Note 1 For operating at ambient temperatures greater than +25°C, the NTE804 must be derated

based on a maximum +150°C junction temperature using a thermal resistance which de-

pends upon device mounting techniques.

Note 2 Dissipation characteristics are shown for four mounting configurations.

a. Infinite sink −13.4°C/W

b. PC board +V7 sink −21°C/WQ. PC board is 2 1/2 square inches. Staver V7 sink is 0.02

inch thick copper and has a radiating surface area of 10 square inches.

c. PC board only −29°C/W. Device soldered to 2 1/2 square inch PC board.

d. Free air −58°C/W.
