Overview
The VNS14NV04-E is a monolithic, fully autoprotected Power MOSFET developed by STMicroelectronics using their VIPower™ M0 technology. This device is designed to replace standard power MOSFETs in applications ranging from DC to 50 KHz. It features built-in thermal shutdown, linear current limitation, and an overvoltage clamp, providing robust protection in harsh environments. The VNS14NV04-E also offers diagnostic feedback through the input pin, allowing for the detection of fault conditions such as overtemperature.
