1N4710 BK PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4710 BK PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and low leakage. It operates within the 1N4678 through 1N4717 series, featuring a nominal Zener voltage of 25V with a 5% tolerance range from 23.75V to 26.25V at a test current of 50μA. The device dissipates up to 500mW and maintains a maximum reverse leakage current of 0.01μA at 19V. It supports a maximum regulator current of 9.5mA and functions across a junction temperature range of -65°C to +200°C in a DO-35 case.

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'BK' bulk packaging designation and 'PBFREE' lead-free plating suffix as required by the design specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before finalizing procurement orders to ensure adherence to environmental regulations.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand very low bias currents, specifically around 50μA, alongside stable voltage regulation. Ensure the application voltage does not exceed the 500mW power dissipation limit and verify that the DO-35 axial package fits the available board space constraints.

Single Zener Diodes Part Context

This component belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. These devices are characterized by their ability to maintain stable voltage regulation at microampere current levels, distinguishing them from standard high-power Zener variants.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4710 equivalents meeting the same 25V nominal voltage, 500mW power rating, and DO-35 package outline. Verify electrical parameters such as leakage current and test current match the original specifications.

Single Zener Diodes FAQ

What is the maximum reverse leakage current specified for the 1N4710?

The maximum reverse leakage current is 0.01μA measured at 19V.

Does the 'PBFREE' suffix indicate a change in electrical function?

No, the 'PBFREE' suffix indicates lead-free plating options and does not alter the electrical characteristics or function of the device.
