1N5266/TR

Single Zener Diodes Overview

The Microchip Technology 1N5266/TR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 68 V with a tolerance of ±5%. The device operates in a DO-35-2 through-hole package and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 230 Ohms, and a test current of 1.8 mA. It supports an operating temperature range from -65°C to +175°C and exhibits a voltage temperature coefficient of 0.097 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 68 V level with tight manufacturing tolerances.

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm packaging format and screening levels. Ensure that the required tolerance and thermal specifications align with the design constraints before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when a precise 68 V regulation point is required with strict tolerance limits. Consider the DO-35 package dimensions for board layout compatibility. Evaluate the thermal management requirements given the 500 mW dissipation limit and the specified operating temperature range for the intended application environment.

Single Zener Diodes Part Context

This component belongs to the broader family of 1N52xx series Zener diodes manufactured by Microchip Technology.
