Thermal Considerations
The HHS60 Series converters are designed for
natural or forced convection cooling. The maximum
allowable output current of the converters is
determined by meeting the derating criteria for all
components used in the converters. For example,
the maximum semiconductor junction temperature is
not allowed to exceed 120 °C to ensure reliable long-
term operation of the converters.
The graphs in Figures 5 thru 8 show the maximum
output current of the HHS60 Series converters at
different ambient temperatures under both natural
and forced convection. (longitudinal airflow direction,
from pin 1 to pin 4).
