Product details

AEC-Q100 Grade-1 digital isolator for automotive signal chains

The three forward and one reverse channel configuration suits SPI, UART, or CAN FD isolation in ECUs, battery management, and motor-drive interfaces.

85 kV/µs CMTI — the spec that matters for inverter environments

Minimum common-mode transient immunity of 85 kV/µs means this part holds data integrity across fast-switching SiC or IGBT edges typical in traction inverters and DC-DC converters. Propagation delay maxes at 16 ns with 4.9 ns pulse-width distortion, keeping timing margins tight for high-speed control loops.

Frequently asked questions

Is ISO7741FQDBQRQ1 automotive qualified?

Yes, the ISO7741FQDBQRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for production vehicle programs.

How does ISO7741FQDBQRQ1 compare to ISO7741FDBQRQ1?

The ISO7741FDBQRQ1 is the same base device (ISO7741) with identical electrical specs: 4 channels, 100 Mbps, 2500 Vrms, capacitive coupling, and the same package. The key difference is that the FQDBQRQ1 suffix includes AEC-Q100 automotive qualification, while the FDBQRQ1 variant does not carry the automotive series designation. If the BOM requires AEC-Q100, the FQDBQRQ1 is the correct choice.
