TVS shrinks to less than a quarter the
size
A new 3.3V transient voltage suppression protection device features a footprint that is 77% smaller than the industry standard.
Semtech Corp has announced the RClamp3304N, a 3.3V transient voltage suppression (TVS) protection device with a footprint that is 77% smaller than the industry standard Replacing up to nine discrete components, the RClamp3304N uses exclusive Semtech process technology to achieve full functionality with great clamping performance in a small device

New from Semtech, the SC4820 is a low-power pulsewidth modulator (PWM) controller intended for power conversion using push-pull or bridge topologies.
Linear FET controllers for space-saving PSU design
Semtech has a new family of linear FET controllers that enable simple, space-saving design of distributed single and dual power supplies on primary and peripheral circuit boards.
This design, combined with the company's new leadless SLP packaging, results in a footprint measuring only 2.6 x 2.6mm with an ultralow 0.6mm profile.
The device is the newest member of Semtech's RailClamp family of low-capacitance TVS arrays that protect high-speed data and input/output interfaces from overvoltage situations.
The RClamp3304N protects up to four low-voltage interfaces against electrostatic discharge (ESD), cable discharge events and lightning.

High-density ATE pin-electronics chipset
Semtech has released a new high-performance high-density pin-electronics chipset for use in automated test equipment.
It offers protection levels that exceed IEC61000-4-2 ESD specifications.
The broad range of applications for this device include integrated connectors, USB ports, gigabit Ethernet, T1/E1 and T3/E3 interfaces in basestations, central office equipment, routers, hubs, set-top boxes, and servers, notebook and desktop computers.
"The RClamp3304N highlights Semtech's advanced technology and the real-world size and protection benefits it provides", said Tom Dugan, Semtech's Director of Protection Products.
"The small size and exceptional functionality provided by the RClamp3304N enables designers to provide comprehensive protection for their systems without sacrificing other functionality due to lack of board space".
The device has an extremely low clamping voltage for lightning induced peak pulse currents of up to 25A, providing superior protection for sensitive ICs in high-threat environments.
The superior clamping voltage is due in part to a large centre tab on the device that serves as a low inductance path to ground for shunting electrical transients away from the protected device.
The TVS diodes in the RClamp3304N are constructed using Semtech's proprietary enhanced punch-through diode (EPD) process technology that provides low standoff voltages and enables very low leakage currents and capacitance over traditional silicon avalanche diode processes.
Its low capacitance of less than 5pF makes it well suited for high-speed interfaces.
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.
The part number for ordering the lead-free device is RClamp3304N.TCT.
