The RClamp0504N is a 5.0V protection device aimed at next-generation monitors, laptops, television set top boxes and networking equipment using high-speed I/O protocols.
New from Semtech, the RClamp0504N is a 5.0V protection device aimed at next-generation monitors, laptops, television set top boxes and networking equipment using high-speed I/O protocols. The RClamp0504N measures a mere 2.0 x 2.0 x 0.6mm. It features an array of surge-rated steering diodes and a low voltage TVS diode and protects up to four data lines.

The device’s low capacitance of 3pF (typical) allows it to operate with no insertion loss to 1GHz.

The advent of USB 2.0, gigabit Ethernet, DVI and other high-speed data protocols has created a greater need for protection from cable discharge events (CDE) - the insertion of a statically charged connector - that can cause a system failure.

The RClamp0504N features a fast response time, low inductance and greater electrostatic discharge (ESD) protection for these applications.

‘CDEs are becoming a huge issue for electronics makers, because without the right protection for higher speed I/O lines, they could see an increase in warranty claims when transient electricity destroys a key component’, said Tom Dugan, Semtech’s Director of Protection Products.

‘The RClamp0504N gives these products the ESD protection they need to alleviate this problem, along with a small form factor that allows designers to be creative with how to protect their systems - by putting the protection in the connector, for example’.

The device is in Semtech’s leadless package design, which is 66% smaller than the leading industry solution.

That small package size is a result of Semtech manufacturing process advances that shrink the semiconductor features and enable the single-die design.

The small size also means the device can be used in USB or Ethernet cable connectors, protecting monitors, laptops and other small systems where board space is at a premium.

RClamp0504N is part of Semtech’s RailClamp protection device family, which includes the SRV05-4.

The SRV05-4 is an established leader in low voltage protection devices.

It had been used in many applications including laptop computers where high-speed ports are prevalent.

The RClamp0504N is designed for next generation designs where the requirement for small form factor is critical.

This device replaces the SRV05-4 where board space is limited.

RClamp0504N is designed to meet the following IEC requirements: IEC61000-4-2 (ESD) +/-15kV (air) and +/-8kV (contact), IEC61000-4-4 (EFT) 40A (5/50ns), and IEC61000-4-5 (lightning) 12A (8/20us).

The lead-free design of the device complies with the European Union’s RoHS Directive to meet worldwide environmental and regulatory requirements.
