• Military qualified per MIL-PRF-19500/406 standards suitable for high-reliability applications.
• Inherently radiation hard and non-sensitive to electrostatic discharge.
• Triple-layer passivation provides enhanced protection against environmental factors.

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• High-reliability aerospace circuits where failure is not tolerated
• Radiation-hardened signal conditioning modules

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the package type corresponds to the D-5A MELF form factor. Ensure the procurement documentation references the correct military qualification standard. Check for any specific handling requirements related to the hermetic seal integrity during assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 10V reference with tight 2% tolerance is required in a surface mount configuration. Consider the 1.5W power rating and thermal resistance values for heat dissipation planning. Evaluate the operating temperature range against the application's environmental extremes. Compare the dynamic impedance specifications against circuit sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt glass Zener diodes. These devices are designed as surface mount equivalents to popular JEDEC registered axial lead series. The series offers a wide selection of voltages from 3.3 to 200 Volts with various tolerance options available across different reliability levels.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 10V nominal voltage, 1.5W power rating, and D-5A MELF package dimensions. Verify equivalent military qualification if the application requires MIL-PRF-19500/406 compliance. Ensure the replacement device maintains the same 2% tolerance specification and thermal characteristics.
