1N5226B_S00Z

Single Zener Diodes Overview

The onsemi 1N5226B_S00Z is a single silicon Zener voltage regulator diode designed for surface-mount applications. It features a nominal Zener voltage of 3.3 V with a tolerance of ±5%. The device operates within a maximum power dissipation of 500 mW and utilizes the SOD-123 package. Key electrical parameters include a test current of 20 mA, a maximum Zener impedance of 28 Ω, and a maximum reverse leakage current of 25 μA. The component supports an operating temperature range from -55°C to 150°C and complies with RoHS standards.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 3.3 V level
• Utilizes a compact SOD-123 surface-mount package for efficient PCB layout
• Features a glass passivated junction for enhanced reliability

Single Zener Diodes Applications

• General-purpose voltage reference circuits
• Overvoltage protection in low-power electronics
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix _S00Z against official manufacturer documentation to confirm exact tape-and-reel specifications or marking codes. Ensure that the sourcing channel provides valid traceability data consistent with onsemi quality standards. Cross-reference the part number with authorized distributor catalogs to confirm availability and compliance status prior to procurement.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference is required in space-constrained designs utilizing SMD technology. Consider the 500 mW power rating and 28 Ω impedance characteristics for circuit stability. Compare against axial-leaded equivalents if through-hole mounting is mandatory, noting the significant difference in thermal performance and physical footprint between SOD-123 and DO-35 packages.

Single Zener Diodes Part Context

This part belongs to the broader family of Zener voltage regulator diodes manufactured by onsemi. While the base model 1N5226B typically denotes an axial DO-35 package, the _S00Z suffix indicates a specific surface-mount variant, likely corresponding to the SOD-123 form factor. This distinction is critical for automated assembly processes and board design constraints.

Single Zener Diodes Replacement Considerations

Direct substitutes include MMSZ5226BT1G and MMBZ5226BLT1G from onsemi, which share identical electrical characteristics and 3.3 V regulation. Other manufacturers offer equivalent parts under the 1N5226B designation, though package variations such as DO-35 require mechanical adaptation.
