That is a small, low-profile surface-mount package that saves board space compared to the traditional SOIC-8 footprint used on older CAN transceivers. The trade-off is that the SOT-23-8 has a higher thermal resistance than SOIC-8, so the 150°C junction rating becomes the practical limit — keep the ambient temperature and self-heating within the SOA. For a typical 5 V, 50 mA load the junction rise is modest, but if you are driving a heavily loaded bus or operating near 150°C ambient, a quick thermal check is warranted. The TCAN1044AVDDFRQ1 is listed with an active product status. For a production BOM line, this part does not carry the obsolescence risk that legacy 1 Mbps CAN transceivers (like the SN65HVD230 or TJA1050) now face.","metaTitle":"TCAN1044AVDDFRQ1 CAN Transceiver, 8 Mbps, AEC-Q100, SOT-23-8","metaDescription":"TI TCAN1044AVDDFRQ1 automotive CAN transceiver, 8 Mbps data rate, half-duplex, 4.5-5.5V supply, 200 mV hysteresis, -40 to 150°C.
