Example 5. How to determine case tempera-
ture ( Tc ) for the various heat sink configu-
rations at certain air velocity?
What is the allowable Tc for AV60C-048L-
150F10N heat sink configurations at desired air
velocity of 2.0 m/s, and it is operating at a 48 V
line voltage, a 25 A output current, a 40 °C
maximum ambient temperature?
Determine PD ( Fig.24 ) with condition:
VI = 48 V
IO = 10 A
TA = 40 ° C
v = 2.0 m/s (400 ft./min.)
Get: PD = 19 W
Determine TC: TC = (RCA x PD) + TA
Determine the corresponding thermal resis-
tances ( RCA ) from figure 33:
No heat sink: RCA = 3.8 ° C/W
TC = (3.8 x 19) + 40 = 112 ° C
1/4 in. heat sink: RCA = 2.8 ° C/W
TC = (2.8 x 19) + 40 = 93 ° C
1/2 in. heat sink: RCA = 2.0 ° C/W
TC = (2.0 x 19) + 40 = 78 ° C
1 in. heat sink: RCA = 1.2 ° C/W
TC = (1.2 x 19) + 40 = 63 °C
In this configuration, the heat sink would have
to be at least 1/4 in. high so that the power
module does not exceed the maximum case
temperature of 100° C.

Mechanical Considerations
Installation
Although AV60C half-brick converters can be
mounted in any orientation, free air-flowing
must be taken. Normally power components
are always put at the end of the airflow path or
have the separate airflow paths. This can keep
other system equipment cooler and increase
component life spans.
Soldering
AV60C half-brick converters are compatible
with standard wave soldering techniques.
When wave soldering, the converter pins
should be preheated for 20-30 seconds at
110° C, and wave soldered at 260°C for less
than 10 seconds.
When hand soldering, the iron temperature
should be maintained at 425°C and applied to
the converter pins for less than 5 seconds.
Longer exposure can cause internal damage to
the converter. Cleaning can be performed with
cleaning solvent IPA or with water.
MTBF
The MTBF, calculated in accordance with
Bellcore TR-NWT-000332 is 2,000,000 hours.
Obtaining this MTBF in practice is entirely pos-
sible. If the ambient air temperature is expected
to exceed +25°C, then we also advise a
heatsink on the AV60C half-brick series, orient-
ed for the best possible cooling in the air
stream.
ASTEC can supply replacements for converters
from other manufacturers, or offer custom solu-
tions. Please contact the company for details.
