Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm RoHS compliance status, as commercial grade versions may differ from industrial specifications. Ensure the procurement documentation explicitly references the Microchip Technology part number 1N4560B to avoid confusion with legacy equivalents or generic substitutes. Confirm that the received components match the TO-204AD package dimensions and pinout configuration required by the design.

Single Zener Diodes Selection Notes

Select this component when a 5.1V Zener reference with 50W power rating is required in a TO-3 package. Consider the ±5% voltage tolerance and 0.12 Ohm dynamic impedance for precision requirements. Verify thermal management capabilities are sufficient for continuous 50W dissipation. Ensure the application environment aligns with the specified operating temperature range for reliable long-term performance.

Single Zener Diodes Part Context

The 1N4560B belongs to the JEDEC registered 1N4557B through 1N4564B series of high-power Zener diodes manufactured by Microchip Technology. This series shares common structural characteristics and regulatory compliance standards. The component is distinct within the family due to its specific 5.1V breakdown voltage, differentiating it from adjacent models like the 1N4559B or 1N4561B which offer different voltage ratings.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N4560B equivalents meeting the same 5.1V, 50W, and TO-3 specifications. Cross-reference with the broader 1N2804B through 1N2846B series if voltage compatibility allows. Verify pinout and thermal resistance parameters match before substitution.
