BZX55B2V7-TAP

Single Zener Diodes Overview

The BZX55B2V7-TAP is a single Zener diode from the Vishay BZX55 series, housed in a DO-35 (DO-204AH) glass axial package. It features a nominal Zener voltage of 2.7 V with a tight 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 resistance of 85 Ω and a reverse leakage current of 10 μA at 1 V. It supports junction temperatures up to 175 °C.

Single Zener Diodes Feature Summary

• Provides very sharp reverse characteristic for precise voltage regulation
• Ensures very high stability and low noise performance
• Features low reverse current level for efficient operation

Single Zener Diodes Applications

• Voltage stabilization circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-TAP' corresponds to the 10,000-unit ammopack configuration as defined in the official datasheet. Confirm that the component meets the required RoHS compliance definitions by referencing the material categorization documentation provided by Vishay. Ensure the lead length matches thermal resistance requirements for your specific application layout.

Single Zener Diodes Selection Notes

Select this component when a tight ±2% voltage tolerance is required compared to standard ±5% variants. The DO-35 through-hole package is suitable for applications requiring robust mechanical mounting. Verify that the 500 mW power dissipation rating aligns with the ambient temperature conditions and available heat sinking in the target design.

Single Zener Diodes Part Context

This part belongs to the BZX55 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series covers a wide voltage range from 2.4 V to 75 V. The 'B' designation indicates the tighter 2% tolerance band, distinguishing it from the standard 'C' tolerance devices within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZX55B2V7 variants from Vishay or equivalent 2.7 V Zener diodes in the DO-35 package from other manufacturers, provided they meet the 500 mW power and ±2% tolerance specifications.
