SI823H5BB-AS1R

Isolators - Gate Drivers Overview

The SI823H5BB-AS1R is a dual-channel isolated gate driver from the Skyworks Si823Hx series. It provides high-speed signal transmission via capacitive coupling with a 2.5 kVrms isolation voltage rating. The device operates within a supply voltage range of 3 V to 5.5 V and supports junction temperatures from -40°C to +125°C. Key electrical characteristics include a maximum propagation delay of 30 ns, with rise and fall times of 12 ns each. It is packaged in a DFN-14 form factor and supplied in a reel configuration for automated assembly.
