OnChip Devices, a global leader in integrated passive devices, today introduced TVS diodes with what the company calls “the highest electrostatic discharge protection levels.”
Headquartered in Santa Clara, California, OnChip Devices offers state-of-the-art silicon and ceramic solutions for High-brightness LED, Computing and Consumer Electronics.
The ESD TVS diodes packaged in miniature SOT23, SOT143 & SC70 (SMD) are designed to be cost-effective and space-sensitive applications requiring high contact discharge protection. When tested against the maximum requirements of IEC61000-4-2 international standards, the diodes display contact discharge protection as high as 30kV, company officials say. The ESD2200 device is available in 2, 3, 4 and 5 channels and has a relatively low input capacitance of under 20pF which provides EMI filtering when used along with a PCB trace or series resistor, they say.
According to Ashok Chalaka, president and chief executive officer of OnChip Devices, “The introduction of the ESD2200 diodes is another significant highlight in OnChip’s brief history. Within a very short span, we have established ourselves as an industry leader in Integrated Passive Devices. OnChip continues to rapidly increase it’s product portfolio in the ever expanding ESD protection market. We have launched a major product every month since November 2007 and we plan to continue with our aggressive product roadmap.”
Company officials say OnChip ESD2200, developed at the company’s silicon fabrication facility at Santa Clara, adheres to highest quality standards. The production price ranges from 6 cents to 15 cents, depending on the number of channels and the package type, they say. Other products on offer from OnChip include thin film resistors, thin film capacitors, EMI/RFI (

Use of integrated circuits with sub-micron geometrics and low-working voltages in portable devices like mobile handsets, PC/Notebooks, MP3 players, PDA’s etc. leads to ESD failures, according to the company. In order to increase the product’s reliability, silicon based TVS diodes are used, officials say. The ESD2200 offers clamp voltage as low as 10V which enables the elimination of IC latch-up and soft errors, company officials say.
