Product details
Overview
TJA1051TK/3,118 from NXP Semiconductors is a high-speed CAN transceiver implementing ISO 11898-2:2016 and SAE J2284-1 to -5, supporting CAN FD fast-phase data rates up to 5 Mbit/s. It provides differential transmit/receive capability between a microcontroller's CAN controller and the two-wire physical bus, features VIO pin for 3 V–5 V I/O level adaptation, and operates in Normal/Silent modes with zero-bus-load behavior when unpowered. It is AEC-Q100 qualified and used in automotive body control modules.
For engineers reviewing the TJA1051TK/3,118 datasheet, TJA1051TK/3,118 pinout, TJA1051TK/3,118 application, or TJA1051TK/3,118 equivalent, key selection criteria include VIO-supplied I/O compatibility, Silent mode bus isolation, undervoltage detection on VCC/VIO, ±58 V bus fault tolerance, and HVSON8 package thermal performance (Rth(vj-a) = 55 K/W).
Technical Context
The TJA1051TK/3 implements the ISO 11898-2 physical layer with slope-controlled drivers optimized for low EME and high EMI immunity. Its VIO pin enables direct interfacing with 3 V–5 V microcontrollers, decoupling I/O logic levels from VCC (4.5 V–5.5 V), while internal pull-up on TXD and pull-downs on S ensure fail-safe pin states during floating conditions.
It supports two active operating modes: Normal mode (S = LOW) enables full transmit/receive functionality with <250 ns TXD-to-RXD propagation delay; Silent mode (S = HIGH) disables the transmitter while preserving receiver operation and bus recessive state. No Off mode is available-EN pin is exclusive to TJA1051T/E variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC supply | 4.5 V to 5.5 V - powers core transceiver circuitry; undervoltage lockout triggers at 3.5–4.5 V |
| VIO supply | 2.8 V to 5.5 V - sets TXD/RXD/S logic thresholds; enables interoperability with 3 V microcontrollers |
| CAN FD speed | Up to 5 Mbit/s - meets ISO 11898-2:2016 timing requirements for fast-phase communication |
| Bus fault tolerance | ±58 V on CANH/CANL - withstands load-dump and jump-start transients in 12 V/24 V automotive systems |
| ESD protection | ±8 kV HBM on CANH/CANL - exceeds IEC 61000-4-2 Level 4 for robust EMC in harsh environments |
| Thermal resistance | 55 K/W (HVSON8) - enables higher power dissipation in compact layouts vs. SO8 (155 K/W) |
| TXD timeout | 0.3–5 ms dominant time-out - prevents bus lockup by forcing recessive state if TXD remains LOW |
Pinout & Package
HVSON8 package: plastic thermal-enhanced very thin small outline, no leads, 8 terminals, body 3.0 mm × 3.0 mm × 0.85 mm (SOT782-1); exposed center pad connected to GND for enhanced thermal/electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Transmit data input | CMOS-compatible input with internal VIO pull-up; initiates bus dominant/recessive transitions |
| 2 - GND | Ground reference | Digital and analog ground; must be soldered to PCB ground plane; center pad also requires grounding |
| 3 - VCC | Main supply voltage | Powers internal drivers, receivers, and logic; independent of VIO; monitored for undervoltage detection |
| 4 - RXD | Receive data output | CMOS output referenced to VIO; reflects bus state with <65 ns delay from bus recessive edge |
| 5 - VIO | I/O level adapter supply | Sets TXD/RXD/S logic thresholds; allows direct interface with 3 V–5 V microcontrollers |
| 6 - CANL | CAN bus low line | Differential bus terminal; rated for ±58 V; protected against automotive transients and ESD |
| 7 - CANH | CAN bus high line | Differential bus terminal; complements CANL; maintains >1.5 V differential output in dominant state |
| 8 - S | Silent mode control | Active-HIGH input; disables transmitter only; receiver remains active for network monitoring |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2016 compliance | Guarantees interoperability with all HS-CAN FD networks up to 5 Mbit/s without protocol translation |
