Power Dissipation
The LT6550/LT6551, enhanced
θJA MS package, has
Pin 5 (VEE for the LT6550 and GND for the LT6551) fused
to the lead frame. This thermal connection increases the
efficiency of the PC board as a heat sink. The PCB material
can be very effective at transmitting heat between the pad
area attached to Pin 5 and a ground or power plane layer.
Copper board stiffeners and plated through holes can also
be used to spread the heat generated by the device. Table 1
lists the thermal resistance for several different board
sizes and copper areas. All measurements were taken on
3/32” FR-4 board with 2oz copper. This data can be used
as a rough guideline in estimating thermal resistance. The
thermal resistance for each application will be affected by
thermal interactions with other components as well as
board size and shape.

*Device is mounted on topside.
As an example, calculate the junction temperature for the
circuit in Figure 2 assuming an 85
°Cambienttemperature.
The device dissipation can be found by measuring the
supply current, calculating the total dissipation and then
subtracting the dissipation in the load.
The dissipation for the amplifiers is:
PD = (106mA)(5V) – 4 (2.5V)2/150 = 363mW
The total package power dissipation is 363mW. When a
2500 sq mm PC board with 540 sq mm of 2oz copper on
top and bottom is used, the thermal resistance is
110
°C/W. The junction temperature (TJ) is:
TJ = (363mW)(110°C/W) + 85°C = 125°C
The maximum junction temperature for the LT6551 is
150
°C so the heat sinking capability of the board is
adequate for the application.
