1N5229B_S00Z

Single Zener Diodes Overview

The onsemi 1N5229B_S00Z is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.3 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and a maximum Zener impedance of 22 Ohms at the test current. It is housed in a DO-35 axial through-hole package, suitable for general-purpose circuit protection and reference voltage generation.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 4.3 V level
• Capable of handling up to 500 mW of power dissipation
• Constructed with low impedance characteristics for effective noise filtering
• Utilizes a standard axial leaded package for easy PCB integration

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix S00Z against the manufacturer's latest datasheet to confirm RoHS compliance and packaging details. Ensure the DO-35 package dimensions match your board layout requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components, as generic listings may not reflect the exact onsemi manufacturing specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 4.3 V reference is required in a through-hole design. Consider the 500 mW power rating to ensure adequate thermal headroom in your application. The ±5% tolerance suits most general-purpose regulation tasks where high precision is not critical. Verify that the axial form factor fits within the mechanical constraints of the enclosure.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of small signal Zener diodes. These diodes are widely used in consumer electronics and industrial equipment for basic voltage stabilization. The 1N5229B variant specifically targets the 4.3 V market segment, offering a balance between cost and performance for non-critical regulation needs.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N5229B parts with identical electrical specifications. Ensure substitute components maintain the same DO-35 package and 500 mW power rating. Verify that any alternative offers comparable Zener impedance and leakage current characteristics to maintain circuit stability.
