BZV55B6V8

Single Zener Diodes Overview

The BZV55B6V8 is a surface-mount Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 6.8 V with a tight tolerance of ±2%. The device operates within a power dissipation rating of 500 mW and utilizes the MMELF package (DO-213AA). Electrical characteristics include a test current of 5 mA, a maximum regular impedance of 8 Ω at this current, and a leakage current of 0.1 µA when tested at 3.0 V reverse bias. The junction temperature range extends from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• High precision voltage regulation with ±2% tolerance
• Compact MMELF surface mount design for high-density layouts

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage reference circuits
• On-board DC/DC converters

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required ±2% tolerance series, as standard variants may differ. Confirm RoHS compliance status if restricted substances are mandated. Ensure the MMELF footprint aligns with the suggested pad layout dimensions provided in the datasheet. Validate thermal management requirements against the specified junction-to-ambient resistance.

Single Zener Diodes Selection Notes

Select this component when precise voltage referencing is critical due to its narrow manufacturing tolerance. The MMELF package offers a compact solution suitable for space-constrained printed circuit boards. Consider the 500 mW power dissipation limit when designing for elevated ambient temperatures or continuous operation near the upper thermal boundary.

Single Zener Diodes Part Context

This device belongs to the BZV55 series of silicon planar power Zener diodes produced by Taiwan Semiconductor. The series provides a comprehensive range of breakdown voltages from 2.4 V to 75 V. The 'B' suffix specifically denotes the tighter ±2% voltage tolerance grade compared to standard commercial grades.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering MMELF packaged Zener diodes with 6.8 V nominal voltage and ±2% tolerance. Verify compatibility of the DO-213AA mechanical outline and electrical parameters such as dynamic impedance and leakage current before substitution.
