1N5527C/TR

Overview

The Microchip Technology 1N5527C/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates in the DO-204AH (DO-35) axial through-hole package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 500 nA, a Zener impedance of 35 Ohms at a test current of 1 mA, and a forward voltage of 1.1 V at 200 mA. It supports an extended junction temperature range from -65°C to +175°C.

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference circuits
• Capable of operation across an extended industrial temperature range up to 175°C
• Utilizes a standard axial through-hole package for reliable PCB mounting

Applications

• Precision voltage reference sources
• Overvoltage protection circuits
• Voltage clamping applications

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards if mandated by your project specifications. Ensure the selected distributor is authorized to handle Microchip Technology products to guarantee authenticity and traceability of the semiconductor devices.

Selection Notes

Select this component when a high-precision 7.5 V reference is required with minimal voltage deviation. The ±2% tolerance distinguishes it from lower-accuracy variants like the 'A' or 'B' suffixes. Consider the thermal management capabilities provided by the 500 mW power dissipation rating and the robustness of the axial leaded construction for through-hole implementations.

Part Context

This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options and tolerance grades, typically packaged in the DO-204AH form factor. The 'C' suffix specifically denotes the tighter ±2% voltage tolerance compared to other series members, while the '/TR' suffix identifies the reel packaging configuration.

Replacement Considerations

Direct parameter-equivalent substitutes within the same manufacturer family include the 1N5527C (bulk packaging) and the 1N5527D/TR (±5% tolerance). Cross-manufacturer replacements must match the 7.5 V Zener voltage, 500 mW power rating, and DO-204AH package dimensions to ensure mechanical and electrical compatibility.
