Package and board-fit — 8-SOIC, hand-solderable
The SI8711CC-B-IS: No exposed pad to worry about, so the thermal relief is just the usual SOIC land pattern.
What the isolation and transient ratings mean on the bench
Rated for 3750Vrms isolation, this part meets the basic isolation requirement for many industrial and medical applications where the signal path must survive a dielectric withstand test. The capacitive coupling technology keeps the propagation delay tight at 60 ns max — that 60 ns is the time from input edge to output edge, so the system's timing budget needs to account for it on both rising and falling edges. Common-mode transient immunity is specified at 20 kV/µs minimum. In a motor-drive or inverter environment where the ground plane jumps several hundred volts in a microsecond, this isolator will not glitch the output — the 20 kV/µs figure is the slew rate it rejects without corrupting the data.
Active lifecycle and compliance — sourcing posture
Skyworks lists the SI8711CC-B-IS as Active (current production). It is ROHS3 compliant, so it fits into lead-free assembly lines without an exemption. No stock-holding claim — quoted per the buyer's quantity.
