Product specification
Vertical deflection power amplifier for
monitors
TDA4861
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); voltages referenced to substrate (pin 6);
unless otherwise specified.
Notes
1. Internally limited by thermal protection; switching temperature point at 160
±8 °C.
2. Equivalent to discharging a 200 pF capacitor through a 0
Ω series resistor.
THERMAL CHARACTERISTICS
The heatsink can be estimated according to application circuit (see Fig.1):
.
A heatsink is needed at Rth j-mb < 5 K/W and Rth mb-h = 0.5 K/W (using silicon grease) with
Rth h-a = 22.2 K/W − (5 + 0.5) K/W = 16.7 K/W.
