I²C bus isolation with 5000 Vrms reinforced-grade barrier
The Skyworks SI8602AD-B-ISR is a two-channel digital isolator purpose-built for I²C buses, combining bidirectional and unidirectional channels to isolate the serial clock (SCL) and serial data (SDA) lines while preserving the bus's open-drain architecture. Its 5000 Vrms isolation rating, achieved through capacitive coupling, meets reinforced-grade requirements for galvanic isolation in industrial and medical equipment where the barrier must withstand high-voltage transients without breakdown.
35 kV/µs CMTI and wide temperature range for noisy environments
A minimum common-mode transient immunity of 35 kV/µs ensures the isolator rejects fast voltage transients common in motor-drive and inverter-fed systems — the barrier stays transparent to the I²C data even when the ground plane jumps several hundred volts in nanoseconds.
