1N5525C

Overview

The Microchip Technology 1N5525C is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a tight tolerance of ±1%. The device operates in the DO-204AH (DO-35) axial through-hole package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 1 µA at 5 V, a Zener impedance of 30 Ohms, and a forward voltage of 1.1 V at 200 mA. It supports a wide operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides precise voltage regulation with a narrow ±1% tolerance on the 6.2 V Zener voltage.
• Capable of operation in extreme thermal environments ranging from -65°C to +175°C.
• Utilizes an axial leaded DO-204AH package suitable for standard through-hole mounting.

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates the required ±1% tolerance level during procurement. Confirm that the DO-204AH package dimensions align with the target PCB footprint. Ensure the selected component meets the necessary thermal dissipation requirements for the intended application environment.

Selection Notes

Select this component when high voltage accuracy is critical, as indicated by the ±1% tolerance. Consider the 500 mW power rating and the 30 Ohm impedance for circuit stability. The extended temperature range makes it suitable for industrial or automotive environments where standard commercial parts may fail.

Part Context

This part belongs to the 1N5525 series of Zener diodes manufactured by Microchip Technology. While other variants like 1N5525B offer ±5% tolerance, the 1N5525C provides tighter precision. It shares the same physical package and general power handling characteristics as its series counterparts but differs in voltage accuracy specifications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 1N5525C equivalents if sourcing from alternative manufacturers, ensuring matching voltage, tolerance, and package constraints.
