1N4714 BK PBFREE

Overview

The Central Semiconductor Corp 1N4714 BK PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It operates within the 1N4678 through 1N4717 series, featuring a nominal Zener voltage of 33V with a 5% tolerance. The device dissipates up to 500mW at 75°C and maintains junction temperatures from -65°C to +200°C. It utilizes a DO-35 case package.

Feature Summary

• Designed for applications requiring extremely low operating current (50μA) and low leakage characteristics.
• Features a 5% voltage tolerance across the specified range.
• Capable of maintaining operation within a wide thermal envelope.

Applications

• Low-level voltage regulation circuits
• Reference voltage sources in sensitive electronics
• Circuits requiring minimal quiescent current consumption

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating options. The 'PBFREE' designation indicates lead-free compliance, while other suffixes may denote different material compositions. Confirm availability directly with Central Semiconductor or authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when circuit design demands low power dissipation combined with precise voltage reference stability. Ensure the required Zener voltage aligns with the 33V nominal specification. Verify that the DO-35 axial leaded package fits the board layout constraints and that the 500mW power rating suffices for the expected thermal environment.

Part Context

This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8V to 43V, all sharing similar electrical profiles optimized for low-current operation and housed in the standard DO-35 glass passivated package.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4714 equivalents in DO-35 packages. Ensure replacement parts match the 33V nominal Zener voltage, 500mW power rating, and low-leakage specifications to maintain circuit performance integrity.
