Thermal Considerations
tion that is relevant to the thermal performance of the PES16NT16G2 switch.
This section describes thermal considerations for the PES16NT16G2 (19mm
Note: It is important for the reliability of this device in any user environment that the junction temperature not exceed the T
specified in Table 19. Consequently, the effective junction to ambient thermal resistance (
maintained below the value determined by the formula:
Given that the values of T
achieve the desired
provided in Table 19), thermal resistance of the chosen adhesive (
