The TJA1051 is a high-speed CAN transceiver compliant with ISO 11898-2:2016, supporting CAN FD data rates up to 5 Mbps with a VIO logic interface for 3.3 V / 5 V controllers.
Product Overview
The TJA1051 family describes a widely used 5 V high-speed CAN transceiver standard with a VIO pin that sets the logic interface level to match 3.3 V or 5 V CAN controllers. It offers very low electromagnetic emission, a silent (listen-only) mode, and an automotive temperature range, making it well suited to modern vehicle and industrial CAN FD networks.
Newfly supplies verified, RoHS-compliant TJA1051-class transceivers with cross-reference and BOM-matching support for your supply chain.

FAQ
Q: Does the TJA1051 support CAN FD?
A: Yes. It is CAN FD ready with data-phase rates up to 5 Mbps. Confirm the exact speed grade with the manufacturer datasheet.
Q: What does the VIO pin do?
A: VIO sets the logic-level interface to match your CAN controller (3.3 V or 5 V), improving compatibility across mixed-voltage designs.
Q: Is it suitable for automotive use?
A: Yes. It is specified for an automotive temperature range (-40°C to +150°C) and very low EME.
