PCN# Implementation Date Alert Category Title (Abbreviated) Description Summary
PCN-2062 April 22, 2012 Discrete Semiconductors Qualification of Additional Wafer Source and Additional Top Metal Wafer Process Additional, equivalent wafer fab and fabrication processes have been established and qualified to ensure continuity of supply.
  • For select part numbers in PowerDI®123, PowerDI®5, SMA packages (see table 1):
    • Qualification of CSMC in addition to the currently qualified wafer fabrication sources
    • Qualification of an additional solderable top metal process at the current wafer fabrication site, Diodes internal Oldham Fab (OFAB)
  • For select part numbers in TO-220AB packages (see table 2):
    • Qualification of an additional solderable top metal process at the current wafer fabrication site, Diodes internal Oldham Fab (OFAB)

    Affected products are listed in the attached tables.

    Full electrical characterization and high reliability testing has been completed on representative parts to ensure no change to device functionality or data sheet electrical specifications.

    There is no change to Form, Fit, or Function of affected products.

PCN-2070 April 9, 2012 Discrete Semiconductors Qualification of "Diodes Technology (Cheng Du) Company Limited" (DTC) as an Additional Assembly & Test Site for SOT-23 Packaged Parts and Conversion to Copper Bond Wire on Select Discrete Products at Diodes SKE/DSH (Shanghai Kaihong Electronic Co./Diodes Inc. Shanghai) This PCN is being issued to notify customers that in order to assure continuity of supply, Diodes has qualified "Diodes Technology (Cheng Du) Company Limited" (DTC) located in the Chengdu Hi-Tech Industrial Development Zone (CDHT) in Chengdu, China as an additional Assembly & Test Site for select SOT-23 packaged parts using Copper bond wire.

Established in December 2010, as a joint venture between Diodes Incorporated and Chengdu Ya Guang Electronic Company Limited, Diodes Technology (Chengdu) Company Limited (DTC) was formed to perform semiconductor manufacturing assembly and test functions, and is an expansion of the Company's existing manufacturing presence in China. Ramp to high volume production began in May of 2011.

In addition, for part numbers marked with (*) in Table 1, Diodes has qualified Copper bond wire at Diodes SKE/DSH (Shanghai Kaihong Electronic Co./Diodes Inc. Shanghai) Assembly & Test Sites.

Full electrical characterization and high reliability testing has been completed on representative part numbers built using Copper bond wire to ensure there is no change to device functionality or electrical specifications in the datasheet.

PCN-2072 April 12, 2012 Analog Semiconductors Conversion to Copper Bond Wire on Selected Analog Products This PCN is being issued to notify customers that Diodes is in the process of qualifying Copper bond wire for the part numbers listed in this PCN. In order to accommodate the Copper bond wire, the top metal thickness in the die on selected devices has been increased. Part numbers with increased top metal thickness are identified in Table 1 with the following criteria:

* Top metal thickness is increased from 0.8μm to 1.8μm.
** Top metal thickness is increased from 1.5μm to 3.0μm.
*** Top metal thickness is increased from 0.8μm to 2.0μm.

Full electrical characterization and high reliability testing will be completed using representative devices built with Copper bond wire and the increased top metal thickness (if applicable) to ensure there is no change to device functionality or data sheet electrical specifications.

There will be no change to the Form, Fit, or Function of affected products.
