Product details
Overview
TJA1051T,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, operating from 4.5 V to 5.5 V supply, and qualified to AEC-Q100 for automotive use in 12 V/24 V systems.
For engineers reviewing the TJA1051T,118 datasheet, TJA1051T,118 pinout, TJA1051T,118 application, or TJA1051T,118 equivalent, this transceiver delivers guaranteed timing at 5 Mbit/s, bus fault tolerance to ±58 V, ESD protection of ±8 kV (IEC 61000-4-2), Silent mode control via pin S, and SO8 packaging with SOT96-1 footprint compatibility.
Technical Context
The TJA1051T,118 implements the physical layer of high-speed CAN networks without integrated wake-up capability, distinguishing it from standby-mode transceivers. It features slope-controlled differential drivers for low EME, a differential receiver with 0.7 V threshold and 120 mV hysteresis, and TXD dominant time-out (0.3–5 ms) to prevent bus lockup.
Pin 5 is n.c. (not connected), confirming backward compatibility with TJA1050 and eliminating VIO or EN functionality. Its passive bus disengagement when unpowered ensures zero load on the CAN bus during power-off, and undervoltage detection on VCC (3.5–4.5 V) forces safe bus release under brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Compliance | ISO 11898-2:2016 and SAE J2284-1 to J2284-5 - enables interoperability in automotive HS-CAN FD networks |
| Data Rate | Up to 5 Mbit/s in CAN FD fast phase - supports high-bandwidth ECUs like ADAS controllers and gateway modules |
| Supply Voltage | VCC = 4.5 V to 5.5 V - compatible with standard 5 V automotive power rails and robust against battery transients |
| Bus Fault Tolerance | CANH/CANL withstand ±58 V - survives load dump, jump-start, and inductive switching events in 12 V/24 V systems |
| ESD Protection | ±8 kV HBM and IEC 61000-4-2 on CANH/CANL - eliminates need for external TVS diodes in most automotive PCB layouts |
| Operating Temperature | −40 °C to +150 °C virtual junction temperature - meets under-hood thermal requirements per AEC-Q100 Grade 1 |
| Silent Mode | Controlled by pin S (HIGH = transmitter disabled, receiver active) - allows diagnostic isolation without breaking network communication |
Pinout & Package
Package: SO8 (SOT96-1), plastic small outline package, 8 leads, body width 3.9 mm, lead pitch 1.27 mm, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Transmit Data input | CMOS-level digital input driving bus state; internal pull-up to VIO ensures defined HIGH if floating |
| 2 - GND | Ground reference | Primary signal and power ground; must be low-impedance connection to PCB ground plane |
| 3 - VCC | Main supply voltage | 4.5–5.5 V power rail; undervoltage detection (3.5–4.5 V) triggers automatic bus disengagement |
| 4 - RXD | Receive Data output | CMOS-level digital output reflecting bus state; active in both Normal and Silent modes |
| 5 - n.c. | No connection | Unbonded pad; no internal connection - confirms TJA1051T variant (no VIO or EN function) |
| 6 - CANL | CAN bus low line | Differential bus terminal; rated for −58 V to +58 V; requires 120 Ω termination at network ends |
| 7 - CANH | CAN bus high line | Differential bus terminal; paired with CANL; symmetric driver output ensures <±400 mV Vdom(TX)sym |
| 8 - S | Silent mode control | Active-HIGH enable for Silent mode; internal pull-down ensures Normal mode on power-up if left floating |
Key Features
| Feature | Design Value |
|---|---|
| Zero-bus-load power-off behavior | Bus pins fully disengage when VCC = 0 V - prevents unintended network loading during ECU sleep or battery disconnect |
| Differential receiver hysteresis | 120 mV typical - rejects common-mode noise and prevents chatter near threshold in electrically noisy vehicle environments |
| TXD dominant time-out | 1 ms typical (0.3–5 ms range) - guarantees bus recovery within 5 ms if controller locks TXD LOW, satisfying ISO 11898-2 safety requirement |
| Thermal shutdown protection | Triggers at 190 °C virtual junction temperature - disables drivers until temperature falls and TXD goes recessive, preventing oscillation |
| Input undervoltage detection | Vuvd(VCC) = 4.0 V typical - releases bus before microcontroller resets, avoiding metastable bus states during power ramp-up/down |
Applications

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 |
|---|---|---|---|
| MCP2551-I/P | Legacy 1 Mbps-only transceiver; no CAN FD support; no Silent mode; lower ESD rating (±4 kV) | Suitable only for classical CAN (not CAN FD); lacks TXD time-out and undervoltage detection | Select only for cost-sensitive legacy 1 Mbps networks where FD bandwidth and enhanced fail-safes are unnecessary |
| TJA1042T/3,118 | Includes VIO pin for 3–5 V MCU interfacing; higher ESD (±12 kV); supports partial networking and wake-up via bus | Enables low-power standby with wake-up; required for modern gateways needing selective node activation | Choose when system requires bus-initiated wake-up or mixed-voltage MCU interfacing - not drop-in compatible due to VIO pin function |
Compared with MCP2551-I/P, TJA1051T,118 adds CAN FD readiness, Silent mode, and stronger fault protection; compared with TJA1042T/3,118, it omits wake-up capability but simplifies design by removing VIO dependency and reducing BOM count.

FAQ
What is the maximum data rate supported by the TJA1051T,118?
The TJA1051T,118 supports data rates up to 5 Mbit/s in the CAN FD fast phase, as specified in ISO 11898-2:2016. This timing is guaranteed across its full operating temperature and voltage range, making TJA1051T,118 suitable for high-bandwidth automotive applications such as ADAS sensor fusion and gateway data aggregation.
Does the TJA1051T,118 support Silent mode, and how is it controlled?
Yes, the TJA1051T,118 supports Silent mode, activated by applying a HIGH logic level to pin S (pin 8). In this mode, the transmitter is disabled and bus lines are released to recessive, while the receiver remains fully operational - enabling diagnostics and firmware updates without disrupting the CAN network. The TJA1051T,118 includes an internal pull-down on pin S to default to Normal mode at power-up.
Is the TJA1051T,118 pin-compatible with the older TJA1050?
Yes, the TJA1051T,118 is backward compatible with the TJA1050 in SO8 package (SOT96-1), sharing identical pinout, electrical characteristics, and footprint. This allows direct replacement in existing designs while delivering improved EMC performance, higher ESD tolerance (±8 kV vs. ±6 kV), and extended bus fault tolerance (±58 V).
What protection features does the TJA1051T,118 include for automotive environments?
The TJA1051T,118 integrates multiple automotive-grade protections: ±58 V bus fault tolerance, ±8 kV IEC 61000-4-2 ESD on CANH/CANL, TXD dominant time-out (0.3–5 ms), undervoltage detection on VCC (3.5–4.5 V), and thermal shutdown at 190 °C. These ensure reliable operation during load dump, jump-start, and in-cabin thermal stress - all validated per AEC-Q100.
What is the function of pin 5 on the TJA1051T,118?
Pin 5 on the TJA1051T,118 is n.c. (not connected), confirming it is the base variant without VIO or EN functionality. This distinguishes it from TJA1051T/3 (VIO on pin 5) and TJA1051T/E (EN on pin 5). The n.c. designation ensures compatibility with legacy TJA1050 layouts and eliminates configuration dependencies for 5 V MCU interfaces.
