Semtech Introduces New AEC-Q100 Qualified Protection Array for Automotive CAN Bus Nodes
Expansion of automotive ESD protection platform provides superior protection for CAN buses
CAMARILLO, Calif., Feb. 5, 2019 — Semtech Corporation (Nasdaq: SMTC), a leading supplier of high performance analog and mixed signal semiconductors and advanced algorithms, today introduced a new AEC-Q100 qualified protection array for automotive CAN bus nodes. The new low capacitance 24V (Vrwm) transient voltage protection µClamp® array is optimized to safeguard automotive CAN bus nodes from electrostatic discharge (ESD) and overvoltage transient threats.
“CAN continues to be an important and prolific bus used in today’s automotive system designs,” said Tamir Reshef, Product Marketing Director for Semtech’s Protection Products Group. “The new µClamp2492SQ, with its superior ESD robustness and low clamping voltage performance, provides automotive engineers a much needed solution to safeguard CAN nodes.”
The CAN networking bus has long served as the backbone of vehicle networking and is widely used in today’s vehicles. To adequately provide ESD immunity, CAN nodes require ESD protection devices with 24V working voltage and a low ESD clamping voltage to safeguard bus nodes from the harsh electrical environment in the car. The two-line, 24V µClamp2492SQ offers a low ESD clamping voltage while minimizing loading capacitance, making it suitable for higher speed versions of CAN, including CAN 2.0 and CAN FD.
The µClamp2492SQ is housed in an industry standard SOT-23 3L package, and provides two lines of robust transient protection. The device far exceeds the IEC61000-4-2 ESD immunity standards, offering an industry-leading protection level of ±30kV air and ±30kV contact, and is qualified to Grade 1 of the AEC-Q100 Automotive Standard.
Key Features of µClamp2492SQ
- Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact); IEC 61000-4-4 (EFT) 4kV (5/50ns); IEC 61000-4-5 (Lightning) 5A (8/20μs)
- 24V working voltage protection
- Protects two I/O lines
- Low capacitance (<18pF line-to-line)
- Industry standard SOT-23 package
- AEC-Q100 qualified to Grade 1
