1N4565AE3

Single Zener Diodes Overview

The Microchip Technology 1N4565AE3 is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.01%/°C. It operates at a test current of 0.5 mA, features a maximum reverse current of 2.0 µA at 3 V, and has a dynamic impedance of 200 Ohms. The device is housed in a hermetically sealed DO-7 (DO-204AA) glass axial-leaded package, supports an operating temperature range from -65°C to +175°C, and dissipates up to 500 mW.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation and other circuit designs requiring a voltage reference

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the source datasheet identifies Microsemi Scottsdale Division while the prompt specifies Microchip Technology. Confirm that the 'E3' suffix denotes lead-free compliance if required by your assembly specifications. Ensure the component matches the DO-7 package dimensions and hermetic sealing requirements detailed in the official documentation.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.01%/°C temperature coefficient is required. It is suitable for applications needing low test currents of 0.5 mA. Consider tighter tolerance options or different test currents if the standard specifications do not meet design constraints.
