Overview
The Microchip Technology 1N5528A is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 8.2 V with a tolerance of ±10%. The device has a maximum power dissipation of 500 mW and operates in the DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 6.5 V, a forward voltage of 1.1 V at 200 mA, and an operating junction temperature range from -65°C to 175°C.
Feature Summary
- Provides stable voltage regulation with a nominal 8.2 V output.
- Supports high-temperature operation up to 175°C junction temperature.
- Utilizes a standard axial through-hole package for easy integration.
Applications
- Voltage reference circuits
- Overvoltage protection
- General-purpose voltage regulation
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package type matches DO-204AH specifications. Ensure storage conditions prevent moisture damage prior to soldering. Review environmental compliance documentation such as REACH status before procurement.
Selection Notes
Select this component when a fixed 8.2 V reference is required in through-hole designs. Consider the ±10% tolerance for budget applications. Evaluate thermal management needs given the 500 mW power rating. Compare leakage current specifications against circuit sensitivity requirements.
Part Context
This part belongs to the 1N5528 series of Zener diodes manufactured by Microchip Technology. It shares functional similarities with other axial leaded Zener diodes but offers specific performance metrics defined by the manufacturer. The series supports various tolerance grades including A and B variants.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include the CDLL5528A in surface mount packaging. Other compatible options may exist within the same voltage class, though package differences must be addressed during implementation.
