The 5000 Vrms isolation rating is the reinforced-level barrier that meets IEC 60747-5-5 and VDE 0884-10 requirements for basic and reinforced isolation in mains-connected equipment. For a traction inverter or on-board charger, this rating provides the creepage and clearance margin needed for a 600 V DC bus with transient overvoltages. The 85 kV/µs minimum common-mode transient immunity is the critical spec for surviving fast switching events: when a SiC or GaN FET switches at 50 V/ns, the isolator's internal coupling capacitance must reject that common-mode slew without corrupting the data. A CMTI below 50 kV/µs would risk bit errors in a motor-drive application; 85 kV/µs gives comfortable margin.
Channel configuration and timing for the isolation path
The six channels are arranged as four on side 1 and two on side 2, all unidirectional. This 4/2 split suits a typical SPI isolation interface: three channels for SCK, MOSI, and CS, plus one for a status or fault signal on side 1, and two channels for MISO and an interrupt or enable on side 2. The maximum propagation delay of 16 ns and pulse-width distortion of 4.9 ns leave enough timing budget for a 50 MHz SPI clock with a 10 ns setup window at the receiver. Rise and fall times of 1.1 ns and 1.4 ns are fast enough for 100 Mbps signalling but still controlled enough to avoid excessive ringing on a short PCB trace — no external slew-limiting needed for traces under 50 mm.
Supply range and logic-level compatibility
This covers the common logic levels in automotive ECUs: 3.3 V for the MCU and 5 V for the gate-driver or sensor interface. The input thresholds are CMOS/TTL-compatible across the supply range, so no external level translator is needed when crossing a 3.3 V domain to a 5 V domain. The part does not provide isolated power — each side needs its own local supply rail and decoupling.
Package, footprint, and storage notes
The wide-body SOIC-16 provides the creepage distance needed to sustain the 5000 Vrms isolation rating — the narrow-body SOIC-8 or SOIC-14 variants in the same family would not meet the same isolation voltage. The part ships in tube.
Lifecycle and production status
This means the part is in normal production with no announced end-of-life or last-time-buy window. The base product number is ISO7762; the QDWQ1 suffix denotes the automotive-qualified, wide-body SOIC variant.
Sourcing and availability
The active lifecycle means the supply channel is stable, with no LTB or allocation constraints expected for the foreseeable production horizon.
