The junction temperature rating of -40°C to 150°C means this transceiver is specified for under-hood and other high-temperature automotive environments where standard commercial-grade parts would fail. ## Supply rail and temperature — the fit decisions The 5V to 18V supply range covers the nominal 12V automotive battery voltage with headroom for load-dump transients. ## Package and layout — 8-HVSON exposed pad The 8-HVSON package measures 3x3 mm with an exposed pad underneath. That pad must be soldered to a PCB thermal land and, ideally, connected to a ground plane via thermal vias to pull heat out of the die. Without that thermal management, the junction temperature will rise faster under load, eating into the 150°C margin. The supplier device package is designated 8-HVSON (3x3), so the footprint matches standard 8-pin DFN patterns with a center pad. ## Lifecycle and sourcing The part is ROHS3 compliant.","metaTitle":"TJA1027TK/20,118 LIN Transceiver, 5V-18V, 8-HVSON","metaDescription":"NXP TJA1027TK/20,118 single LIN bus transceiver in 8-HVSON package.

Its logic-level interface is designed for the LIN protocol controller, typically running at the same supply voltage or a regulated 5V/3.3V domain — but the evidence does not specify the logic-level thresholds, so verify the VIH/VIL against your MCU's I/O voltage in the datasheet."},{"question":"What is the closest pin-compatible alternative to TJA1027TK/20,118?","answer":"The TJA1027 family includes several package and temperature variants (e.g., TJA1027T/20 for the SO-8 package). The TK/20 suffix specifies the 8-HVSON package and the -40°C to 150°C temperature grade. For a pin-compatible alternative, look at other TJA1027 derivatives in the same 8-HVSON footprint — the pinout is consistent across the family, but confirm the temperature grade and supply range match your requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/TJA1027TK-20118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/TJA1027TK-20118 when reusing this data.
