1N4682

Single Zener Diodes Overview

The Motorola 1N4682 is a silicon unidirectional voltage regulator diode designed for hermetically sealed applications. It operates within the 1N4678 series, featuring a DO-204AH (DO-35) glass package with double slug construction. The device provides a nominal Zener voltage of 2.7V and supports a maximum power dissipation of 0.5W. It utilizes metallurgically bonded construction to ensure reliability in harsh environments.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction using double slug type design
• Metallurgically bonded internal structure for enhanced durability
• Compact DO-204AH package form factor smaller than conventional DO-204AA

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• Reference voltage generation in high-reliability circuits
• Overvoltage protection in aerospace instrumentation

Single Zener Diodes Procurement Notes

Verify that the specific procurement lot matches the original Motorola specifications for the 1N4678 series. Confirm the presence of the hermetic seal and correct JEDEC-95 code DO-204AH. Ensure the component meets the required metallurgical bonding standards for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, low-voltage Zener reference is required for critical systems. The 2.7V rating suits specific logic level references. Consider the DO-204AH package constraints for board space and thermal management requirements in enclosed assemblies.

Single Zener Diodes Part Context

This part belongs to the 1N4678 series of 500mW glass Zener diodes. It shares mechanical characteristics with other members of this family, including corrosion-resistant external finishes and standardized axial lead configurations suitable for through-hole mounting in ruggedized equipment.

Single Zener Diodes Replacement Considerations

Substitute parts must maintain the 2.7V Zener voltage, 0.5W power rating, and hermetic sealing capability. Verify compatibility with the DO-204AH footprint and ensure the replacement meets the same metallurgical bonding and temperature resistance standards.
