TJA1051TK/3/1J

TJA1051TK/3/1J is the HVSON-8 ordering code for the NXP TJA1051 high-speed CAN transceiver, listed word-for-word in the type-number table on NXP’s product page. The /3 in the code is the VIO version: pin 5 is a logic-level supply input, so the transceiver interfaces directly to microcontrollers running from 3 V to 5 V; on the base version that pin is not connected, and on the /E version it is an enable input — the three are not pin-compatible substitutes. Verified figures for this code: supply of 4.5 V to 5.5 V, timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase, compliance with ISO 11898-2:2016, AEC-Q100 qualification, and ±8 kV IEC 61000-4-2 protection on the bus pins, in the leadless HVSON8 package of 3 × 3 mm with improved automated-optical-inspection capability. NXP’s product page already points new designs to the successor TJA1057GTK/3Z, so treat this code as the choice for existing designs and qualified production, and evaluate the successor for a fresh layout. Selection advice: the SOIC-8 sibling TJA1051T/3/1J is also listed in this catalog — the same /3 VIO version in a leaded package; choose between them on assembly process, not on the CAN specification. Parameters verified against the NXP TJA1051 product page and data sheet.
