1N5533C

Overview

The Microchip Technology 1N5533C is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of ±5%. The device operates at a test current of 1 mA 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 90 Ohms. It supports an operating temperature range from -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation using avalanche breakdown principles.
• Features low reverse leakage current for high-impedance circuit stability.
• Capable of operation in extreme temperature environments up to 175°C.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications for transient voltage suppression.

Procurement Notes

Verify the specific suffix 'C' against official Microchip documentation to confirm exact tolerance and package variations, as standard 1N5533 variants may differ. Ensure compatibility with RoHS directives if required by your system specifications. Cross-reference datasheet revision dates to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a 13 V regulation point is required within a wide thermal operating range. Consider the 5% tolerance and 90 Ohm impedance for precision requirements. Evaluate the DO-204AH or equivalent package constraints for PCB layout. Compare against other series members like 1N5533B or 1N5533D if tighter tolerances or different packaging styles are necessary.

Part Context

This part belongs to the 1N55xx series of low-power Zener diodes manufactured by Microchip Technology. These components are widely used in general-purpose electronics for biasing and regulation. The series offers various voltage options ranging from approximately 3.3 V to higher values, all sharing similar power dissipation and package characteristics.

Replacement Considerations

Check for direct equivalents such as 1N5533B or 1N5533D from Microchip or other manufacturers. Verify that substitute parts match the 13 V Zener voltage, 500 mW power rating, and ±5% tolerance. Ensure the replacement package type fits the existing footprint and meets the same thermal performance standards.
