Overview
The 1N5526/TR is a single silicon Zener diode manufactured by Microchip Technology. It provides a nominal Zener voltage of 6.8V with a tolerance of 5%. The device operates in the through-hole DO-35-2 package and dissipates up to 500mW. Key electrical characteristics include a maximum reverse leakage current of 100nA, a Zener impedance of 30 Ohms at a test current of 1mA, and a forward voltage of 1.5V. It functions within an extended temperature range from -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Capable of operation across extreme industrial temperature ranges
- Features low reverse leakage current for high-impedance applications
Applications
- Precision voltage reference circuits
- Overvoltage protection stages
- Biasing networks in analog signal processing
Procurement Notes
Verify component authenticity through authorized Microchip channels or certified distributors. Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure all handling procedures comply with electrostatic discharge standards during assembly to maintain device integrity and performance specifications.
Selection Notes
Select this component when a 6.8V regulation point is required in a compact axial leaded form factor. Consider the 5% voltage tolerance and 30 Ohm impedance against circuit sensitivity requirements. Evaluate the thermal management needs relative to the 500mW power dissipation limit under worst-case operating conditions.
Part Context
This part belongs to the standard 1N55xx series of Zener diodes produced by Microchip Technology. It utilizes the legacy MIL-spec numbering convention adapted for commercial and industrial manufacturing. The device represents a fundamental discrete semiconductor component used widely in electronic design for basic voltage control tasks.
Replacement Considerations
Substitute with JAN1N5526DUR-1 for surface mount MELF compatibility. Use 1N5526B/TR for identical electrical performance in bulk packaging. Verify pinout and thermal characteristics match before implementing any cross-reference.
