7.6 Dissipation Ratings

See ⁽¹⁾⁽²⁾⁽³⁾⁽⁴⁾

PACKAGE	R_θJA THERMAL IMPEDANCE, JUNCTION TO AMBIENT	R_θJCTHERMAL IMPEDANCE, JUNCTION TO CASE (THERMAL PAD)	R_θJB THERMAL IMPEDANCE, JUNCTION TO BOARD
HKH	39.9°C/W	0.52°C/W	43.1°C/W

(1) Maximum power dissipation may be limited by overcurrent protection

(2) Power rating at a specific ambient temperature, T_A, should be determined with a junction temperature of 150°C. This is the point where distortion starts to substantially increase. Thermal management of the PCB should strive to keep the junction temperature at or below 150°C for best performance and long-term reliability. See power dissipation estimate in Application and Implementation for more information.

(3) Test board conditions:

2.5 inches × 2.5 inches, 4 layers, thickness: 0.062 inch
2-oz. copper traces located on the top of the PCB
2-oz. copper ground planes on the 2 internal layers and bottom layer
40.010-inch thermal vias located under the device package

(4) For information on thermal characteristics, see SPRA953.

A. See data sheet for absolute maximum and minimum recommended operating conditions.

B. Product operating life design goal is >15 years for 65°C ≤ T_J ≤ 95°C based on silicon technology characterization per MIL-PRF-38535.

C. The predicted operating lifetime versus junction temperature is based on reliability modeling using electromigration as the dominant failure mechanism affecting device wearout for the specific device process and design characteristics.
