Important Notes & Differences Between Part Numbers:

️· The provided text includes multiple part numbers, and electrical characteristics *vary* between them. Carefully examine the tables on pages 3 & 5 to select the correct parameters for the specific part number you're using.
️· The parameters listed are often provided at specific test conditions (VGS, ID, temperature, etc.).
️· Some parameters (like VDS(on)) are dependent on the gate-source voltage (VGS) and the drain current (ID).
️· There is additional detail in tables available on pages 3 and 5 that are not fully presented here. These tables define key specs for different parts.
️· The text mentions a "Forward Biased Safe Operating Area" – refer to Figure 7 for details.

Test Conditions (Typical):

️· Temperature: Tc = 25°C unless otherwise noted.
️· Pulse Testing: Used for some parameters (like Qg) with specific pulse width and duty cycle.
️· Switching Measurements: Made using LEM TR-58 test equipment.

Where to find more information:

️· Pages 3 & 5: Contain comprehensive tables of electrical characteristics.
️· Figures 1-10: Provide graphical representations of performance (e.g., Output Characteristics, Safe Operating Area, Switching Waveforms).
