FOD8480R2

FOD8480R2 Description

The FOD8480R2 from onsemi is a high-performance, single-channel optocoupler gate driver designed for robust isolation in power electronics applications. It features 5kVrms isolation (IEC/EN/DIN, UL certified) and operates with an output supply voltage range of 4.5V to 30V, making it suitable for driving MOSFETs, IGBTs, and other power switches. With a common mode transient immunity (CMTI) of 20kV/µs (min), it ensures reliable operation in noisy environments. The device leverages optical coupling technology for galvanic isolation, offering low propagation delay (300ns max) and minimal pulse width distortion (250ns max). Packaged in a 6-pin SOIC and available in tape & reel (TR), it is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
