Company record

C3 Semiconductors, LLC designs and manufactures a broad portfolio of power semiconductor components, including TRIACs, silicon controlled rectifiers (SCRs), high‑temperature rectifiers, solid‑state relays, bridge rectifiers and thyristor modules. SCRs are employed for AC switching, while thyristor modules comprise two circuits that can be used individually or as building blocks for power control. Bridge rectifiers and diodes provide 2500 V rms isolation between terminals and the ceramic base. TRIACs are offered in plastic‑tube and bulk packaging, with alternistor and no‑snubber versions for inductive loads and logic‑level versions suitable for microcontrollers and low‑level devices. Solid‑state relays are compatible with OAC type I/O modules. Typical applications span motor control, voltage regulation, welding equipment, low‑frequency freewheel, battery isolation and capacitive‑filter soft‑start. All products are UL listed.
