1N4696

Overview

The Microchip Technology 1N4696 is a 500 mW axial-leaded Zener diode housed in a hermetically sealed DO-7 (DO-204AA) glass package. It provides a nominal Zener voltage of 9.1 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and features an internal metallurgical bond for enhanced reliability. Key electrical parameters include a maximum reverse leakage current of 1 µA at the rated voltage, a test current of 50 µA, and a maximum DC Zener current of 52.4 mA.

Feature Summary

• Hermetically sealed glass axial-lead construction with internal metallurgical bonding
• Voltage regulation capability across a broad operating current and temperature range
• Radiation hard design inherent to the component structure
• ESD insensitivity compliant with MIL-STD-750 Method 1020

Applications

• Voltage regulation over wide operating current and temperature ranges
• Reference voltage generation in precision circuits
• Protection against voltage transients in sensitive electronics

Procurement Notes

Verify the specific manufacturer source, as historical production involves Microsemi and Microchip Technology. Confirm compliance requirements such as RoHS status and screening options like JAN or JANS prefixes if military-grade specifications are required. Ensure the ordering suffix matches the desired tolerance level, as standard parts lack additional suffixes while tighter tolerances require specific letters.

Selection Notes

Select this component for applications requiring high-reliability voltage regulation in harsh environments due to its wide temperature rating and radiation hardness. The DO-7 package offers flexible axial-lead mounting suitable for through-hole PCB designs. Consider the thermal resistance characteristics when designing heat dissipation strategies, noting the derating curve for steady-state power above 25°C ambient temperature.

Part Context

The 1N4696 belongs to the 1N4678 through 1N4717 series of 0.5-watt Zener voltage regulators. This family provides a selection of voltages from 1.8 to 43 volts with standard 5% tolerances. The series is JEDEC registered and includes options for tighter tolerances via suffix letters. Equivalent DO-35 glass body versions and surface mount DO-213AA variants are also available within this product line.

Replacement Considerations

Equivalent DO-35 glass body axial-leaded Zeners are available within the same series. Surface mount equivalents in the DO-213AA package outline can be identified by adding UR or UR-1 suffixes to the part number.
