Mini low-voltage protection device fits networking apps


Semtech's RClamp3304N is a 3.3-V transient voltage suppression (TVS) protection device with a footprint that's 77% smaller than the industry standard. Replacing up to nine discrete components, the part measures just 2.6 by 2.6 by 0.6 mm.

The RClamp3304N protects up to four low-voltage interfaces against electro-static discharge (ESD), cable discharge events, and lightning. It offers protection levels that exceed IEC 61000-4-2 ESD specifications. The broad range of applications for this device include integrated connectors, USB ports, Gigabit Ethernet, T1/E1, and T3/E3 interfaces in base stations, central office equipment, routers, hubs, set-top boxes, and servers.

The device has an extremely low clamping voltage for lightning induced peak pulse currents of up to 25 A. The clamping voltage is due in part to a large center tab on the device that serves as a low inductance path to ground for shunting electrical transients away from the protected device.

The lead-free design of the device complies with the European Union’s Restriction on Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive to meet worldwide environmental and regulatory requirements. The RClamp3304N is available immediately in production quantities and is priced at $0.65 each in 1000-piece lots. More information is available at
