• Overvoltage protection in aerospace systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct tolerance and bonding type. Confirm military qualification requirements if applicable. Check RoHS status as non-compliant variants exist. Validate package dimensions against PCB footprint specifications before integration.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V reference with 2% tolerance is required in a compact surface mount form factor. Consider the 1.4 kΩ impedance for noise-sensitive applications. Ensure the operating environment stays within the specified thermal limits for long-term stability.

Single Zener Diodes Part Context

This part belongs to the 1N4614-1 through 1N4627-1 series of 0.5 W glass surface mount Zener regulators. These devices offer internal metallurgical bonding identified by the "-1" suffix, providing superior mechanical integrity compared to non-bonded types. The series covers voltages from 1.8 to 100 V.

Single Zener Diodes Replacement Considerations

JAN1N4626-1 offers equivalent electrical performance in bulk packaging. 1N4626UR/TR provides similar specifications without the military-grade metallurgical bond. Verify pinout compatibility and thermal characteristics when substituting.
