1N5535C

Single Zener Diodes Overview

The Microchip Technology 1N5535C is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a test current of 1 mA and a maximum power dissipation of 500 mW. The device exhibits a Zener impedance of 100 Ohms and a maximum reverse leakage current of 10 nA. It operates within a junction temperature range of -65 °C to +175 °C and offers a voltage tolerance of 5%. The component is available in axial leaded packages, including DO-204AH (DO-35) and surface-mount DO-213AA-2 configurations.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 15 V potential under specified test conditions.
• Capable of handling up to 500 mW of power dissipation for robust circuit protection.
• Engineered for reliable operation across an extended industrial temperature range.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 15 V stabilization
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific package variant required, as the 1N5535C designation covers both through-hole DO-35 and surface-mount DO-213AA-2 forms. Confirm suffix designations such as /TR or -1 indicate packaging or tolerance variations rather than functional changes. Ensure compatibility with assembly processes by checking RoHS status and moisture sensitivity levels against project specifications before ordering.

Single Zener Diodes Selection Notes

Select this component when a 15 V regulation point is needed with moderate precision. The 5% tolerance suits general-purpose applications where tight voltage control is not critical. Consider the 100 Ohm impedance for dynamic load requirements. Evaluate thermal management needs given the 500 mW rating and high-temperature capability. Compare against alternative Zener voltages if system requirements shift.

Single Zener Diodes Part Context

This part belongs to the standard 1N553x series of Zener diodes manufactured by Microchip Technology. The series provides various voltage options from low to high ranges, all sharing similar power handling and temperature characteristics. The 1N5535C specifically targets the 15 V segment, offering a balance between leakage performance and regulation stability for general electronic designs.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers include 1N5535BUR-1 and 1N5535D-1. Verify pinout compatibility and exact voltage tolerance matches when substituting. Ensure the replacement package type aligns with existing PCB footprints.
