Recommended Pad Layout

Notes

1. JEDEC termination code (e4). Barrier-plating is

nickel [Ni] with gold [Au] flash plate.

2. Reflow conditions per JEDEC J-STD-020; +260°C

maximum, 20 seconds.

3. Due to package variability, the pad chamfer on the

bottom could be located on Pin 1 or Pin 2 in a

given lot. Layout orientation should be based on

the top view [marking side], as indicated in

package drawing. The chamfer location does not

affect the electrical performance of the device.

4. MSL = 1.