| VIO-supplied I/O adaptation | Enables direct connection to 3 V microcontrollers without level shifters, reducing BOM count and layout area |
| Silent mode with active receiver | Allows diagnostic monitoring of bus traffic while preventing faulty nodes from disrupting communication |
| Zero-bus-load unpowered state | Eliminates need for external bus termination disable circuitry when VCC is off; improves system safety |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1042TK/3 | Lower ICC (1.5 mA typical in Normal mode), improved ESD (±10 kV), integrated wake-up capability via CAN bus | Supports standby/wake-up use cases; TJA1051TK/3,118 lacks wake-up and has higher current draw | Select TJA1042TK/3 if bus-initiated wake-up is required; otherwise TJA1051TK/3,118 offers cost-optimized Silent-mode-only operation |
| MCP2561FDT-H/SN | SO8 only; no VIO pin (I/O tied to VCC); lower bus fault tolerance (±40 V); not AEC-Q100 qualified | Limited to non-automotive or less demanding 12 V industrial applications; no 3 V MCU support | Choose MCP2561FDT-H/SN for cost-sensitive non-automotive designs where VIO and AEC-Q100 are unnecessary |
Compared with TJA1042TK/3 and MCP2561FDT-H/SN, the TJA1051TK/3,118 delivers optimal balance of Silent-mode reliability, 3 V–5 V MCU compatibility, and AEC-Q100 compliance for cost-constrained automotive nodes without wake-up requirements.

FAQ
What is the function of the VIO pin on the TJA1051TK/3,118?
The VIO pin on the TJA1051TK/3,118 supplies the I/O level adapter circuitry, setting the logic thresholds for TXD, RXD, and S pins. It accepts 2.8 V to 5.5 V, enabling direct interfacing with 3 V microcontrollers without external level shifters. This differs from the TJA1051T variant, where VIO is internally tied to VCC. The TJA1051TK/3,118 uses this pin to maintain signal integrity across mixed-voltage domains.
Does the TJA1051TK/3,118 support CAN FD operation at 5 Mbit/s?
Yes, the TJA1051TK/3,118 is fully compliant with ISO 11898-2:2016 and supports CAN FD fast-phase data rates up to 5 Mbit/s. Its timing parameters-including td(TXD-busdom) ≤ 65 ns and tbit(bus) down to 155 ns-are guaranteed across the full operating temperature range (−40 °C to +150 °C virtual junction). This makes the TJA1051TK/3,118 suitable for high-bandwidth sensor data aggregation in modern automotive networks.
How does Silent mode operate on the TJA1051TK/3,118?
Silent mode on the TJA1051TK/3,118 is activated by applying HIGH to pin S. In this mode, the transmitter driver is disabled, releasing CANH and CANL to recessive state, while the receiver remains fully operational to monitor bus traffic. This prevents a malfunctioning MCU from dominating the bus, enabling safe diagnostics. Unlike TJA1051T/E, the TJA1051TK/3,118 does not support Off mode since it lacks an EN pin.
What package type is used for the TJA1051TK/3,118?
The TJA1051TK/3,118 uses the HVSON8 package (SOT782-1): a leadless, thermally enhanced 3.0 mm × 3.0 mm × 0.85 mm outline with an exposed center pad connected to GND. This package delivers Rth(vj-a) = 55 K/W-nearly 3× better thermal performance than the SO8 variant-making it ideal for space-constrained automotive modules where power dissipation and board area are critical.
Is the TJA1051TK/3,118 qualified for automotive use?
Yes, the TJA1051TK/3,118 is AEC-Q100 qualified (Grade 1), validated for operation from −40 °C to +125 °C ambient (Tvj up to +150 °C). It meets stringent automotive requirements including ±58 V bus fault tolerance, ±8 kV HBM ESD on CANH/CANL, and robust transient immunity per ISO 7637-2. These qualifications confirm its suitability for under-hood and cabin applications in passenger vehicles and commercial trucks.
