1N4568A-1

Single Zener Diodes Overview

The Microchip Technology 1N4568A-1 is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a tight tolerance of ±0.1%. It operates at a test current of 500 µA, dissipating up to 500 mW in a DO-35-2 through-hole package. The device features an extremely low voltage temperature coefficient of 0.001 %/°C and a maximum reverse leakage current of 2 µA. It supports an operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage drift over wide thermal ranges
• High precision voltage regulation with ±0.1% tolerance
• Internal metallurgical bond construction for enhanced reliability

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature compensated oscillator stabilization
• High-stability power supply regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration when ordering, as the -1 suffix denotes internal metallurgical bonding which affects qualification status. Confirm that the required voltage tolerance matches the standard ±0.1% specification rather than the broader ±5% available in non-A variants. Ensure the procurement channel provides traceable documentation suitable for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when superior thermal stability is required compared to standard Zener diodes. The 6.4 V nominal voltage is optimal for applications needing a stable reference near the silicon bandgap energy. Consider the DO-35 package constraints for board space and verify that the 500 µA test current aligns with the system's biasing capabilities to maintain specified accuracy.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-Temperature Coefficient (Zero-TC) reference diodes manufactured by Microchip Technology. These devices are engineered to provide stable reference voltages by balancing the positive temperature coefficient of the Zener effect with the negative coefficient of the avalanche effect.
