IR1153S
Electrical Characteristics
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.
