OnChip Devices announces the expansion of its Zener diodes, increasing package options to include common discrete parts. Zener diodes are implemented to protect valuable circuit elements from being destroyed by harmful voltage surges resulting from electrostatic discharge. Ranging from 2V to 100V, these Zeners can be used for voltage regulation in a variety of applications such as consumer electronics, military, communications, LED, and automotive industries. These Zener diodes are available in axial, MELF, and plastic surface mount packages that are Pb-free and comply with the RoHS directive.

These Zeners are available with tolerances of +/- 1% 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. The 1N47 glass diodes have low Zener impedance and provide power dissipation of 1000mW in an axial JEDEC DO-41 package. The ZM47 series provides the same electrical characteristics of the 1N47 series in a glass case MELF package. The BZX55C glass diode series have low leakage current of 0.1uA and a low regulation factor, which ensures the input current through the diode does not deviate noticeably from the output current. The BZV55C series is electrically equivalent to the BZX55C series, but comes in a mini MELF package instead of an axial JEDEC DO-35 package. The BZX84C series is offered in the standard SOT23-3 package. This package is good for automated pick and place assembly for mass produced PC boards. The BZX84C series also has low reverse current, ideal for low voltage applications. 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.
