BZX85C27

Single Zener Diodes Overview

The BZX85C27 is a silicon unidirectional voltage regulator diode manufactured by Fairchild Semiconductor. It features a nominal Zener voltage of 27 V and a maximum power dissipation of 1.3 W at 25°C. The device utilizes an axial leaded DO-41 glass package with two terminals. It operates within a storage temperature range of -65 to +200 °C and has a maximum junction operating temperature of 200 °C. The component is RoHS compliant, lead-free, and classified under JEDEC DO-41 standards.

Single Zener Diodes Feature Summary

• Axial leaded construction in a glass DO-41 package for through-hole mounting
• Silicon unidirectional voltage regulation functionality
• High thermal stability with a maximum junction temperature of 200 °C

Single Zener Diodes Applications

• Overvoltage protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the BZX85C series is widely produced by multiple vendors including ON Semiconductor and Vishay. Confirm that the procurement matches the original Fairchild specifications regarding tolerance and dynamic impedance if strict adherence to the original datasheet is required. Ensure the package type is correctly identified as DO-41.

Single Zener Diodes Selection Notes

Select this component when a 27 V regulation point is required in a high-power axial configuration. The 1.3 W dissipation rating supports higher current loads compared to smaller SMD zener diodes. Verify that the circuit design accommodates the thermal requirements associated with the DO-41 glass package and the specified maximum junction temperature limits.

Single Zener Diodes Part Context

The BZX85C27 belongs to the BZX85C series of low-power voltage regulator diodes. This series provides a wide range of standardized Zener voltages, typically from 3.3 V to 75 V, with 'C' denoting a 5% tolerance. These components are standard discrete semiconductors used for basic voltage clamping and regulation in electronic assemblies.

Single Zener Diodes Replacement Considerations

Equivalent parts include the ON Semiconductor BZX85C27 and Vishay BZX85C27. Cross-referencing with other manufacturers requires verification of the 1.3 W power rating and DO-41 package compatibility.
