The 4A peak output current (1.8A source, 4A sink) directly drives the gate capacitance of medium-power IGBTs and SiC MOSFETs without an external booster stage, reducing component count on the gate-drive PCB. ## Switching speed and common-mode transient immunity A minimum common-mode transient immunity (CMTI) of 200kV/µs ensures the output state does not glitch when the ground plane between primary and secondary sides slews at high dv/dt — a critical parameter in motor-drive and switching-power-supply applications where the isolation barrier sees fast voltage transitions during each switching cycle. The pulse-width distortion is specified at 47ns maximum, which sets the minimum on-time the isolator can pass without skewing the duty cycle — relevant for narrow-pulse gate-drive signals in resonant converters. ## Operating range and supply flexibility The output-side supply voltage spans 4.6V to 30V, accommodating both 5V and 12V gate-drive rails as well as 24V industrial bus supplies without an external regulator.","metaTitle":"Skyworks SI8274AB4D-IS1R Digital Isolator, 2.5kVrms, 4A Peak","metaDescription":"Skyworks SI8274AB4D-IS1R digital isolator, 2 channels, 2500Vrms isolation, 4A peak output, 200kV/µs CMTI.
