1N4564RB

Single Zener Diodes Overview

The Microchip Technology 1N4564RB is a high-power Zener diode rated at 200 V with a maximum power dissipation of 50 W. It features a nominal voltage tolerance of ±5% and is housed in a TO-204AD (TO-3) through-hole package. The device operates within a junction temperature range of -65°C to +175°C, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad range up to 200 V
• Capable of handling high power loads up to 50 W with adequate heat sinking
• Qualified for MIL-PRF-19500/114 standards including JAN, JANTX, and JANTXV levels

Single Zener Diodes Applications

• High-voltage power supply regulation
• Industrial control systems requiring robust voltage reference
• Military and aerospace electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as availability varies by grade. Confirm that the TO-204AD package mounting requirements align with your thermal management design. Ensure compliance with relevant military specifications if operating in qualified environments.

Single Zener Diodes Selection Notes

Select this component when a 200 V Zener reference is needed with high power handling capabilities. Consider the TO-3 package size for mechanical integration. Evaluate thermal resistance requirements to ensure the 50 W rating can be sustained under actual operating conditions without exceeding junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N2804B through 1N2846B series of 50 Watt Zener diodes manufactured by Microchip Technology. These devices are JEDEC registered and designed for applications requiring reliable voltage regulation in high-power scenarios. The RB suffix typically denotes a specific qualification or packaging variant within the broader product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other parts from the 1N28xx series with matching 200 V ratings and 50 W power dissipation. Verify pinout compatibility and thermal characteristics before substitution. Alternative manufacturers may offer equivalent performance but require validation against MIL-PRF-19500/114 standards.
