TJA1051T/E/1J - 5Mbit/s CAN Transceiver | NXP Semiconductors
N.º da peça: TJA1051T/E/1J ✓ AtivoTJA1051T/E/1J Visão geral
A CAN transceiver is an interface IC within the broader hierarchy of CAN interface ICs, network interface devices, interface integrated circuits, and semiconductors. It converts logic-level TXD and RXD signals from a CAN controller into the balanced differential signaling used on a CAN bus, while converting received bus levels back into a controller-compatible RXD signal. The TJA1051T/E/1J is intended for high-speed CAN systems in automotive and industrial environments.
The verified product information identifies support for data rates up to 5Mbit/s, Silent mode, and Off mode. Silent mode can place a node into a state that does not actively drive the bus while retaining the ability to receive according to the device behavior. Off mode provides a very low-current shutdown state. The TJA1051T/E family is also identified as backwards compatible with the TJA1050, which is important for designs migrating from that established high-speed CAN transceiver.
The TJA1051T/E/1J is the SOIC-8 version of the third-generation TJA1051 family. NXP describes the TJA1051 as a high-speed CAN transceiver for automotive applications with enhanced electromagnetic compatibility and electrostatic-discharge protection. The differential bus interface reduces susceptibility to common-mode noise, while the transceiver's transmit and receive stages provide the physical signaling required for reliable communication over long, multiconductor harnesses.
Typical uses include automotive body-control modules, powertrain controllers, instrument clusters, electronic control units, industrial automation equipment, robotics controllers, and CAN-based sensors. A CAN controller supplies the TXD input and receives RXD, while the TJA1051T/E/1J connects those digital signals to the CANH and CANL bus conductors. The bus must also include the appropriate termination network, decoupling, and protection arrangement specified by the manufacturer.
A critical design consideration is the difference between TJA1051T/E/1J and TJA1051T/3/1J. The verified NXP information specifically associates direct interfacing with 3V microcontrollers with the TJA1051T/3 and TJA1051TK/3 variants, not the standard TJA1051T/E/1J. The enable and logic-level behavior should therefore be checked against the controller supply voltage and the existing PCB before substitution.
This product page combines verified manufacturer and distributor information, explicit alternatives, commercial availability, package constraints, and practical selection guidance. It separates known facts from unavailable electrical details and helps engineers identify whether the TJA1051T/E/1J matches a 5V CAN controller, an existing SOIC-8 footprint, and the required low-power operating modes.

Aplicações típicas
TJA1051T/E/1J é adequado para 6 aplicaçãos: Automotive Body Control Modules, Industrial Automation and Robotics, Automotive Infotainment and Cluster Modules, Powertrain and Chassis Electronic Control Units, CAN-Based Sensor and Diagnostic Equipment, Embedded CAN Communication Modules.
Automotive Body Control Modules
The TJA1051T/E/1J fits automotive body-control modules because it provides a differential interface between a CAN controller and the vehicle's two-wire CAN network, with operation verified up to 5Mbit/s. Its Silent and Off modes let a node reduce bus activity during diagnostic or sleep conditions. The 8-pin SOIC format fits established controller-board layouts, while the manufacturer's third-generation TJA1051 positioning emphasizes EMC and ESD robustness for electrically demanding vehicle networks.
Recomendado
Industrial Automation and Robotics
The TJA1051T/E/1J is suitable for industrial automation nodes that exchange controller commands and sensor data over a CAN bus. Differential signaling helps reject common-mode noise encountered near motors, relays, and switching equipment, and the verified 5Mbit/s capability supports high-speed control traffic. Normal, Silent, and Off operating states also provide options for active communication, reduced participation, and low-current shutdown. The CAN termination and transceiver placement should follow the NXP reference implementation.
Recomendado
Automotive Infotainment and Cluster Modules
A vehicle infotainment or instrument-cluster module can use the TJA1051T/E/1J to connect its CAN controller to the wider vehicle network. The transceiver's differential bus interface supports reliable communication over the harness, while the verified 5Mbit/s rate covers high-throughput vehicle message traffic. Silent mode is useful when a node should stop actively driving the bus, and Off mode supports a very low-current state. Logic-level compatibility with the chosen processor must be verified before layout release.
Recomendado
Powertrain and Chassis Electronic Control Units
The TJA1051T/E/1J can serve as the physical CAN interface in powertrain or chassis electronic control units where communication reliability is essential. Its third-generation TJA1051 family is identified for automotive high-speed CAN applications and provides enhanced EMC and ESD protection characteristics. The differential transmit and receive paths interface the controller to CANH and CANL, while Off mode can reduce consumption during controlled shutdown. Qualification temperature range and any AEC-Q100 requirement must be confirmed from the exact ordering information.
Recomendado
CAN-Based Sensor and Diagnostic Equipment
The TJA1051T/E/1J is useful in diagnostic tools, test fixtures, and CAN-based sensor interfaces that need a robust link between test equipment and a controller. Its 5Mbit/s capability allows operation with a high-speed CAN network, while Silent mode permits a node to monitor without causing dominant-state bus errors. Off mode is valuable for compact or battery-operated instruments because it enables a very low-current shutdown state. Designers should confirm RXD signaling, supply levels, and isolation requirements before final circuit selection.
Recomendado
Embedded CAN Communication Modules
Embedded communication modules can use the TJA1051T/E/1J as the physical-layer element beside a microcontroller-based CAN controller. The target provides the expected high-speed differential CAN interface in an 8-pin SOIC package, simplifying migration from established TJA1050 and TJA1051 designs. Its Off mode is useful when the host system needs a low-current state, whereas Silent mode supports bus monitoring. The controller's TXD and RXD logic levels, bus termination, and decoupling must be verified using the official NXP data sheet.

Notas de projeto
Place the TJA1051T/E/1J close to the CANH and CANL board connector or transceiver interface, and keep the CAN traces short, symmetrical, and continuous over a common ground reference. Avoid routing the differential pair beneath unrelated switching or high-current paths. The device couples the logic interface to a physically sensitive bus, so connector protection and transceiver placement should follow the NXP application guidance rather than be treated as a separate protection-only section.
Use the supply-bypassing and decoupling arrangement specified by NXP, placing the required capacitors close to the transceiver's supply and ground pins. Validate that the controller's TXD and RXD levels are compatible with this standard TJA1051T/E variant. NXP specifically identifies the TJA1051T/3 and TJA1051TK/3 variants for direct interfacing with supply voltages down to 3V, so a 3.3V controller should not use this part without threshold verification.
Do not treat the E suffix as cosmetic: the verified NXP data sheet associates TJA1051T/E with a very low-current Off mode, and its enable truth table may differ from TJA1051T/1J. Likewise, do not substitute a /3 variant merely because it has the same package. Check pin functions, mode-control states, supply range, and controller logic levels against the exact replacement data sheet before releasing a PCB.
Confirm CAN termination placement according to the physical network topology rather than adding fixed termination at every node. Typical CAN networks place termination at the two physical ends, while unterminated stubs increase reflections. The transceiver's differential signaling helps with common-mode rejection, but it does not remove the need for correct topology, a suitable common-mode range, and appropriately rated bus protection.
