UC37133: What is the size of this device and what is the Ron parameter?

Lauren Mayfield

Part Number: UC37133

Maybe I'm missing this in the datasheet but I wasn't able to find it. What is the size (mmxmm) and what is the Ron spec for this device?

Lauren,

The package is a SOIC(D) package and those dimensions can be found at:

Since the power switch is based on BJTs there isn't going to be an emphatic Ron, however the relevant thermal parameters can be derived from the Saturation Voltage parameters listed under the electrical characteristics table in the datasheet.
