AEC-Q100 grade-0 CAN transceiver for 5 V automotive buses
The Texas Instruments TCAN1051VDRBTQ1 is an automotive-grade, AEC-Q100 qualified CAN transceiver in a half-duplex configuration with a single driver and single receiver. It supports the CAN protocol at data rates up to 2 Mbps, covering both classical CAN and CAN FD flexible data-rate frames. This covers grade-0 environments — underhood, engine-mount, and transmission-adjacent locations where ambient can spike beyond the typical -40°C floor. The receiver hysteresis of 120 mV provides noise margin on the bus, reducing false bit detection in electrically noisy automotive cabins. The package is an 8-VSON (3x3 mm) with a wettable flank terminal finish. Wettable flanks allow automated optical inspection (AOI) of the solder joint after reflow, a requirement in many automotive Tier-1 assembly lines for zero-defect quality programs. The exposed thermal pad in the VDFN package aids heat transfer to the PCB copper plane.
This means no last-time-buy (LTB) window is open, no end-of-life notification has been issued, and the part remains available for both new production and ongoing series builds. The base product number is TCAN1051, indicating a family with multiple speed and package variants sharing the same core silicon. The OEM auditor will expect to see the AEC-Q100 report and the active lifecycle confirmation in the component PPAP dossier.
Wettable flank package — AOI-ready for automotive assembly
The 8-VSON (3x3 mm) package with wettable flank terminals is designed for surface-mount assembly with automated optical inspection. Wettable flanks require the solder paste to wet up the side of the terminal — standard reflow profiles for SAC305 alloy work with this finish. Mounting type is surface mount with wettable flank — no through-hole or press-fit option exists for this variant.
