TLE6251DSXUMA1 - 1Mbit CAN Transceiver | Infineon
MPN: TLE6251DSXUMA1 ✗ סוף ייצורTLE6251DSXUMA1 סקירה
A CAN transceiver is an interface IC within the broader network-interface and communication-semiconductor hierarchy. It bridges a digital CAN controller and the differential CAN_H and CAN_L bus. Unlike a protocol controller, this device does not interpret frames or manage arbitration; it provides the electrical interface required to transmit and receive high-speed CAN messages over a multidrop network.
The TLE6251DS family is identified by Infineon as a high-speed CAN transceiver supporting 1 Mbaud operation. Its interface is compatible with ISO 11898-2 and ISO 11898-5, as stated on the Infineon product page. The 4.75 V to 5.25 V operating range places it on a conventional regulated 5 V logic rail, allowing connection to 5 V automotive and industrial CAN controllers while preserving the voltage range expected by the transceiver.
The TLE6251DSXUMA1 includes a standby mode according to distributor product descriptions. Standby capability is useful when a controller must reduce local activity without immediately removing the physical interface from the design. The ordering code also identifies an automotive-oriented device and an automatic temperature-related variant, although the verified material does not provide the full numeric temperature range, transceiver thresholds, loop-delay limits, or electrical test conditions.
Typical uses include automotive body and comfort networks, industrial automation links, diagnostic equipment, and embedded CAN controllers. The 1 Mbaud rate is suitable for high-speed CAN networks, while the 8-pin surface-mount package supports compact controller boards. System qualification should verify the bus topology, termination strategy, ground reference, decoupling, ESD requirements, and the exact operating-temperature grade.
Designers should use the manufacturer datasheet for the complete pin assignment, truth table, electrical characteristics, and recommended application circuit. In particular, validate CAN bus levels under worst-case bus loading and ensure the selected external components match the reference network. Although obsolete status is reported by DigiKey, a clearly documented manufacturer-recommended or parametric substitute may be preferable for new production.
This page consolidates verified lifecycle information, source links, pricing availability notes, package details, and the documented TLE6251DSXUMA2 substitute. It also distinguishes confirmed specifications from electrical data that still requires the manufacturer datasheet, helping engineers make a defensible sourcing or redesign decision without treating unsupported values as guaranteed specifications.

יישומים טיפוסיים
TLE6251DSXUMA1 מתאים עבור 6 יישוםs: Automotive Body and Comfort Networks, Industrial Automation CAN Links, Vehicle Diagnostic Interfaces, Embedded Controller CAN Communication, Industrial Sensor and Actuator Networking, Communication and Network Equipment Interfaces.
Automotive Body and Comfort Networks
The TLE6251DSXUMA1 fits automotive body and comfort CAN networks because Infineon identifies the TLE6251DS family for automotive use, operating at 1 Mbaud on a regulated 5 V rail. The transceiver provides the physical interface between a CAN controller and differential CAN bus wiring while supporting standby operation. A system designer should confirm the device's exact automotive temperature grade and qualification evidence before production. The verified 4.75 V to 5.25 V supply range is compatible with conventional regulated 5 V automotive electronics, subject to transient and supply-quality requirements.
מומלץ
Industrial Automation CAN Links
The TLE6251DSXUMA1 is suitable for industrial automation equipment that uses a 1 Mbaud CAN physical layer between a controller and distributed field nodes. Its 5 V operating range supports conventional embedded logic rails, and the ISO 11898-2 and ISO 11898-5 compatibility stated by Infineon supports standardized CAN network integration. The board should follow the manufacturer application circuit for bus termination, supply decoupling, common-mode behavior, and protection. Verify the operating-temperature grade and ESD limits before deploying it in factory-floor equipment.
מומלץ
Vehicle Diagnostic Interfaces
The TLE6251DSXUMA1 can serve as the physical-layer element in an automotive diagnostic or test interface because it combines a CAN transmitter and receiver with a documented 1 Mbaud capability. The 8-pin surface-mount package also supports compact controller hardware. A diagnostic engineer must use the family datasheet to confirm the exact pinout, standby-control behavior, and bus fault handling before assigning connector signals. For new diagnostic equipment, TLE6251DSXUMA2 should be reviewed as the documented substitute because the original ordering code is obsolete.
מומלץ
Embedded Controller CAN Communication
The TLE6251DSXUMA1 is appropriate when an embedded controller needs a dedicated 1 Mbaud physical interface to a CAN bus. It isolates the controller's logic-level signaling from the differential bus through the transceiver's transmitter and receiver functions. Its 4.75 V to 5.25 V operating range aligns with a regulated 5 V subsystem and its 8-pin package limits board area. Firmware and hardware teams should confirm wake-up, standby, fault, and timing behavior against the manufacturer datasheet, as those details are not fully exposed in the supplied search records.
מומלץ
Industrial Sensor and Actuator Networking
The TLE6251DSXUMA1 can connect a CAN controller to industrial sensors or actuators distributed over a high-speed CAN bus. The 1 Mbaud rate supports efficient communication among controller nodes, while standby support can reduce activity when local control is not required. Layout should minimize the CANH and CANL loop area, provide the intended bus termination, and route the pair as a controlled differential pair. The design must also validate common-mode limits, ESD requirements, grounding, and the transceiver's exact temperature specifications before field deployment.
מומלץ
Communication and Network Equipment Interfaces
The TLE6251DSXUMA1 is applicable to communication equipment requiring a compact CAN connection for internal control, monitoring, or service functions. Its 1 Mbaud bus rate and 5 V supply operation suit embedded controller subsystems, while the 8-pin package supports compact PCB layouts. Design verification should include worst-case bus timing, node count, cable length, termination, ground offsets, and protection requirements. Because the original component is obsolete and only TLE6251DSXUMA2 is explicitly verified as its substitute, new communication equipment should use the alternate pending complete qualification.

הערות תכנון
Do not treat the word "equivalent" in a distributor cross-reference as proof that every electrical limit is identical. Before substituting TLE6251DSXUMA2 for TLE6251DSXUMA1, compare the complete Infineon datasheet entries for pinout, supply thresholds, bus-dominant and recessive levels, loop delay, receiver timing, standby behavior, temperature grade, and protection ratings. Record the comparison and obtain engineering approval because the original device is obsolete.
Follow the manufacturer's application layout for CANH and CANL. Keep the differential pair continuous with matched geometry, minimize stub branches and vias, and place termination only at the physical ends of the bus. Provide local supply decoupling close to the device and maintain the recommended ground return. Because the verified records do not include a pinout or reference layout, do not assign component locations or connector pin numbers until the official package drawing and application circuit are obtained.
A CAN bus is a long, potentially noisy physical network even though the TLE6251DSXUMA1 supports 1 Mbaud communication. Review bus length, node spacing, termination resistance, common-mode voltage, ground offsets, and external protection devices against the manufacturer specifications. Avoid relying on the digital controller or software to compensate for analog bus-condition violations. The supplied sources do not expose the transceiver's exact common-mode or ESD limits, so those values must come from the datasheet.
Power the transceiver from a regulated rail within the verified 4.75 V to 5.25 V range and verify startup, standby, and bus-active current under the intended temperature and load conditions. Place decoupling capacitors according to the Infineon application circuit rather than generic guidance because ESR, bias, and placement can affect CAN signal integrity. The verified material does not provide current consumption or transient limits, which must be checked before power-budget and automotive qualification sign-off.
מידע על תאימות
The verified sources identify automotive use and automotive ordering information but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance remains unknown pending review of the current Infineon product declaration and quality documents.
