The threshold voltage

WebMicrosemi SiC MOSFETs have a minimum threshold voltage of 1.7 V at 25 °C. The typical temperature coefficient of the threshold voltage is –6 mV/°C. Operation at an elevated junction temperature of 175 °C results in a threshold shift to roughly 1.7 V – (175–25) * 6 mV = 0.8 V. This threshold voltage is by WebJan 13, 2024 · 93. 5. trurle said: No. Conductivity decrease with increased temperature is a separate effect from narrowing of bandgap which results in threshold voltage shift. And regarding current, mobility degradation typically dominates over threshold voltage shift unless transistor biased in very narrow range of gate voltages near threshold voltage.
