1N5519/TR

Overview

The Microchip Technology 1N5519/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.6 V with a 5% tolerance and operates at a test current of 20 mA. The device has a maximum power dissipation of 500 mW and a Zener impedance of 24 Ohms. It utilizes a DO-35 (DO-204AH) axial through-hole package and is supplied in tape-and-reel packaging. The component supports a wide operating temperature range from -65°C to +175°C junction temperature, with a maximum reverse leakage current of 3 µA.

Feature Summary

• Provides stable voltage regulation at a nominal 3.6 V level
• Capable of handling up to 500 mW of power dissipation
• Engineered for reliable operation across extended industrial temperature ranges

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Biasing networks within analog signal processing equipment

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm the exact manufacturing lot and testing standards associated with the /TR variant. Ensure that the required tape-and-reel quantity multiples align with your production volume requirements before finalizing procurement orders. Cross-reference the datasheet revision history to validate compliance with current environmental regulations and material declarations.

Selection Notes

Select this component when a 3.6 V regulation point is required within a through-hole design constraint. The 500 mW power rating allows for moderate current handling capabilities suitable for general-purpose regulation tasks. Consider the 24 Ohm impedance value when designing for load regulation performance in sensitive analog applications.

Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It shares the same electrical characteristics as other variants in the series but differs in its specific packaging configuration. The /TR suffix indicates a reel-based supply format intended for automated assembly processes.

Replacement Considerations

Consult official substitution guides for equivalent parts such as JAN1N5519B-1 or 1N5519D if different tolerance or packaging specifications are required.
