Frequently Asked Questions
What is the continuous drain current available at 25°C and V=10V?
The continuous drain current is listed as 'I', with a typical value of 3 A.
How should I order this component if I need it in tape and reel format?
Use the entire part number, but add the suffix T to obtain the variant, such as HUF75831SK8T.
What precaution must be taken regarding the absolute maximum ratings?
Stresses above those listed may cause permanent damage; this is only a stress rating, not an operational guarantee.
If I use a copper pad area of 0.0115 in (7.42 mm), what is the associated thermal resistance ($ heta_{JA}$)?
The specified value for $ heta_{JA}$ with that pad size is 189 C/W.
