Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' corresponds to the required 10% tolerance. Confirm the manufacturer origin, as the datasheet references Microsemi while the prompt specifies Microchip Technology. Ensure the component meets RoHS compliance requirements if applicable by checking for the 'e3' suffix designation on the physical part or ordering documentation.

Single Zener Diodes Selection Notes

Select this component when a 130 V Zener voltage is required in a standard DO-35 axial package. The 0.5 W power dissipation rating suits low-to-medium power regulation tasks. Consider the positive temperature coefficient for thermal stability analysis. Verify that the 1100 Ω impedance meets the circuit's dynamic load requirements.

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. These devices are JEDEC registered and utilize a hermetically sealed glass DO-35 package. The series supports various tolerance options and military screening levels via specific prefixes and suffixes.

Single Zener Diodes Replacement Considerations

Consult the official datasheet for exact parameter matching. Equivalent parts must maintain the 130 V nominal voltage, 0.5 W power rating, and DO-35 package form factor. Verify compatibility regarding Zener impedance and reverse leakage current specifications before substitution.
