• Totally lead-free and fully RoHS compliant
• Halogen and antimony free green device
• Ideally suited for automated assembly processes

Single Zener Diodes Applications

• Voltage regulation in compact electronic circuits
• Clamping applications for transient voltage suppression
• Reference voltage sources in low-power systems

Single Zener Diodes Procurement Notes

Verify the manufacturer designation as Taiwan Semiconductor Corporation against the specific part marking. Confirm the SOD-323 package type and 500 mW power rating match the design requirements. Ensure compliance with RoHS and halogen-free specifications if required by the end application standards.

Single Zener Diodes Selection Notes

Select this component when a 22 V reference or regulation point is needed in space-constrained designs. The SOD-323 package offers a small footprint compared to larger axial leads. Consider the ±10% tolerance for general-purpose applications where tighter precision is not critical.

Single Zener Diodes Part Context

This component belongs to the BZT52C series of surface mount Zener diodes. The series typically includes various voltage ratings within the same SOD-323 package form factor. These devices are designed for general-purpose voltage regulation and protection in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering BZT52C22 variants in SOD-323 packages. Verify that substitute parts maintain the 500 mW power dissipation and 22 V nominal voltage. Check for equivalent AEC-Q101 qualification if automotive reliability is required.
