1N4575AE3

Single Zener Diodes Overview

The Microchip Technology 1N4575AE3 is a silicon voltage reference diode belonging to the JEDEC registered 1N4565 through 1N4584A-1 series. It provides a nominal Zener voltage of 6.4 V with a tolerance of +/- 5%. The device features a temperature coefficient of 0.01%/°C (0.64 mV/°C) and operates at a test current of 2.0 mA. It is housed in a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package, suitable for operating temperatures ranging from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range
• Features internal metallurgical bonding within a hermetically sealed glass case
• Offers flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding low temperature coefficient performance
• Military applications qualifying under MIL-PRF-19500/452 standards

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'E3' confirms lead-free compliance as per manufacturer specifications. Confirm the package type matches the required DO-7 form factor. Ensure the specific temperature coefficient aligns with circuit requirements, as this series offers multiple options. Check for military prefixes if radiation hardening or specific qualification levels are needed.

Single Zener Diodes Selection Notes

Select this component when a precise 6.4 V reference with a 0.01%/°C stability is required. Consider tighter tolerance suffixes if standard 5% voltage accuracy is insufficient. Evaluate the 2.0 mA test current against available biasing resources. Compare against other series members like 1N4574A or 1N4576A if different temperature coefficients or test currents better suit the design constraints.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi (now Microchip Technology). The series provides various temperature coefficients ranging from 0.01%/°C down to 0.0005%/°C. These devices are designed for high stability and are available in multiple packages including DO-7, DO-35, and surface mount equivalents.

Single Zener Diodes Replacement Considerations

Direct substitutes include other parts within the 1N4565-1N4584A-1 series sharing the same 6.4 V nominal voltage and 0.01%/°C coefficient. Military qualified versions such as JANTX1N4575A-1 offer equivalent electrical characteristics with enhanced reliability qualifications.
