Fairchild Semiconductor part numbers

Fairchild Semiconductor (FDS/FQP MOSFETs, FAN power ICs, FSA switches, FOD optocouplers, NC7 TinyLogic) was acquired by ON Semiconductor (now onsemi) in 2016.

Fairchild Semiconductor is now onsemi (2016). We quote Fairchild Semiconductor parts — current, obsolete and end-of-life — and parts that carry older Fairchild Semiconductor markings. See also all onsemi part numbers.

Frequently asked questions

Is Fairchild Semiconductor still in business?

Fairchild Semiconductor (FDS/FQP MOSFETs, FAN power ICs, FSA switches, FOD optocouplers, NC7 TinyLogic) was acquired by ON Semiconductor (now onsemi) in 2016.

Can I still buy Fairchild Semiconductor parts?

Yes. PartnerSemi quotes Fairchild Semiconductor part numbers, including obsolete and end-of-life parts and parts with old Fairchild Semiconductor markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized Fairchild Semiconductor or onsemi distributor.
