Package and board-fit for 5 kV isolation
The SI82395BD-IS: Surface-mount assembly with standard SOIC-16 footprint — the 7.50 mm body width is the wide-body variant, so the landing pattern differs from the narrower 3.90 mm SOIC-16; verify the PCB footprint matches the wide-body IPC-7351 standard before layout release.
Gate-drive timing and the Miller plateau
Peak output of 4 A with asymmetric sourcing — the 2 A high-side source and 4 A low-side sink mean the device pulls the gate down harder than it charges it, which speeds through the Miller plateau during turn-off and reduces switching loss in the power FET. Propagation delay is 40 ns max (both edges) with a 5.6 ns max pulse-width distortion — the matched tpLH/tpHL keeps the on-time symmetry tight enough for hard-switched half-bridge topologies without dead-time correction in the controller.
Common-mode transient immunity in traction drives
Minimum 35 kV/µs common-mode transient immunity (CMTI) means the output state does not glitch when the isolated ground plane slews at 35 kV/µs — a typical condition in SiC/GaN inverter half-bridges switching 800 V bus in under 20 ns.
Supply rail and output flexibility
Two independent channels with capacitive coupling isolation — each channel can drive a separate half-bridge leg or be paralleled for higher peak current (8 A effective) with the same propagation delay matching.
Regulatory approvals and compliance documentation
Approved by CQC (China), CSA (Canada), UR (UL Recognized, US), and VDE (Germany) — the part carries the four major regional safety marks, so a single BOM position serves global production without country-specific isolator variants. RoHS3 compliant per — no exemption-listed substances; the part is also REACH and UL 1577 compliant as standard for the Skyworks Si8239x family, though the specific REACH certificate is issued per lot upon request.
