BZX55F20-TAP

Single Zener Diodes Overview

The BZX55F20-TAP is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 20 V with a tight tolerance of ±1%. The device is rated for a maximum power dissipation of 500 mW and utilizes the DO-204AH (DO-35) axial through-hole package. It is designed for applications requiring high stability and low noise, operating within a temperature range of -65°C 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
• Absolute reference voltage sources
• Precision analog signal conditioning

Single Zener Diodes Procurement Notes

Verify that the specific suffix 'TAP' corresponds to the Ammopack tape packaging option rather than standard reel or cut tape formats. Confirm the component meets AEC-Q101 automotive qualification requirements if intended for such environments. Ensure the ±1% tolerance variant is selected, as other tolerances exist within the BZX55 series.

Single Zener Diodes Selection Notes

Select this component when tight voltage tolerance and low noise are critical compared to standard Zener diodes. The DO-35 glass case provides robust mechanical protection. Consider the thermal management capabilities required for continuous 500 mW dissipation in the target circuit layout.

Single Zener Diodes Part Context

This part belongs to the BZX55 series of silicon planar Zener diodes. The series is characterized by its glass passivated junction and axial leaded construction. Vishay produces this line for general-purpose and precision applications requiring reliable voltage regulation in compact through-hole designs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other Vishay BZX55 variants with matching 20 V Zener voltage and ±1% tolerance, such as BZX55C20 or BZX55B20, provided the packaging format aligns with assembly requirements.
