| Notes: RDS(on) values are based on VGS = 10V.
*Other RDS(on) values may apply for different gate voltage values.

3. Maximum Ratings:

️· VDSS (Drain-Source Voltage): Ranges from 60V to 100V depending on the specific device.
️· Operating Junction Temperature: -55°C to +150°C
️· Maximum Lead Temperature: 275°C for soldering.
️· Current Ratings: Vary depending on device type and temperature (see table above).

4. Dynamic Characteristics (Switching Times):

️· These MOSFETs have typical switching times of around 40-100 ns, but this can vary. The datasheet refers to Figures 1 and 2 for more detailed switching waveforms (which are not included in this excerpt).

5. Source-Drain Diode Characteristics:

️· VSD (Forward Voltage): Around 0.8 - 1.0V.
️· Reverse Recovery Time: Around 2.3 - 2.5 ns.

6. Important Notes:

️· RDS(on): This is a critical parameter (drain-source resistance when the device is "on"). Lower RDS(on) means less power is lost as heat. The values listed are based on a gate voltage (VGS) of 10V.
️· Temperature Dependence: The continuous drain current (ID) decreases as the device temperature increases. The table lists current values for both 25°C and 100°C.
️· Datasheet References: The datasheet references other sections (like Figures 1 and 2) for more detailed information.
