1N4560RB

Single Zener Diodes Overview

The 1N4560RB is a hermetically sealed, high-power Zener diode manufactured by Microchip Technology. It features a silicon construction with a nominal Zener voltage of 5.1V and a tight tolerance of 1%. The device is designed for robust voltage regulation applications, capable of dissipating up to 50W when mounted with adequate heat sinking. It utilizes an internal solder bond construction within a TO-3 metal package (JEDEC TO-204AD), ensuring durability in demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed welded construction for environmental protection
• Internal solder bond design for mechanical stability
• High power dissipation capability up to 50W
• Tight voltage tolerance for precise regulation

Single Zener Diodes Applications

• Voltage regulation in high-power circuits
• Military and aerospace electronic systems
• Industrial equipment requiring reliable reference voltages

Single Zener Diodes Procurement Notes

Verify the specific suffix RB against official Microchip documentation to confirm exact qualification levels and testing standards. Ensure that the procurement channel provides valid traceability for hermetically sealed components. Confirm compliance requirements such as lead content and RoHS status prior to ordering, as these specifications are critical for final assembly integration.

Single Zener Diodes Selection Notes

Select this component when a stable 5.1V reference is required in high-power scenarios. The TO-3 package necessitates appropriate thermal management solutions to handle the 50W dissipation rating. Consider the hermetic seal requirement if the operating environment involves moisture or harsh conditions where standard plastic packages would fail.

Single Zener Diodes Part Context

This part belongs to the 1N45xxB series of high-power Zener diodes from Microchip. These devices are JEDEC registered and offer a broad range of voltage values. The series is known for its reliability in critical applications, often supporting JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/114 standards.

Single Zener Diodes Replacement Considerations

Cross-reference with other 1N4560 variants or equivalent 50W Zener diodes in TO-3 packages. Verify pinout compatibility and thermal resistance characteristics before substituting.
