standard bare die devices

Central Semiconductor Corp. has been in the business of manufacturing through-hole discrete semiconductors since 1974. In 1996, Central entered the hybrid market to fill the void left after the departure of several manufacturers from the bare die market.

devices include:

  • diodes
  • rectifiers
  • transistors
  • TVS diodes & ESD protection diodes
  • thyristors

packing options:

  • fully probed wafers (rejects inked)
  • waffle tray packs (100% accepted die)
  • full wafer sawn on plastic ring (rejects inked)

processes & facilities:

  • 100% of die is probed, rejects inked
  • all die inspected in accordance to MIL-STD-750 Method 2073
  • probing performed in Central's Class 1000 clean room
  • majority of Central's die inventory is held in the U.S. at Hauppauge, NY facility

devices are 100% tested and screened

custom services & solutions

Your vision is our mission. Central excels at listening to customers' challenges and designing custom solutions that other manufacturers have no interest in pursuing. Just Ask.

Potential solutions include the following:
