1N4699 BK PBFREE

Overview

The Central Semiconductor Corp 1N4699 BK PBFREE is a silicon Zener diode from the 1N4678 series, designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 12 V with a 5% tolerance range (11.4 V to 12.6 V). The device operates at a test current of 50 μA and dissipates up to 500 mW. It utilizes a DO-35 axial leaded package and supports junction temperatures from -65°C to +200°C.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage characteristics
• Provides stable voltage regulation within a tight 5% tolerance band
• Capable of operation across an extended temperature range suitable for harsh environments

Applications

• Low power voltage reference circuits
• Precision clamping applications
• Protection of sensitive low-current electronic components

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options and environmental compliance status. Ensure the component matches the required DO-35 package dimensions and thermal ratings for your specific design constraints before finalizing procurement.

Selection Notes

Select this component when circuit designs demand minimal quiescent current consumption alongside precise voltage regulation. The low leakage current specification makes it suitable for high-impedance nodes where standard Zener diodes might introduce unacceptable error or power drain.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing common mechanical outlines and electrical testing standards defined in the official datasheet.

Replacement Considerations

Cross-reference with other manufacturers' 1N4699 equivalents ensuring identical 12 V nominal voltage, 500 mW power rating, and DO-35 package compatibility to maintain circuit performance.
