DD350N14 Infineon - BRIDGE RECTIFIER
DD350N14 Description
The DD350N14 from Infineon Technologies (formerly Eupec) is a rectifier bridge with a 1400 V / 350 A rating. It is used in input rectifiers, freewheeling and clamping circuits, battery chargers and welding power sources. Production of many older modules has ended, but we keep sourcing them for repair and maintenance customers.
Request a quote for the DD350N14 and our team will get back to you with price, quantity available and lead time. We ship worldwide. As with any power device, please check the manufacturer's datasheet to confirm it matches your design.
Target Applications
Infineon DD350N14 is used for AC/DC power conversion and control: controlled and uncontrolled rectifiers, DC motor drives, soft starters, battery chargers, welding equipment, heater and temperature control, and AC power controllers.
