1N4711 BK PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4711 BK PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and low leakage. It features a nominal Zener voltage of 27 V with a 5% tolerance, tested at 50 μA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65 to +200 °C. It utilizes the DO-35 axial leaded package.

Single Zener Diodes Feature Summary

• Designed for applications requiring extremely low operating current (50μA) and low leakage characteristics
• Provides stable voltage regulation with a tight 5% tolerance on Zener voltage
• Capable of operation across an extended temperature range from -65°C to +200°C

Single Zener Diodes Applications

• Low-level voltage reference circuits
• Precision voltage regulation in sensitive electronics
• Protection against overvoltage transients in low-power systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix requirements when purchasing. The 'BK' designation indicates bulk packaging, while 'PBFREE' confirms lead-free plating compliance. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS standards if required by your manufacturing process.

Single Zener Diodes Selection Notes

Select this component for designs prioritizing minimal quiescent current consumption. The 50 μA test current makes it suitable for battery-powered or energy-efficient applications where standard Zener diodes would draw excessive current. Verify that the 500 mW power rating aligns with the thermal management capabilities of the target PCB layout.

Single Zener Diodes 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 similar electrical characteristics optimized for low-current operation. The 1N4711 specifically provides a 27 V nominal breakdown voltage within this lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4711 variants meeting the same 27 V nominal voltage, 500 mW power rating, and DO-35 package constraints. Ensure replacement parts maintain the 50 μA test current specification to preserve low-leakage performance.
