NOTES:

2. Most surface mount devices are available on tape and reel; add

“-T” to suffix.

3. Intersil Pb-free products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-Free products are MSL

classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J Std-020B.

* Pb-free Parts Coming Soon.
