BZX85B15-TR

Single Zener Diodes Overview

The BZX85B15-TR is a silicon planar power Zener diode from the Vishay BZX85 series, housed in a DO-41 axial through-hole package. It provides a nominal Zener voltage of 15 V with a tight ±2% tolerance. The device supports a maximum power dissipation of 1.3 W and operates within a junction temperature range up to 175 °C. Key electrical characteristics include a dynamic resistance of less than 15 Ω at a test current of 11 mA, a reverse leakage current below 0.5 µA at 11 V, and an admissible continuous Zener current of 71 mA.

Single Zener Diodes Feature Summary

• High-power rating suitable for stabilizing and clipping circuits
• Tight voltage tolerance defined by the 'B' suffix designation
• Robust thermal performance with high junction temperature capability

Single Zener Diodes Applications

• Voltage stabilization
• Clipping circuits

Single Zener Diodes Procurement Notes

Verify the specific part number against official Vishay documentation to confirm the 'B' suffix indicates the required ±2% tolerance grade. Ensure the procurement channel sources genuine components matching the BZX85 series specifications. Confirm that the DO-41 package dimensions and lead configurations align with the target assembly requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required with minimal deviation. The ±2% tolerance offers superior accuracy compared to standard grades. Consider the 1.3 W power handling capability for applications requiring significant energy dissipation. Verify that the operating environment remains within the specified thermal limits to maintain reliability.

Single Zener Diodes Part Context

This component belongs to the BZX85 series of silicon planar power Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes a glass case construction in the DO-41 package. The 'B' suffix specifically denotes the tighter voltage grading standard applied to these devices within the broader product family.

Single Zener Diodes Replacement Considerations

Substitutes must match the 15 V nominal voltage, ±2% tolerance, 1.3 W power rating, and DO-41 package. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit compatibility.
