1N5533A

Overview

The Microchip Technology 1N5533A is a single-channel Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 13 V with a tolerance of 5%. The device operates in a surface-mount DO-213AA-2 package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 10 nA, a Zener impedance of 90 Ohms at a test current of 1 mA, and a forward voltage of 1.1 V. It supports an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation within a narrow tolerance band
• Capable of operation across extended industrial temperature ranges
• Utilizes a compact surface-mount form factor for space-constrained designs

Applications

• General voltage reference circuits
• Over-voltage protection stages
• Power supply regulation modules

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact tolerance and testing criteria. Ensure the procurement channel provides valid manufacturer traceability documentation. Confirm RoHS compliance status as indicated in the latest product change notifications. Validate that the component lot matches the required environmental screening levels for the intended application.

Selection Notes

Select this component when a precise 13 V reference is required in a small footprint. Consider the 500 mW power dissipation limit relative to ambient thermal conditions. Evaluate the 90 Ohm impedance for dynamic load requirements. Compare the -65 °C to +175 °C range against system thermal profiles to ensure reliability under extreme conditions.

Part Context

This part belongs to the standard Zener diode family offered by Microchip Technology. It serves as a discrete semiconductor solution for basic voltage clamping and referencing tasks. The component utilizes silicon junction technology encapsulated in a leadless surface-mount package suitable for automated assembly processes.

Replacement Considerations

Consult official cross-reference guides for verified equivalents. Ensure substitute parts match the 13 V nominal voltage, 5% tolerance, and 500 mW power rating. Verify package compatibility with the DO-213AA-2 footprint.
