1N4692-1

Overview

The Microchip Technology 1N4692-1 is a 0.5 W axial-leaded Zener voltage regulator housed in a hermetically sealed glass DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 6.8 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65 °C to +175 °C. Key electrical characteristics include a test current of 50 µA, a maximum reverse leakage current of 10.0 µA at the rated voltage, and a maximum DC Zener current of 70 mA.

Feature Summary

• Hermetically sealed internal metallurgical bond construction
• Voltage regulation capability across a broad operating current and temperature range
• Inherent radiation hardness suitable for demanding environments
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020

Applications

• Precision voltage reference circuits
• Overvoltage protection networks
• Temperature-compensated Zener diodes
• Shunt voltage regulators

Procurement Notes

Verify the specific reliability level required, as commercial versions lack military screening prefixes. Confirm RoHS compliance status, noting that compliant plating is available on commercial grade devices only. Ensure the ordering suffix matches the desired tolerance and packaging configuration. Cross-reference the part number against the manufacturer's latest datasheet to confirm availability of up-screening options.

Selection Notes

Select this component when a stable 6.8 V reference is needed in an axial leaded form factor. Consider the tight thermal resistance values for heat dissipation calculations in enclosed spaces. Evaluate the low capacitance characteristics if high-frequency noise filtering is required alongside voltage regulation. Verify that the 500 mW power rating aligns with the circuit's peak dissipation requirements.

Part Context

This device belongs to the 1N4678-1 through 1N4717-1 series of 0.5 W Zener diodes. The series covers a voltage selection from 1.8 V to 43 V. All parts in this family share the same DO-35 glass package and metallurgical bond technology. The series offers optional tighter tolerances and various reliability screening levels.

Replacement Considerations

Equivalent parts include the 1N4692 without the -1 suffix for non-bonded versions, or surface mount equivalents like the 1N4692UR-1.
