With the A-type board: 4.7 W

With the B-type board: 3.4 W

With the C-type board: 2.8 W

Note:

The large values for allowable power dissipation make it possible to use this device without a heat sink. At the

very least, dissipation of 2.8 W is possible with a glass-epoxy single-layered board, and 4.7 W is obtained by

applying special design measures to the board. For details on the configurations of boards A, B, and C, refer to

‘Boards used in the evaluation of thermal dating’ on page 11.
