NCP346SN2T1G Description

Short technical summary and product information.

The NCP346SN2T1G is an overvoltage protection IC from On Semiconductor designed to protect sensitive electronic circuits from overvoltage transients and power supply faults. It features a nominal overvoltage threshold of 5.5 V and an overvoltage turn-off time of less than 1.0 µs, ensuring rapid disconnection of the input supply from the load. The device is built on a robust BiCMOS process and can withstand input voltage transients up to 30 V. It comes in a thin SOT-23-5 package with a TSOT-23-5 footprint, suitable for surface mount assembly. Typical applications include cellular phones, digital cameras, portable computers, PDAs, and other portable consumer electronics. The device is Pb-Free and RoHS compliant (unverified).
