1N4760A BK PBFREE

Overview

The 1N4760A BK PBFREE is a unidirectional voltage regulator diode manufactured by Central Semiconductor Corp. It features a nominal reference voltage of 68 V and a maximum power dissipation of 1 W. The device utilizes silicon Zener technology in a DO-41 axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a test current of 3.7 mA, and a maximum dynamic impedance of 150 Ω. The component operates within a temperature range of -65°C to +200°C.

Feature Summary

• Provides stable voltage regulation using silicon Zener technology
• Designed for high-temperature operation up to 200°C
• Offers low leakage current for efficient circuit protection

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection systems
• Reference voltage sources

Procurement Notes

Verify the specific manufacturer source, as the 1N4760A designation is produced by multiple vendors including Continental Device India Limited and STMicroelectronics. Confirm that the Central Semiconductor variant matches the required DO-41 package and electrical tolerances. Ensure RoHS compliance documentation aligns with project requirements before finalizing procurement.

Selection Notes

Select this component when a 68 V unidirectional Zener diode with 1 W power handling is required. The DO-41 axial package suits through-hole mounting applications. Consider the ±5% voltage tolerance and 150 Ω dynamic impedance for precision regulation needs. Verify thermal management capabilities given the wide operating temperature range.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes, widely used for voltage reference and regulation. The BK suffix typically indicates bulk packaging. Central Semiconductor produces this component alongside other discrete semiconductors, maintaining compatibility with industry-standard pinouts and mechanical dimensions for easy integration into existing designs.

Replacement Considerations

Direct parameter-equivalent replacements include the 1N4760A from onsemi or Nexperia. Verify that substitute parts maintain the same 68 V nominal voltage, 1 W power rating, and DO-41 package form factor to ensure mechanical and electrical compatibility.
