BZX85C27-TAP

Single Zener Diodes Overview

The Vishay BZX85C27-TAP is a silicon planar power Zener diode in the DO-41 axial through-hole package. It provides a nominal Zener voltage of 27 V with a tolerance range of 25.1 V to 28.9 V at a test current of 20 mA. The device supports a maximum power dissipation of 1.3 W and operates within a junction temperature range of -55 °C to +175 °C. Key electrical characteristics include a dynamic resistance (rZT) of less than 30 Ω, a reverse leakage current below 0.5 µA at 24 V, and an admissible Zener current of 41 mA.

Single Zener Diodes Feature Summary

• Designed for high-power stabilization and clipping applications
• Features a glass case construction for robust mechanical integrity
• Voltage grading aligns with international E24 standard values

Single Zener Diodes Applications

• Voltage stabilization circuits
• Signal clipping circuits

Single Zener Diodes Procurement Notes

Verify that the component matches the specific BZX85C27 designation and TAP packaging code. Confirm compliance with RoHS directives and ozone-depleting substance policies as outlined by the manufacturer. Ensure the supplier documentation references the correct datasheet revision for accurate electrical parameter validation prior to integration.

Single Zener Diodes Selection Notes

Select this component when a 27 V reference point is required in through-hole designs. The 1.3 W power rating allows for higher energy handling compared to lower-power series. Verify that the circuit design accommodates the specified thermal resistance and that the operating conditions remain within the defined absolute maximum ratings for reliable performance.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX85 Series of silicon planar power Zener diodes. The series offers a wide range of voltage options graded to E24 standards. The 'C' suffix indicates a ±5% voltage tolerance, while the 'TAP' suffix denotes the ammo pack packaging option containing 5,000 units per reel.

Single Zener Diodes Replacement Considerations

Substitutes must match the 27 V nominal voltage, 1.3 W power rating, and DO-41 package. For tighter tolerances, consider the BZX85B27 variant which offers ±2% accuracy.
