Normalized Thermal Transient Impedance, Junction-to-Ambient
Note
• The characteristics shown in the two graphs
- Normalized Transient Thermal Impedance Junction-to-Ambient (25 °C)
- Normalized Transient Thermal Impedance Junction-to-Foot (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.
