• Reference voltage sources for analog circuits
• Overvoltage protection in signal lines

Single Zener Diodes Procurement Notes

Verify that the part number suffix matches the required specifications, as different suffixes indicate variations in tolerance or screening levels. Confirm RoHS compliance status if lead-free soldering is required for the assembly process. Ensure the procurement source provides official datasheets to validate electrical parameters against the JEDEC registered standards.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6 V reference is needed with tight ±5% tolerance. Consider the positive temperature coefficient for thermal stability requirements. Evaluate the power dissipation limits relative to the ambient temperature and mounting conditions to ensure operation remains within the specified derating curve.

Single Zener Diodes Part Context

This component belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V in the standard DO-35 glass axial-lead package. It serves as a fundamental discrete semiconductor solution for voltage clamping and regulation tasks.

Single Zener Diodes Replacement Considerations

Equivalent surface mount options are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. Military screening levels can be obtained by adding specific prefixes such as MQ, MX, MV, or MSP to parts with the "-1" suffix.
