It delivers a 4 A peak output current per channel, enough to drive the gate of a medium-power IGBT or SiC MOSFET directly without a booster stage. With 150 kV/µs common-mode transient immunity, this part holds its output state through fast voltage swings on the isolation barrier — essential in motor-drive or inverter stages where the switching node jumps hundreds of volts in nanoseconds. The 2.5 kVrms isolation rating meets basic insulation requirements for mains-connected equipment; approvals from CQC, CSA, UR, and VDE cover acceptance in North American, European, and Chinese markets. ## Switching performance and timing margins The 19 ns maximum pulse-width distortion keeps PWM duty-cycle errors under one switching period at moderate frequencies. The output stage sources 1.8 A and sinks 4 A — the asymmetry is deliberate: it pulls the gate down faster than it charges it, which helps clamp the gate during turn-off transients. Output supply range spans 6.7 V to 30 V, covering standard gate-drive rails for IGBTs (15 V) and SiC MOSFETs (18-20 V) from a single bias. ## Package and rework reality The body is small enough that a hot-air rework station with a fine nozzle can lift it cleanly; the exposed pad is absent, so no thermal paste or bottom-side preheat is needed. Surface-mount only, supplied in tube. The narrow 0.154-inch body means the pin-1 mark is on the top; verify orientation before placement because the package is symmetric enough to rotate 180° without visual mismatch.","metaTitle":"Skyworks SI8274BB1-IS1 Digital Isolator, 4A Gate Driver","metaDescription":"Skyworks SI8274BB1-IS1 digital isolator with 4A peak output, 2.5kV isolation, 150kV/µs CMTI.
