Propagation delay is 60 ns (tpLH) and 50 ns (tpHL) maximum, with a pulse-width distortion ceiling of 28 ns — the matched delays across channels (this is a single-channel part, but the spec matters for interleaved or multi-phase designs using multiple isolators) keep the dead-time budget predictable. Approvals include CQC, CSA, UR, and VDE, covering the regulatory requirements for safety-isolated gate-drive circuits in industrial and automotive equipment shipped to North America, China, and the EU.","metaTitle":"SI8261BBC-C-ISR Skyworks Digital Isolator, 4A Gate Driver","metaDescription":"Skyworks SI8261BBC-C-ISR digital isolator: 1-channel gate driver, 4A peak, 3750Vrms isolation, AEC-Q100.
