TVS Total Volatile Solids (transient-voltage suppressor) protection array, the newest addition to Semtech's RailClamp(R) TVS product family.
The SRV05-4 features ultra-low capacitance of 3pF (typ) per line, which is less than half the capacitance of competing products, permitting communication rates up to 1GHz. The SRV05-4 comes in a space saving SOT-23 6L surface-mount package, occupying less than 1.5mm(2) of board space. The miniature SRV05-4 offers a 5V working voltage and ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine. See ESL. (electrostatic discharge) protection of greater than 15kV.
Utilizing a unique IC process, the SRV05-4 incorporates eight surge-rated, low-capacitance steering devices and an on-chip, avalanche TVS RailClamp(R) in a single package. This array allows users to protect four high-speed data or transmission lines. In the RailClamp(R) configuration, steering devices protect the high-speed I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.
I/O - Input/Output lines while the internal TVS clamps the power line, protecting any downstream components.
The SRV05-4's electrical characteristics are especially well suited to protecting delicate sub-5-volt CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. line transceivers from transients caused by ESD, cable discharge events, lightning and other induced voltage surges.
"Until now, designers have been forced to use inadequate protection schemes due to capacitance constraints," said Tom Dugan, director of marketing for protection products at Semtech. "The SRV05-4 represents an unmatched solution in terms of performance and preservation of signal integrity.
"In fact, we have one customer successfully employing the device on lines running as high as 1.25GHz. This ultra-low capacitance array makes the protection of high-speed interfaces possible and affordable to the engineers working on state-of-the-art telecom and datacom designs."
Applications for the SRV05-4 include:
1. Monitors and flat-panel displays
2. Video graphics cards
3. Cellular phone SIM ports
4. 10/100/1000 Ethernet ports
5. USB USB

The SRV05-4 provides EFT (electrical fast transients) protection to IEC 61000-4-4, protection against lightning strikes to IEC 61000-4-5, and ESD protection to IEC 61000-4-2, level 4 (8kV contact, 15kV air). Peak pulse power, Ppk, is specified as 350W and peak pulse current, Ipp, is 16A (tp = 8/20us). The SRV05-4 operates over a -55 to +125 degrees C temperature range.
Price and Availability
Evaluation samples of the SRV05-4 are currently available, with production volumes now ramping. Pricing begins at $0.48 in production of 10,000 units. The devices are packaged in tape and reel per EIA (Electronic Industries Alliance, Arlington, VA, www.eia.org) A membership organization founded in 1924 as the Radio Manufacturing Association. It sets standards for consumer products and electronic components. 481.
