This paper presents a comprehensive verification methodology and experimental results for the power MOSFET designated M3966M. The device is characterized as an N-channel enhancement-mode MOSFET intended for low-to-medium power switching applications. Verification includes DC parametric testing (threshold voltage, on-resistance, breakdown voltage, gate leakage), capacitive characterization, switching performance, and thermal reliability. All measured parameters are compared against a hypothetical datasheet specification. The device passes all verification tests within specified limits, confirming its suitability for intended use.
