1N4568-1

Single Zener Diodes Overview

The Microchip Technology 1N4568-1 is a temperature-compensated Zener reference diode featuring a nominal voltage of 6.4 V with a tolerance of +/- 5%. It operates at a test current of 0.5 mA and dissipates up to 500 mW. The device utilizes a glass axial-leaded DO-35 package with an internal metallurgical bond, indicated by the -1 suffix. It supports a wide operating temperature range from -65°C to +175°C and exhibits a low voltage temperature coefficient for minimal drift.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable reference voltage
• Internal metallurgical bond construction for reliability
• Wide operating temperature capability

Single Zener Diodes Applications

• Precision voltage reference circuits
• Military and aerospace instrumentation
• High-reliability power supply regulation

Single Zener Diodes Procurement Notes

Verify the specific military qualification level required, as the base part number may differ from JAN, JANTX, or JANS variants. Confirm the presence of the internal metallurgical bond via the -1 suffix. Ensure the DO-35 through-hole package matches the PCB layout requirements. Check for RoHS compliance status if applicable to the specific manufacturing lot.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is needed across extreme temperatures. The DO-35 package suits through-hole designs requiring robust mechanical bonding. Consider the 500 mW power dissipation limit and derating curves above 50°C. Compare against other series members like 1N4565 or 1N4584 if different voltage levels are acceptable.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microchip (formerly Microsemi). These components are designed for applications demanding high stability and are often qualified to MIL-PRF-19500/452 standards when prefixed appropriately. The series offers various nominal voltages centered around the 6.4 V band.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N4568 variants such as CDLL4568A for surface mount needs, though package differences apply. Verify compatibility with JAN1N4568 or JANTX1N4568 if military specs are required.
