LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Notes
1. When operating at V
P
> 16 V, the output power must be limited to 85 W at THD = 10% (or minimum load is 6 Ω).
2. T
j
is a theoretical temperature which is based on a simplified representation of the thermal behaviour of the device.

+P×R
th(j-c)
, where R
th(j-c)
is a fixed value to be used for the calculation of T

. The rating for T

limits the
allowable combinations of power dissipation P and case temperature T
c
(in accordance with IEC 60747-1).
