Product details

Automotive-grade isolation for the BOM

The Texas Instruments ISO7741FQDBQQ1 is a 4-channel, unidirectional digital isolator using capacitive coupling, built to the AEC-Q100 automotive qualification standard. It delivers 5000Vrms galvanic isolation across a 2.25V to 5.5V supply range, with a 100Mbps data rate and propagation delay of 16ns max.

What the 5000Vrms and 85kV/µs CMTI mean for your design

The 5000Vrms isolation voltage is the reinforced-grade rating for mains-connected automotive and industrial systems — it covers the 60-second hipot test required for safety certification in traction drives and on-board chargers. If your gate-driver interface or CAN/SPI isolation path sees >50 kV/µs edges, this part holds the data integrity without bit errors.

Supplied in a 16-SSOP package (3.90mm body width, 0.154" pitch), surface-mount only.

Frequently asked questions

Is ISO7741FQDBQQ1 AEC-Q100 automotive qualified?

Yes, the ISO7741FQDBQQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive applications per the AEC-Q100 stress test standard.

What is the difference between ISO7741FQDBQQ1 and ISO7741FDW?

The key difference is the package: ISO7741FQDBQQ1 comes in a 16-SSOP package (3.90mm width), while the ISO7741FDW uses a 16-SOIC package (7.50mm width). Both are 4-channel unidirectional isolators with the same 5000Vrms isolation, 100Mbps data rate, and AEC-Q100 qualification. The SSOP variant saves board area but requires a different land pattern.
