OnChip Devices Introduces Low Capacitance Diode Arrays for RF Antenna ESD Protection
Packaged in miniature 3-pin SOT23 these ESD diodes are specifically designed to provide contact discharge protection for RF Antennas at levels as high as 8kV when tested to IEC61000-4-2 International Standards
Santa Clara, CA – OnChip Devices, a world leader in Integrated Passive Devices (IPD), has introduced a miniature diode array with very low input capacitance and high protection levels from electrostatic discharge (ESD) for RF Antennas. Wireless devices can be susceptible to ESD events through the Antenna. The ESD pulse can be introduced directly into the RF Switch and Amplifier Circuit. Without sufficient protection, these ICs can be rendered inoperable since they are routinely manufactured using sub-micron technologies. These small geometries are extremely sensitive to ESD. The OC1214-01TR consists of a set of 5 diodes that combine to safely dissipate ESD strikes of ±8kV contact discharge per the stringent requirements of the IEC 61000-4-2 international standard. Despite the exceptionally high ESD level, these devices exhibit a very low input capacitance of under 1pF, thereby preventing signal degradation for the high-speed lines.
OnChip’s new RF Antenna protection diodes are designed for applications requiring signal swing above and below ground with a maximum working voltage of up to ±7V. Battery-powered portable consumer electronics will greatly benefit from these diodes as they have extremely low leakage currents – down to 0.1uA (at 5V). With data serialization, higher bit rates, and increasing screen resolutions, today’s consumer products require uncompromising levels of protection against ESD with ultra-low line capacitance to preserve signal integrity. Protecting these systems with OnChip’s silicon based diodes has become an essential part of the product’s reliability.
“Protecting the RF Antenna circuit in mobile electronics offer many challenges to the designer engineers. The ESD Protection Diodes have to handle bi-directional signals while maintaining very low loading capacitance and clamp voltage. The OC1214-01TR diodes offer a perfect solution by addressing all these issues.” said Ashok Chalaka, President & CEO. “OnChip is already shipping ESD diode array ESD2100 for the USB and HDMI ports and OC1214-02MR for the Ethernet port protection. We are pleased to add the RF Antenna protection circuit to our ever expanding product portfolio.” OnChip has been making new product announcements at the rate of one per month over the past year and a half. Like all diode arrays offered by OnChip, the OC1214 protects against multiple ESD strikes without degradation in product effectiveness.
