IR1150S/IR1150IS(PbF)
Electrical Characteristics cont.
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage and junction
temperature range TJ from – 25° C to 125°C. Typical values represent the median values, which are related to 25°C. If not
otherwise stated, a supply voltage of VCC =15V is assumed for test condition.
