1N5534C/TR

Overview

The 1N5534C/TR is a single silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 14 V with a tight tolerance of ±2%. The device operates in the DO-35 axial through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 10 nA and a Zener impedance of 100 Ohms at a test current of 1 mA. It supports a wide operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides stable voltage regulation with low reverse leakage current characteristics
• Capable of operation across an extended industrial temperature range
• Utilizes hermetically sealed glass axial construction for reliability

Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify component authenticity against official Microchip Technology documentation prior to integration. Confirm that the specific suffix corresponds to the required reel packaging format. Ensure compliance with relevant environmental standards such as RoHS or REACH status applicable to the manufacturing site. Validate supply chain sources to guarantee traceability and quality assurance for critical deployments.

Selection Notes

Select this component when a 14 V regulation point with high precision is required. The ±2% tolerance makes it suitable for sensitive analog references. Consider the DO-35 package constraints for board layout. Evaluate thermal management requirements given the 500 mW dissipation limit and the specific impedance characteristics at the designated test current.

Part Context

This part belongs to the standard 1N553x series of Zener diodes produced by Microchip Technology. The 'C' designation indicates the specific voltage and tolerance class within the family. The '/TR' suffix denotes tape and reel packaging, distinguishing it from bulk packaged variants like the 1N5534C. It shares functional similarities with other axial Zener diodes but offers specific performance metrics defined by the manufacturer.
