LLZ5233B

Single Zener Diodes Overview

The LLZ5233B is a hermetically sealed glass Zener diode manufactured by Taiwan Semiconductor. It features a Mini-MELF (MMELF-2) surface-mount package and provides a nominal Zener voltage of 6V with a tolerance of 5%. The device is rated for a power dissipation of 500mW and operates within a temperature range extending up to 200°C. Constructed with compression-bonded glass, it offers corrosion resistance and solderable leads.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction ensures long-term reliability and environmental protection.
• Mini-MELF surface-mount package facilitates automated assembly and compact circuit design.
• Compression-bonded internal structure provides robust mechanical stability.

Single Zener Diodes Applications

• Voltage regulation in surface-mount electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in precision applications

Single Zener Diodes Procurement Notes

Verify the specific suffix or variant code against the manufacturer's current datasheet to ensure compatibility with required tolerance and packaging specifications. Confirm that the Mini-MELF footprint matches the target PCB layout. Check for RoHS compliance status if restricted substances are a constraint for the final assembly process.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, high-reliability Zener diode is required in a small surface-mount form factor. The 500mW power rating and 6V nominal voltage define its operational limits. Ensure the application environment does not exceed the maximum operating temperature specified for the glass package construction.

Single Zener Diodes Part Context

This part belongs to the Mini-MELF series of Zener voltage regulators from Taiwan Semiconductor. These devices utilize a glass passivation technique distinct from plastic-encapsulated alternatives, offering superior stability in harsh environments. The LLZ5233B specifically denotes the 6V variant within this standardized lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' Mini-MELF Zener diodes offering identical 6V nominal voltage, 5% tolerance, and 500mW power dissipation. Verify pinout orientation and physical dimensions match the MMELF-2 package before substitution.
