1N5530C

Overview

The Microchip Technology 1N5530C is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tight tolerance of ±2%. The device is rated for a power dissipation of 0.5 W and operates within a temperature range of -65 °C to +175 °C. It utilizes a DO-35 glass axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 1 µA and a Zener impedance of 60 Ω at a test current of 1 mA.

Feature Summary

• Provides stable voltage regulation with high precision due to tight voltage tolerance.
• Capable of operation in extreme thermal environments up to 175 °C.
• Constructed with hermetic glass encapsulation for environmental protection.

Applications

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

Procurement Notes

Verify the specific suffix (e.g., C, B) against the datasheet to confirm tolerance and leakage specifications. Ensure the procurement channel provides original manufacturer documentation. Confirm RoHS compliance status if required by project regulations, as military variants may differ. Validate the package type matches the PCB footprint requirements before ordering.

Selection Notes

Select this component when a 10 V reference with ±2% accuracy is required in a low-power environment. Consider the 0.5 W power rating to ensure adequate heat dissipation. The DO-35 package limits current handling compared to larger packages. Evaluate the 60 Ω impedance for dynamic load regulation needs. Verify operating temperature ranges match the system's thermal profile.

Part Context

This part belongs to the standard 1N55xx series of Zener diodes manufactured by Microchip Technology. It is functionally equivalent to other industry-standard 1N5530 devices but adheres to Microchip's specific manufacturing quality controls. The 'C' suffix typically denotes the ±2% tolerance grade. It is distinct from higher power variants like the 1N59xx series.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5530B or 1N5530C equivalents meeting the same 10 V, 0.5 W, and ±2% specifications. Cross-reference pinout and package dimensions (DO-35) to ensure mechanical compatibility. Verify that alternative parts meet the same temperature and leakage current requirements.
