Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to this device. Functional operation at or near these
limitations will significantly reduce the lifetime of the device.
2. Dissipated power PD is in any combination of DC voltage, Drain Current, input power and power delivered to the load.
3. When operated at maximum PD with a base plate temperature of 85 °C, the median time to failure (MTTF) is significantly reduced.
4. These ratings apply to each individual FET. The operating channel temperature will directly affect the device MTTF. For maximum life, it is
recommended that junction temperatures (Tj) be maintained at the lowest possible levels. See MTTF vs. Tchannel Temperature Table.
