• Offers ±3% voltage tolerance for precision regulation

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., A, B, C) as it may indicate packaging or tape-and-reel variations rather than functional differences. Confirm RoHS compliance status and current product lifecycle stage, as some variants are marked obsolete. Ensure the MSD package footprint matches the design requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.1V Zener reference is required in a through-hole configuration. Consider the 500mW power rating to ensure adequate thermal headroom in the application. Verify that the ±3% tolerance meets the circuit's accuracy requirements compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This part belongs to ROHM's MTZJT series of single Zener diodes. The series offers various voltage ratings and tolerances, packaged in the compact MSD format. These diodes are commonly used in general-purpose electronics for basic voltage clamping and reference tasks.

Single Zener Diodes Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 5.1V, 500mW specifications in an MSD package. Verify pinout compatibility and thermal characteristics if substituting with different brands.
