ELECTRICAL CHARACTERISTICS
During lightning surge transient voltage across the AC line, over current and over voltage stress are ap-
plied on all the componentsof the power supply.The STIL04 can sustain a maximumpeak surge current of
500Aasdefinedbythecombinewaveformgenerator(8/20μswaveformasshowninfig.A3andA4)
.
Special recommendations for the lightning surge immunity:
1 - Check that the
maximum peak surge current
in the STIL
stays below the limit specified above
.
2 - Check that
no over voltages are applied
on the STIL and the bridge diode.
3 - In order to reduce the dynamic current stress (dI
out
/dt) through the structure of the STIL04, it is recom-
mended to connect a differential mode choke coil in front of the STIL and the bridge diode.
More details and design guidelines are provided in the application note
“AN1600 - STIL: Inrush Current
Limitation Device for Off-Line Power Converter”
