1N5266B-TAP

Single Zener Diodes Overview

The Vishay 1N5266B-TAP is a silicon planar power Zener diode with a nominal voltage of 68 V and a maximum power dissipation of 500 mW. It features a standard ±5% tolerance indicated by the 'B' suffix, housed in a DO-35 (DO-204AH) axial glass package. The device operates within a junction temperature range of -65 °C to +175 °C and includes a cathode identification band for polarity orientation.

Single Zener Diodes Feature Summary

• Silicon planar construction for reliable voltage regulation
• Standardized ±5% Zener voltage tolerance
• High thermal stability up to 175 °C junction temperature

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the required tolerance level, as the 'B' suffix specifically denotes ±5%. Confirm the TAP suffix corresponds to the ammopack tape format. Ensure the application environment remains within the specified thermal limits to maintain performance integrity.

Single Zener Diodes Selection Notes

Select this component when a precise 68 V reference is needed in a through-hole design. The DO-35 package provides robust mechanical support for axial mounting. Consider the specific test current requirements during circuit design to ensure accurate voltage regulation under load.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series, which covers a wide Zener voltage range from 2.4 V to 75 V. All devices share the same 500 mW power rating and DO-35 package style, differing primarily in their breakdown voltage and associated test currents.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5266 equivalents. Verify that any substitute maintains the 68 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure physical and electrical compatibility.
