BZX55F8V2-TR

Single Zener Diodes Overview

The BZX55F8V2-TR is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 8.2 V with a tolerance of ±1%. The device is rated for a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. It utilizes the DO-204AH (DO-35) axial through-hole package and carries AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight ±1% tolerance for sensitive circuit applications
• Automotive-grade reliability certified under AEC-Q101 standards
• Capable of operation in extreme thermal environments ranging from -65°C to +175°C

Single Zener Diodes Applications

• Precision voltage reference circuits in automotive electronics
• Over-voltage protection stages requiring tight tolerance
• Clamping applications in high-reliability industrial systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'F' indicates the ±1% tolerance variant, distinct from standard 'C' (±5%) or 'G' (±2%) series parts. Confirm the '-TR' designation corresponds to tape-and-reel packaging requirements for automated assembly lines. Ensure the DO-204AH package dimensions match the target PCB footprint before procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required, as the F suffix denotes tighter tolerances than standard variants. The 500 mW power rating suits low-current regulation tasks. Verify that the axial DO-35 package fits the mechanical constraints, as surface-mount alternatives like BZX84 exist for space-limited designs.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX55 series of glass-passivated junction Zener diodes. The series is widely used in general-purpose regulation and protection. The BZX55F variant specifically targets applications demanding higher precision than the standard BZX55C series, offering improved stability for critical analog and digital logic interfaces.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay BZX55F8V2 variants with different packaging such as BZX55F8V2-TAP for ammo pack supply. Cross-brand equivalents require matching the 8.2 V nominal voltage, ±1% tolerance, 500 mW power rating, and DO-35 package form factor.
