Overview
The Microchip Technology 1N5528A/TR is a single Zener diode designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a ±10% tolerance and a maximum power dissipation of 500 mW. The device utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 6.5 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 an 8.2 V nominal breakdown voltage.
- Capable of handling up to 500 mW of power dissipation in a compact form factor.
- Engineered for reliable operation across a wide industrial temperature range.
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- General-purpose voltage regulation tasks
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging versus bulk options. Confirm RoHS compliance status, as historical data indicates variations within the 1N5528 series. Ensure the selected variant matches the required lead frame material and marking codes for your assembly process.
Selection Notes
Select this component when an 8.2 V regulation point is required in a through-hole configuration. Compare the ±10% tolerance against tighter precision requirements that might necessitate the 'B' suffix variant. Evaluate the 500 mW power rating against circuit load conditions to ensure adequate thermal headroom during continuous operation.
Part Context
This part belongs to the standard 1N5528 series of glass-passivated Zener diodes manufactured by Microchip Technology. The series covers a broad range of voltage values from 2.4 V to 75 V, all sharing similar mechanical dimensions and power handling capabilities in the DO-35 package style.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include the 1N5528B and 1N5528C variants from Microchip Technology. Other manufacturers may offer compatible parts under different numbering schemes, but direct cross-reference requires verifying identical voltage, power, and package specifications.
