1N4567E3

Single Zener Diodes Overview

The Microchip Technology 1N4567E3 is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.002%/°C (0.13 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 hermetically sealed DO-7 (DO-204AA) glass axial package, supports an operating temperature range from -65°C to +175°C, and dissipates up to 500 mW.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm compliance with RoHS standards and ensure the correct package type is selected. Confirm that the E3 suffix aligns with the required environmental specifications for your application before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 6.4 V reference with tight temperature stability is required. Ensure the circuit design accommodates the specified 0.5 mA test current to maintain optimal voltage-temperature stability and verify that the axial leaded package fits the available board space constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A series of zero-TC reference diodes manufactured by Microsemi (now Microchip Technology). These devices are designed to provide stable voltage references across wide temperature ranges, with variations distinguished primarily by their specific temperature coefficients and test currents.
