1N4569A

Single Zener Diodes Overview

The Microchip Technology 1N4569A is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.0005%/°C (0.03 mV/°C). It operates at a test current of 0.5 mA, features a maximum reverse leakage current of 2 µA at 3 V, and has a dynamic impedance of 200 Ohms. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package, dissipates 500 mW, and supports an operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet originates from Microsemi while the brand is listed as Microchip Technology. Confirm that the component meets the required JEDEC registration standards for the 1N4565 series. Ensure the ordering suffix matches the desired tolerance or military qualification if applicable, as standard part numbers may differ from specialized variants.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with ultra-low temperature drift is required. The 0.5 mA test current setting makes it suitable for low-power applications compared to higher current variants in the series. Verify that the DO-7 package dimensions fit the target PCB layout and that the operating temperature range aligns with the system environment.
