Overview
The Microchip Technology 1N5531B/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 11 V with a tolerance of ±5%. The device operates in a through-hole DO-204AH (DO-35) axial leaded package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 10 nA, a Zener impedance of 80 Ohms, and a test current of 1 mA. It supports a forward current of 200 mA with a forward voltage of 1.1 V. The component is rated for an operating temperature range from -65°C to +175°C junction temperature and is supplied in a reel packaging format.
Feature Summary
- Provides stable voltage regulation at a nominal 11 V level
- Capable of handling high junction temperatures up to 175°C
- Utilizes a standard through-hole axial leaded package for easy integration
Applications
- Voltage reference circuits requiring precise regulation
- Overvoltage protection stages in electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm exact tolerance and testing parameters. Ensure the procurement channel provides valid traceability for aerospace or defense specifications if required by the design. Confirm that the reel quantity matches production needs without relying on distributor estimates.
Selection Notes
Select this component when a robust 11 V regulation point is needed within a wide thermal envelope. The DO-204AH package offers mechanical stability for through-hole mounting processes. Consider the 5% voltage tolerance and 80 Ohm impedance for circuit stability requirements compared to tighter tolerance alternatives.
Part Context
This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series is widely recognized for reliability in industrial and military-grade environments. The 'TR' suffix indicates tape and reel packaging, suitable for automated assembly processes.
Replacement Considerations
Official parameter-equivalent substitutes include JAN1N5531B-1 and JAN1N5531B-1/TR from Microchip Technology. Verify compatibility with existing board layouts and thermal constraints before substitution.
