1N4578A-1

Single Zener Diodes Overview

The Microchip Technology 1N4578A-1 is a temperature-compensated Zener reference diode featuring a nominal voltage of 6.4 V and a tight tolerance of ±1%. Housed in a DO-204AH (DO-35) glass axial-leaded package, it dissipates up to 500 mW with a maximum reverse leakage current of 2 µA at 3 V. The device exhibits a low impedance of 50 Ohms and operates reliably across an extended temperature range from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required military qualifications or lead-free standards. Confirm that the internal metallurgical bond option aligns with project reliability requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when high stability and low temperature drift are critical for circuit performance. Ensure the through-hole DO-35 package fits the board layout constraints and verify that the 500 mW power dissipation rating meets the thermal management needs of the application environment.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices provide a selection of 6.4 V nominal voltages with extremely low temperature coefficients, making them suitable for applications requiring precise voltage references under varying thermal conditions.

Single Zener Diodes Replacement Considerations

Consult official documentation for qualified substitutes such as JAN, JANTX, or JANTXV prefixed variants which share similar electrical characteristics but may offer different qualification levels.
