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.–(BUSINESS WIRE)–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
  • Pb-Free and RoHS/WEEE compliant

Availability

The µClamp2492SQ (order code: µClamp2492SQTCT) is available immediately
in production quantities. Semtech offers comprehensive design
assistance, including field- and factory-based support. Data sheets,
volume pricing, and delivery quotes, as well as evaluation kits and
