Philips TDA4861

1997 Jan 20 5

Philips Semiconductors 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 Rthj-mb < 5 K/W and Rth mb-h = 0.5 K/W (using silicon grease) with

Rthh-a = 22.2 K/W −(5 + 0.5) K/W = 16.7 K/W.
