1N6018B

Single Zener Diodes Overview

The Fairchild Semiconductor 1N6018B is a silicon Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 56V with a tolerance of 5%. The device is rated for a power dissipation of 0.48W at 25°C. It utilizes a hermetically sealed glass DO-35 axial leaded package, ensuring reliability in harsh environments. The component operates unidirectionally and is constructed using planar silicon technology.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• Planar silicon design for stable voltage regulation
• Axial leaded package suitable for through-hole mounting

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as Microsemi (now Microchip) holds rights to the 1N6018B designation. Confirm RoHS compliance status, as historical data indicates non-compliance for some variants. Ensure the DO-35 package matches the required form factor. Check for any suffix variations that may indicate different tolerance levels or packaging options before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 56V Zener voltage is required in a hermetically sealed package. The 0.48W power rating suits low-current regulation tasks. Consider the DO-35 package constraints for PCB layout. Verify thermal management requirements against the 0.48W limit. Compare dynamic impedance specifications if precise regulation under varying current conditions is critical for the application.

Single Zener Diodes Part Context

The 1N6018B belongs to the standard 1N60xx series of Zener diodes. This series is widely used in general-purpose electronics for simple voltage clamping and regulation. The DO-35 package is a legacy but reliable form factor often found in industrial and military-grade equipment requiring hermetic sealing.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N6018 from other manufacturers offering identical 56V, 0.5W specifications in DO-35 packages. Verify pinout compatibility and hermetic sealing requirements when substituting.
