BZY55B7V5

Single Zener Diodes Overview

The BZY55B7V5 is a surface-mount Zener diode from the Taiwan Semiconductor BZY55B series, housed in an 0805 (Ceramics) package. It provides a nominal Zener voltage of 7.5 V with a tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 500 mW. Key electrical parameters include a maximum dynamic impedance of 7 Ω at the test current and a leakage current of 0.1 µA at a reverse voltage of 5.0 V. The junction temperature range spans from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Utilizes a ceramic 0805 case design for surface mounting applications.
• Offers precise voltage regulation with a standard ±2% tolerance on nominal Zener voltage.
• Complies with J-STD-020 moisture sensitivity level 1 requirements.
• Constructed to meet UL 94HB flammability ratings for the molding compound.

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix RBG when sourcing components to ensure correct packaging configuration. Confirm that the requested part matches the 0805 ceramic package variant rather than other mechanical options within the broader family. Cross-reference datasheet version D2301 to validate current specifications against legacy documentation.

Single Zener Diodes Selection Notes

Select this component for designs requiring a compact surface-mount solution with tight voltage accuracy. The 0805 ceramic package supports high-temperature soldering processes. Ensure the application current remains within the 5 mA test condition limits to maintain the specified ±2% tolerance and impedance characteristics.

Single Zener Diodes Part Context

This device belongs to the BZY55B2V4 through BZY55B36 series, which covers a wide Zener voltage range from 2.4 V to 36 V. All members of this series share the same 0805 ceramic package and 500 mW power dissipation rating. The 'B' designation indicates the tighter ±2% voltage tolerance compared to standard tolerance variants.

Single Zener Diodes Replacement Considerations

Substitutes must match the 0805 ceramic package and 7.5 V nominal voltage. Verify that alternative parts support the required 500 mW power dissipation and ±2% tolerance. Check compatibility with the specified operating temperature range of -55 °C to +150 °C.
