Its 5000 Vrms isolation voltage covers reinforced isolation requirements in traction inverters, battery management systems, and on-board chargers where galvanic separation between the high-voltage domain and the low-voltage control logic is mandatory. The 40 kV/µs common-mode transient immunity (CMTI) ensures the data link stays intact during fast-switching events from IGBT or SiC MOSFET stages — a spec that directly determines bit-error rate in noisy motor-drive environments.
Channel count and direction — why 3/1 matters
With three channels on side 1 and one on side 2, this part maps cleanly to isolated SPI (SCLK, MOSI, CS forward; MISO reverse) or to a CAN FD interface where TX, RX, and a wake signal cross the barrier. The unidirectional channel type means each channel drives in one direction only — no bidirectional data lines without external direction control.
