How does temperature affect mosfets
WebFeb 4, 2024 · The most important reason for obtaining the ambient temperature is the fact that it directly affects the junction temperature or operating temperature. For example, with PCs, the ambient temperature is a measure of the air temperature of the surrounding computer equipment. Also, the most critical component in any PC is its microprocessor … WebThis positive temperature coefficient of the MOSFET makes it an ideal candidate for parallel operation in higher power applications where using a single device would not be practical or possible. Due to the positive TC of the channel resistance, parallel connected MOSFETs tend to share the current evenly among themselves.
