Optimized for High-Speed Buses: Extremely low 12 pF line capacitance minimizes impact on data integrity and signal edge rates of high-speed differential signals such as CAN (up to 1 Mbps), LIN, or FlexRay.
Precise & Reliable Protection: Provides precise 27V standoff and 50V clamping voltage, capable of fast response and absorption of energy from common transients like ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4), protecting downstream sensitive components like CAN transceivers.
Automotive-Grade High Reliability: AEC-Q101 qualified, meeting stringent automotive requirements for extreme temperature, vibration, and long operational life, with an operating temperature up to 150°C.
High Pulse Power Handling: 200W peak pulse power (8/20µs) is sufficient to handle surges common in automotive environments, such as load dump and inductive load switching.
Compact Package: Space-saving SOD-323 surface-mount package facilitates easy integration into space-constrained vehicle ECU modules or communication interface boards.
Automotive Network Bus Protection: Provides reliable ESD and transient overvoltage protection for CAN-H/CAN-L, LIN, FlexRay, and other network communication lines.
In-Vehicle Communication & Infotainment: Protects high-speed data lines such as GPS antenna interfaces, USB data ports, audio inputs, and automotive Ethernet.
Industrial Communication & Automation: Used for protecting industrial fieldbus lines (e.g., CANopen, DeviceNet), RS-485/422 interfaces, and sensor signal lines.
Telecom & Networking Equipment: Protects low-speed control signal lines or RF front-ends in base stations, routers, and switches.
Consumer Electronics Interface Protection: Suitable for various device interfaces requiring high-speed data line protection with high signal quality demands.
The AQ27COM-01FTG is a TVS solution that achieves an excellent balance between signal integrity and protection strength. Its low capacitance makes it an “invisible guardian” for high-speed data lines, while its powerful 200W surge absorption capability and automotive-grade reliability provide a robust safety barrier for the system. Whether in increasingly complex automotive electronic networks or in industrial communications and telecom equipment, this device is a preferred protection component for ensuring the long-term stable and reliable operation of signal interfaces.
