FREMONT, CA: OnChip Devices, a provider of integrated passive devices, releases new TVS diodes for PC boards that use through hole or surface mount technology. TVS diodes are specifically designed for voltage suppression in a circuit that is susceptible to electromagnetic discharge.

TVS diodes protect various circuit components by redirecting the perilous currents to ground and protect various circuit components by providing a low impedance path for transient current to travel. These TVS diodes range from 5V up to 440V, providing a solution for a variety of projects. Some applications include consumer electronics, military, communications, LED, and the automotive industry. They are available in glass axial packages as well as plastic surface mount packages, and are lead-free and RoHS compliant.

The KE series offers protection from pulse currents up to 140A. It also offers the designer up to 1500W of power dissipation. These are available in DO axial glass packages, with the option of unidirectional or bidirectional signal protection. The plastic package is ideal for mass manufactured board that utilize pick and place automation.

Latest Zener Diodes Now Available
The company also announces the expansion of its Zener diodes to protect valuable circuit elements from being destroyed by harmful voltage surges resulting from electrostatic discharge.  Like TVSs, Zeners can be utilized for voltage regulation in a variety of applications such as consumer electronics, military, communications, LED, and automotive industries.

These Zeners are available with tolerances of +/- 1 percent and leakage current as low as 0.05uA. They are rated for use in high temperature environments up to 200°C. Breakdown voltage and power dissipation are consistent when tested to varying current values, providing the designer with predictable electrical behavior for each specific application.

All of these diodes are designed to function as voltage regulators, providing constant output voltage regardless of the surges of voltage from the power supply or ESD discharge.
