SI8275GAD-IM1

Isolators - Gate Drivers Overview

The SI8275GAD-IM1 is a single-channel digital isolator gate driver manufactured by Skyworks Solutions. It features a 14-VDFN (5x5 mm) surface-mount package and operates within a temperature range of -40°C to +125°C. The device provides 1 kVrms isolation voltage and supports output supply voltages from 4.2 V to 30 V. Key electrical parameters include a maximum propagation delay of 75 ns, a typical rise time of 10.5 ns, and a typical fall time of 13.3 ns. It delivers peak output currents up to 4 A and exhibits high common-mode transient immunity.
