00 — Overview

What the TJA1051T family does

The TJA1051x is a high-speed CAN transceiver interfacing a controller to the physical two-wire bus for automotive applications. It supports data rates up to 5Mbit/s in the CAN FD fast phase and operates across 12V and 24V systems. Variants include the TJA1051T, TJA1051T/3, TJA1051T/E, and TJA1051TK/3, available in SO8 or HVSON8 packages. Key parameters include a supply voltage range of 4.5 to 5.5V, a virtual junction temperature span from -40 to +150°C, and ESD ratings of ±8kV. The device features low supply current in silent mode, typically 0.1mA, and handles bus transients effectively. It is ideal for HS-CAN networks where nodes do not require standby wake-up capabilities, ensuring reliable communication in harsh automotive environments.
