OnChip Devices, Inc. today announced an ultra-low capacitance ESD (Electrostatic Discharge) protection chip to support high-speed data port applications. Available immediately, OnChip's highly integrated ESD0504P solution provides a high-level of ESD protection for interfaces such as USB 3.0, Gbit Ethernet, Firewire, and HDMI. Shipped in very small foot-print UDFN package (1.6mm x 1.6mm x 0.6mm) the ESD0504P offers ultra-low line capacitance to ensure high signal integrity for video formats such as 1080p.

The ESD0504P chip delivers up to 8kV of ESD protection in contact discharge per IEC61000-4-2 standards for up to 4 channels. It also meets the IEC standard 61000-4-4 for EFT (Electrical Fast Transient) and CDE (Cable Discharge Events). With a low clamping voltage of 15V and a low capacitance of less than 1.5pF, the ESD0504P achieves a high level of ESD protection while maintaining signal quality for the latest generation of mobile electronics, with virtually no device degradation.

The ESD0504P is offered in a UDFN 6-Lead package to help PCB designers have flexibility in routing the transient current to the ground. A zener (TVS) diode is embedded between VP and VN to protect the VCC rail against ESD strikes and eliminates the need for a bypass capacitor (which would otherwise be needed for absorbing positive ESD strikes to ground). Furthermore, the chip’s design and its ultra-low line capacitance enables customers to improve time-to-market of their consumer products.

As portable electronics increase in capabilities (while maintaining their small size), ESD devices are becoming more prevalent in protecting passive elements on an IC board. OnChip Devices offers a large range of TVS diode products to minimize the risk of damage to electronic components. A low operating voltage allows for longer battery life, crucial in mobile electronics.

Availability and Pricing
The OnChip ESD0504P ESD protection chip offers 4-channels of ESD protection and is available immediately worldwide at US $0.15 in quantities of 10,000. Developed at OnChip Devices in the Santa Clara state-of-the-art facility, these ESD protection chips are produced to the highest quality standards.
