Overview
The Microchip Technology 1N5522A is a single Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and utilizes the DO-204AH (DO-35) axial through-hole package. Electrical characteristics include a reverse leakage current of 2 µA at 1.5 V and a forward voltage of 1.1 V at 200 mA. It operates within a junction temperature range of -65°C to 175°C.
Feature Summary
- Provides stable voltage regulation with a nominal 4.7 V Zener potential.
- Supports high-temperature operation up to 175°C junction temperature.
- Utilizes a standard axial leaded package for through-hole mounting.
Applications
- Voltage reference circuits
- Overvoltage protection
- General-purpose voltage regulation
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number and date codes against official Microchip documentation. Confirm that the received devices match the specified DO-204AH package and electrical tolerances. Ensure compliance with relevant environmental standards such as REACH status before integration into final assemblies.
Selection Notes
Select this component when a precise 4.7 V reference is required in through-hole designs. Consider the ±10% tolerance and 500 mW power rating to ensure adequate margin for thermal management. Verify that the axial form factor fits the PCB layout constraints compared to surface-mount alternatives.
Part Context
This component belongs to the Microchip Technology discrete semiconductor product line, specifically within the Zener diode category. It is manufactured under the 1N55xx series designation, which defines specific voltage and power characteristics for general-purpose electronic applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official distributor databases or Microchip engineering support for verified equivalent components if sourcing constraints exist.
