HFBR-2526Z
HFBR-2536Z
Reasons for Changes:
1. Improved mold compound:
to improve moisture sensitivity level from MSL 4 to MSL 3 and to harmonize the mold compound in use.
The improved mold compound has been qualified and used in other Avago products since 2007.
2. New leadframe base material:
to improve the matching of coefficient-of-thermal-expansion. Lead frame layout remains unchanged. All
other 650nm transmitters from Avago have been qualified and shipped with this lead frame material for
more than 15 years.
3. New photodiode:
to qualify alternative photo diode supplier. The alternate supplier and its photo diode is already qualified
and used in other Avago products since 2007.
Effect of Change on Fit, Form, Function, Quality or Reliability:
Reliability qualifications have been performed to ensure product reliability before the implementation date.
Detailed product characterizations were performed to ensure product compliance to datasheet.
