BZT03D33-TR

Single Zener Diodes Overview

The BZT03D33-TR is a unidirectional TVS diode from Vishay, packaged in SOD-57 through-hole. It features a reverse standoff voltage of 25.8V and a breakdown voltage minimum of 29.7V. The device clamps at 47.5V with a maximum peak pulse power dissipation of 1.3W. It operates within a junction temperature range up to 175°C and complies with RoHS3 standards.

Single Zener Diodes Feature Summary

• Unidirectional transient voltage suppression capability
• High thermal stability with 175°C junction temperature rating
• Robust 1.3W peak pulse power handling

Single Zener Diodes Applications

• Protection of sensitive electronic circuits against ESD events
• Guarding I/O lines in data transmission interfaces
• Surge protection for low-voltage signal lines

Single Zener Diodes Procurement Notes

Verify the specific datasheet version for the BZT03D33-TR, as it is classified as a TVS diode rather than a standard Zener. Confirm that the SOD-57 through-hole package aligns with your PCB footprint requirements. Ensure the 25.8V standoff voltage meets your circuit's operational limits before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when unidirectional protection is required for signals below 30V. The SOD-57 package suits applications needing through-hole mounting with compact dimensions. Compare the 1.3W power rating against expected surge energy levels to ensure adequate safety margins for the target environment.

Single Zener Diodes Part Context

This part belongs to the BZT03 series of surface-mount and through-hole devices. While sharing the SOD-57 form factor with other Vishay components, the D33 variant is specifically engineered for transient suppression rather than voltage regulation. It complements the broader portfolio of automotive-grade and industrial protection devices offered by the manufacturer.

Single Zener Diodes Replacement Considerations

Check for direct substitutes like BZT03D33-TAP or BZT03D33-DKRIN if available. Verify equivalent electrical parameters such as 25.8V V_RWM and 1.3W P_PPM before substitution.
