Summary:The CN646, CN647, and CN648, general purpose diodes in the DO-41SP case are discontinued and now classified as End of Life
(EOL).
Although Central Semiconductor Corp. makes every effort to continue to produce devices that have been proclaimed EOL (End of Life) by
various manufacturers, it is an accepted industry practice to discontinue certain devices when customer demand falls below a minimum
level of sustainability. Accordingly, the following product(s) have been transitioned to End of Life status as part of Central's
Product Management Process. Any replacement product will be noted below. The effective date for placing the last purchase order will
be six(6) months from the date of this notice and twelve(12) months from the notice date for final shipments; this may be extended if
inventory is available.
