BZX85B8V2-TAP

Single Zener Diodes Overview

The BZX85B8V2-TAP is a silicon planar power Zener diode from the Vishay BZX85 series, designed for voltage stabilization and clipping applications. It features an 8.2 V nominal Zener voltage with a ±2% tolerance range of 8.04 V to 8.36 V. The device operates in a DO-41 axial through-hole package with a maximum power dissipation of 1.3 W at 25 °C ambient temperature. Key electrical characteristics include a dynamic resistance (rZT) of less than 5 Ω at a test current of 6.2 mA, a reverse leakage current below 1 µA at 1 V, and a temperature coefficient of +0.03%/°C to +0.07%/°C. It supports a junction temperature up to 175 °C.

Single Zener Diodes Feature Summary

• High-power silicon planar construction suitable for demanding stabilizing and clipping circuits
• Precision grading according to international E24 standards with tight ±2% voltage tolerance
• Robust thermal performance with low thermal resistance for efficient heat dissipation

Single Zener Diodes Applications

• Voltage stabilization in electronic circuits
• Signal clipping and waveform shaping
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix TAP indicates ammo pack packaging rather than tape and reel when confirming order details. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the DO-41 lead spacing matches your PCB footprint specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this part when precise voltage regulation within a narrow 2% tolerance band is required. The 1.3 W power rating allows for higher current handling compared to lower-power variants. Consider the positive temperature coefficient for applications where voltage stability across varying thermal conditions is critical.

Single Zener Diodes Part Context

This component belongs to the Vishay BZX85 series of single Zener diodes. The series offers a wide range of voltage options graded to E24 standards. The 'B' suffix denotes the tighter ±2% tolerance variant, distinguishing it from the standard ±5% 'C' grade devices within the same family.

Single Zener Diodes Replacement Considerations

Substitute with other BZX85B8V2 variants from Vishay or equivalent manufacturers offering identical 8.2 V, ±2% tolerance, and 1.3 W specifications in a DO-41 package. Verify that any replacement maintains the same thermal resistance and maximum junction temperature ratings.
