THERMAL RATINGS T
Note
The characteristics shown in the two graphs
- Normalized Transient Thermal Impedance Junction to Ambient (25 °C)
- Normalized Transient Thermal Impedance Junction to Case (25 °C)
are given for general guidelines only to enable the user to get a “ball park” indication of part capabilities. The data are extracted from single
pulse transient thermal impedance characteristics which are developed from empirical measurements. The latter is valid for the part mounted
on printed circuit board - FR4, size 1" x 1" x 0.062", double sided with 2 oz. copper, 100 % on both sides. The part capabilities can widely vary
depending on actual application parameters and operating conditions.
Vishay Siliconix maintains worldwide manufacturing capability. Products may be manufactured at one of several qualified locations. Reliability data for Silicon
Technology and Package Reliability represent a composite of all qualified locations. For related documents such as package/tape drawings, part marking, and
reliability data, see www.vishay.com/ppg?65704.
