Thermal Design
Since the VPS12 has the three-channel configuration shown in the circuit diagram on page 2, we first consider a single
channel. The chip temperatures of the transistors during operation can be determined from the following formula:
Tj = (Tri) = θj-c (Tri) × Pc (Tri) + Tc + Ta (°C) ........................(1)
θj-c (Tri): Thermal resistances of the transistor chips themselves
Pc (Tri): Collector loss of the transistors
Tc: Increase in case temperature
Ta: Ambient temperature
The θj-c (Tri) for the individual transistors is:
θj-c(Tr1) to (Tr4) = 35°C/W .........................................................(2)
Although the loss in each transistor in the video pack changes with frequency and thus are not identical, assuming a
maximum frequency of 120 MHz (clock), the transistor with the largest loss is Tr3 in the emitter-follower stage. From
the Pd-f(clock) figure it can be seen that this loss is 22% of the total loss. Thus:
Pc (EF stage) f = 120 MHz = Pd (1ch) f = 120 MHz × 0.22 [W] .............(3)
Select a θh for the heat sink so that the junction temperature (Tj) of this transistor does not exceed 150°C. Equation (4)
gives the relationship between θh and Tc.
Tc = Pd (TOTAL) × θh ..............................................................(4)
The required θh can be calculated from this equation and equation (1).
