LT4356 ensures efficient power management, making it suitable for battery-powered systems.

Applications:

• Automotive Electronics
• Industrial Control Systems
• Avionic and Marine Systems
• Transient Voltage Suppression
• Portable Instrumentation

The LT4356IDE-3#TRPBF is available in a 12-lead (4mm × 3mm) DFN package, offering a compact solution for space-constrained applications.
