BZV55C3V3 L1G

Single Zener Diodes Overview

The BZV55C3V3 L1G is a silicon unidirectional voltage regulator diode manufactured by Taiwan Semiconductor. It features a nominal Zener voltage of 3.3 V with a ±5% tolerance, designated by the 'C' suffix. The device operates in the Mini-MELF (LL-34-2) glass package, equivalent to JEDEC DO-213AC. It supports a maximum power dissipation of 500 mW and maintains a junction temperature range from -65 °C to +175 °C. The component is hermetically sealed, ensuring high reliability and parameter stability against junction contamination.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer lot and date code upon receipt to ensure compliance with project requirements. Confirm that the received components match the LL-34-2 package dimensions and cathode band identification. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain device integrity before soldering.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference with tight tolerance is required in a compact surface-mount form factor. The Mini-MELF package offers a smaller footprint compared to traditional axial leads while maintaining robust thermal performance. Consider the hermetic seal for environments requiring superior resistance to humidity and chemical exposure.

Single Zener Diodes Part Context

This part belongs to the BZV55 series of small signal Zener diodes produced by Taiwan Semiconductor. The series provides a comprehensive range of voltages and tolerances within the Mini-MELF package. It is designed to replace older through-hole equivalents in modern SMD assembly processes, offering improved mechanical stability and automated placement compatibility.

Single Zener Diodes Replacement Considerations

Compatible substitutes include BZV55C3V3 without the L1G suffix or other manufacturers' equivalents in the LL-34 package. Verify that replacement parts maintain the same 5% tolerance and hermetic sealing characteristics to ensure identical electrical performance and reliability standards.
