1N4580-1

Single Zener Diodes Overview

The Microchip Technology 1N4580-1 is a temperature-compensated Zener reference diode housed in a DO-35 glass axial-leaded package. It provides a nominal Zener voltage of 6.4 V with a tight tolerance of +/- 1% at a test current of 4 mA. The device features an internal metallurgical bond, indicated by the -1 suffix, ensuring structural integrity for demanding environments. Key electrical parameters include a maximum reverse leakage current of 2 uA and a Zener impedance of 25 Ohms. It operates within a wide temperature range from -65 C to +175 C with a power dissipation rating of 500 mW.

• High precision voltage regulation with tight tolerance specifications

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable output
• Military and aerospace electronic systems
• High-reliability instrumentation and measurement equipment

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N4580 series originates from multiple qualified suppliers including Microsemi and Microchip. Confirm that the -1 suffix correctly denotes the internal metallurgical bond required for your application. Ensure compliance with relevant military qualification standards such as MIL-PRF-19500/452 if specified in your design requirements. Check for RoHS status variations between different manufacturing lots or sources.

Single Zener Diodes Selection Notes

Select this component when a highly stable 6.4 V reference is needed with superior thermal performance compared to standard Zener diodes. The internal metallurgical bond makes it suitable for applications subject to mechanical shock or vibration. Consider the DO-35 through-hole package constraints against available board space. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-Temperature Coefficient Reference Diodes. These devices are engineered to provide a stable reference voltage with very low drift over temperature. The series offers various nominal voltages, with the 1N4580-1 specifically targeting the 6.4 V point. The -1 suffix indicates a specialized package construction option available across JAN, JANTX, and JANTXV military qualifications.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other parts from the 1N4565-1N4584A-1 series with matching voltage and bond specifications. Military-grade equivalents such as JANTX1N4580A-1 may be used if higher qualification levels are required. Surface mount alternatives like CDLL4580A exist but require package adaptation.
