5 V TVS Protection Device Safeguards High-Speed Automotive Interfaces

Semtech Corp. announced the RClamp0531TQ, a high-performance, ultra-low capacitance transient voltage suppression (TVS) device.

The single-line, automotive-qualified RClamp0531TQ offers unparalleled low-clamping voltage performance, an essential requirement for safeguarding the sensitive electronics common in today's automotive infotainment and telematics systems.

Built on Semtech's highly differentiated process technologies that achieve the industry's lowest clamping voltages, the RClamp0531TQ delivers optimal transient protection.   This low-clamping voltage protection performance is critical in an automotive industry where maximum ESD protection margin is needed.

Providing the highest confidence in automotive component reliability, the RClamp0531TQ device is qualified to grade 1 of the AEC-Q100 automotive reliability standard.  As a single-line device, the RClamp0531TQ is housed in a small 1.0mm x 0.6mm package, giving designers added flexibility in optimizing their circuit board layout.


 ·    Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±20kV (air), ±12kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (lightning) 4A (8/20µs)

·      5 V working voltage protection

·      Protects 1 I/O line

·      Low capacitance (<0.5pF line-to-line)

·      Ultra-small 1.0 mm x 0.6 mm package

·      Pb Free and RoHS/WEEE compliant

The RClamp0531TQ (order code: RClamp0531TQTCT) is available immediately in production quantities and is priced at $0.36 each in 3,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support.
