Use of the above model permits junction to lead thermal resistance for
any mounting configuration to be found. Lowest values occur when one
side of the rectifier is brought as close as possible to the heat sink as
shown below. Terms in the model signify:
T
A
= Ambient Temperature
T
L
= Lead Temperature
R
S
= Thermal Resistance, Heat Sink to Ambient
R
L
= Thermal Resistance, Lead to Heat Sink
R
J
= Thermal Resistance, Junction to Case
P
F
= Power Dissipation
(Subscripts A and K refer to anode and cathode sides, respectively.)
Values for thermal resistance components are:
R
L
= 40
°
C/W/in. Typically and 44
°
C/W/in Maximum.
R
J
= 2
°
C/W typically and 4
°
C/W Maximum.
Since R
J
is so low, measurements of the case temperature, T
C
, will be
approximately equal to junction temperature in practical lead mounted
applications. When used as a 60 Hz rectifierm the slow thermal response
holds T
J(PK)
close to T
J(AVG)
. Therefore maximum lead temperature may
be found from: T
L
= 175

F
may be found from Figure 7.
The recommended method of mounting to a P.C. board is shown on the
sketch, where R
JA
is approximately 25
°
C/W for a 11/2" x 11/2" copper
surface area. Values of 40
°
C/W are typical for mounting to terminal strips
or P.C. boards where available surface area is small.
