Notes:
1. Device must be mounted on a heatsink or plate with both mounting
screws fastened for correct operation.
2. Thermal resistance values indicated above are valid for assemblies
using thermal paste Electrolube HTS or thermal pad Graftech HT010A,
i.e., Rth
turer should be consulted for selection of appropriate heatsinking.
Specifications are subject to change without notice (28.02.2007)
