Refrigerator or freezer compressors mostly feature input power in the range of 100-300 W. The steady
state current is then in the range of 0.5 to 3 A RMS for a 220-240 V mains voltage.
The highest current appears at start-up and can reach up to 4 times the steady state current. Thermal cal-
culations can demonstratethat, as these events last a short time, 6 A devices can be used without any heat
sink. For example, Figure 4 gives the junction temperature increase of an ACST6-7ST without any heat
sink, due to the inrush current which is measured through the start winding of a 1/5 Horse power compres-
sor. It shows that Tj only reaches 72 °C, when coming from a 60 °C ambient temperature, and remains be-
low the maximum allowed temperature (125 °C).
