TLE6251DST Overview
A CAN transceiver is an interface IC that converts logic-level signals from a CAN controller into differential bus signals and converts received differential bus signals back into logic levels. In the product hierarchy, the TLE6251DST belongs to the CAN transceiver class, then network interface ICs, then interface ICs and semiconductors. Its high operating temperature range of -40°C to +150°C also supports demanding vehicle and industrial environments.
Key characteristics include support for the CAN protocol at up to 1 Mbaud, full-duplex communication, 200 mV receiver hysteresis, and bus wake-up functionality. Bus wake-up allows a low-power node to detect activity on the CAN bus and signal the host controller, helping reduce overall vehicle energy consumption. The 8-pin PG-DSO-8 package also offers a compact footprint for automotive electronics modules.
The TLE6251D is positioned as a high-speed CAN physical-layer interface compatible with ISO 11898-2 and ISO 11898-5, as identified by Infineon's official product page. These references describe CAN physical-layer behavior, while the device itself bridges the digital controller and physical bus. Its 4.75 V to 5.25 V supply range suits regulated 5 V automotive electronics.
Typical uses include powertrain and body-control modules, electric-vehicle control units, industrial automation controllers, robotics, and diagnostic equipment. In each case, the transceiver handles the physical CAN layer while a microcontroller or dedicated CAN controller handles frames, arbitration, error handling, and higher-level protocols.
PCB design must preserve the CAN bus differential symmetry and provide appropriate termination and common-mode behavior. The transceiver's wake-up function should also be evaluated against the host's low-power strategy, because incorrect sleep-mode configuration can prevent remote bus activity from waking the node.
This page consolidates the verified Infineon specifications, distributor availability references, application guidance, and drop-in comparison information into a design-focused component reference. It also distinguishes verified electrical facts from specifications that require confirmation from the manufacturer datasheet.

Typical Applications
TLE6251DST is suitable for 6 applications: Electric Vehicle Control Unit, Body Control Module, Industrial Automation Controller, Robotics Control Network, Automotive Diagnostics Gateway, CAN-Based Sensor Node.
Electric Vehicle Control Unit
The TLE6251DST suits an electric-vehicle control unit that exchanges controller data over a 1 Mbaud CAN network. Its one-transmitter, one-receiver arrangement connects a CAN controller to the physical bus without requiring separate line-driver and receiver ICs. The 4.75 V to 5.25 V operating range fits regulated 5 V vehicle electronics, while 200 mV receiver hysteresis improves tolerance of bus noise. Bus wake-up can reduce the time the node remains awake, although the vehicle's sleep strategy must explicitly enable the wake path.
Recommended
Body Control Module
A body control module can use the TLE6251DST as the physical CAN interface for door, lighting, climate, and body-status nodes. The 1 Mbaud rate is suitable for high-speed CAN communications, and the -40°C to +150°C operating range covers harsh vehicle temperature conditions. The 8-pin PG-DSO-8 package keeps the transceiver compact, but placement must preserve the CAN_H and CAN_L routing symmetry. Wake-up behavior is especially useful in parked vehicles where body modules must sleep without ignoring remote bus activity.
Recommended
Industrial Automation Controller
The TLE6251DST can connect industrial sensors, drives, and remote I/O to a 1 Mbaud CAN controller. Its 200 mV receiver hysteresis helps distinguish valid differential bus levels in electrically noisy equipment, while the 1/1 transmitter-receiver configuration provides a compact physical-layer solution. The 4.75 V to 5.25 V supply range works with regulated 5 V control hardware. Deployment still requires correct bus termination, common-mode grounding, surge protection, and isolation strategy; the component does not replace industrial EMC filtering.
Recommended
Robotics Control Network
In a mobile robot or industrial manipulator, the TLE6251DST provides a 1 Mbaud physical interface for motion commands, status data, and diagnostics. Its full-duplex CAN arrangement allows the host controller to exchange information continuously with remote motor and sensor nodes. The compact 8-pin PG-DSO-8 package supports space-constrained controller boards, and bus wake-up can support systems that periodically sleep. Engineers should still verify cable length, topology, termination, grounding, and protection against motor-switching transients before assuming laboratory performance will carry into production.
Recommended
Automotive Diagnostics Gateway
The TLE6251DST is appropriate for a diagnostics gateway that translates or routes CAN traffic between vehicle network segments. Its 1 Mbaud capability supports standard high-speed CAN, while bus wake-up allows the gateway to react when another node initiates communication. A single transceiver is used per CAN channel, so a multi-channel gateway requires additional devices. The key design checks are 5 V supply tolerance, CAN bus common-mode range, standby-state leakage, fault behavior, and whether the selected part variant satisfies the vehicle's qualification requirements.
Recommended
CAN-Based Sensor Node
A compact industrial sensor node can use the TLE6251DST to publish measurements to a CAN controller at speeds up to 1 Mbaud. The small 8-pin PG-DSO-8 footprint saves board area compared with separate driver and receiver implementations, while 200 mV hysteresis supports reliable interpretation of the differential bus. For battery- or duty-cycled installations, bus wake-up can reduce the need for periodic polling, but quiescent current and wake configuration were not included in the verified data and must be checked before calculating power budget.

Design Notes
Route CAN_H and CAN_L as a closely coupled differential pair with continuous reference over a ground plane. Avoid introducing unmatched stubs, test pads that become unterminated branches, or large copper voids beneath the pair. Place the transceiver close to the connector or protection network to minimize exposed trace length, and observe the manufacturer’s CAN_H and CAN_L layout guidance for the exact PG-DSO-8 footprint.
Provide a regulated 5 V supply within the verified 4.75 V to 5.25 V operating range and follow the manufacturer’s recommended input and bypass-capacitor arrangement. Place the local decoupling capacitor adjacent to the device supply and ground pins. Keep switching-regulator and high-current return paths away from the CAN receive reference to prevent supply noise from appearing as differential bus noise.
Do not assume that every TLE6251 family ordering suffix is automatically interchangeable with TLE6251DST. Confirm package dimensions, exposed-pad requirements, pin functions, standby and wake-up behavior, bus-fault handling, and qualification from the current Infineon datasheet. Likewise, validate a cross-brand SOIC-8 candidate for pin-to-pin function, supply range, common-mode range, and protection before substituting it into an existing PCB.
A CAN bus normally requires correct 120 Ω termination at both ends, but adding termination by habit can be harmful because the transceiver may already include configurable termination. Review the TLE6251DST datasheet and board topology before enabling it. Also ensure that cable shield grounding, common-mode choke selection, and external protection devices do not distort the intended differential signal.
Compliance Information
The supplied snippets identify TLE6251D as an automotive CAN transceiver but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values remain unknown rather than being inferred.
