1N4579A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4579A-1/TR is a temperature-compensated Zener reference diode housed in a DO-35 (DO-204AH) through-hole package. It features a nominal Zener voltage of 6.4 V with a tight tolerance of ±0.05% and a low voltage temperature coefficient of 0.03 mV/°C. The device operates at a test current of 2 mA, dissipates up to 500 mW, and exhibits a maximum reverse leakage current of 2 µA. Designed for precision applications, it offers stable voltage regulation across an operating temperature range of -55°C to +100°C.

Single Zener Diodes Feature Summary

• Temperature compensated design ensures minimal voltage drift over varying thermal conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and temperature coefficient specifications. Ensure the DO-35 package dimensions match the target PCB footprint. Confirm lead-free compliance status if required by assembly standards. Cross-reference manufacturer part numbers to avoid confusion with non-compensated variants or different tolerance grades within the same series.

Single Zener Diodes Selection Notes

Select this component when high stability and low temperature drift are critical requirements. The 6.4 V nominal voltage is suitable for bandgap-like reference applications. Consider the 2 mA test current for power budget calculations. Verify that the ±0.05% tolerance meets the system accuracy needs compared to standard 5% Zener diodes.
