1N5519C/TR

Overview

The 1N5519C/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 3.6V and a power dissipation rating of 500mW. The device utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical specifications include a tight tolerance of ±2% and an operating junction temperature range from -65°C to +175°C. This component is classified under Diodes & Rectifiers and is intended for use in circuits requiring precise voltage reference or regulation.

Feature Summary

• Provides stable voltage regulation with a nominal Zener voltage of 3.6V
• Offers high precision with a tight tolerance of ±2%
• Supports wide thermal operation within a junction temperature range of -65°C to +175°C
• Utilizes a standard DO-204AH axial leaded package for through-hole mounting

Applications

• Voltage regulation in electronic circuits
• Voltage reference sources
• Overvoltage protection circuits

Procurement Notes

Verify the specific suffix 'C' indicates the ±2% tolerance variant when sourcing. Confirm the 'TR' designation corresponds to the manufacturer's standard tape and reel packaging requirements for your assembly line. Ensure compatibility with the DO-204AH footprint on your PCB layout. Check current supply status as availability may vary by region and distributor.

Selection Notes

Select this component when a precise 3.6V reference is required with minimal deviation. The ±2% tolerance makes it suitable for applications demanding higher accuracy than standard 5% or 10% Zener diodes. Consider the 500mW power rating to ensure adequate heat dissipation in your design. The wide temperature range supports operation in harsh environments where standard silicon devices might fail.

Part Context

This part belongs to the Microchip Technology single Zener diode family, specifically within the 1N55xx series. These components are widely used in discrete semiconductor applications for basic voltage control. The 1N5519C/TR represents a high-precision variant within this lineage, distinguished by its tighter manufacturing tolerances compared to standard commercial grade equivalents.

Replacement Considerations

Direct substitutes include other 3.6V Zener diodes with similar power ratings and package types. Verify that any replacement maintains the ±2% tolerance if precision is critical. Ensure the alternative device supports the same operating temperature range and uses the DO-204AH/DO-35 form factor for mechanical compatibility.
