Use TI TCAN3404-Q1 for each of the three CAN channels.
Why it fits:
- CAN FD: supports data rates up to 8 Mbps
- Automotive qualified: AEC-Q100
- 3.3 V MCU interface: compatible with the STM32H725
- Wide bus fault protection: ±58 V
- Low-power standby mode
- Small VSON package: suitable for the 85 × 50 mm board
Recommended orderable part:
- TCAN3404DRBRQ1
- Package: 8-pin VSON/DRB, 3 × 3 mm
- Quantity: 3
Use one TCAN3404-Q1 per channel, followed by the channel’s common-mode choke and PESD2CAN protection. Verify that the footprint includes the exposed thermal pad and connect it to ground with nearby vias.

I recommend the NXP TJA1044GT/3 for each CAN channel.
- Automotive AEC-Q100
- CAN FD up to 5 Mbit/s
- Designed for direct use with 3.3 V microcontrollers, including STM32H725
- Standby and wake-up support
- SO8 package, easier to assemble than VSON
- Bus fault protection and excellent automotive EMC performance
Use three TJA1044GT/3 transceivers, one per CAN-FD channel. For improved signal integrity on long or highly branched automotive networks, consider the newer NXP TJA1443 CAN SIC transceiver, but it is larger and requires more support/configuration.
