Overview
The Microchip Technology 1N5531A/TR is a Zener diode with a nominal voltage of 11 V and a power dissipation of 500 mW. It features a 10% voltage tolerance and operates in the DO-204AH (DO-35) through-hole package. The device has a maximum reverse leakage current of 1 nA and a Zener impedance of 80 Ohms at a test current of 1 mA. It supports a wide operating temperature range from -65 °C to +175 °C and is supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation for reference circuits
- Hermetically sealed glass construction for harsh environments
- Capable of operation under severe thermal conditions
Applications
- Voltage reference applications
- Over-voltage protection circuits
- General regulation functions
Procurement Notes
Verify that the specific suffix /TR indicates tape and reel packaging rather than bulk, as this affects handling procedures. Confirm RoHS compliance status, as military variants often differ from commercial standards. Ensure the supplier provides valid traceability documentation required for aerospace or defense procurement channels.
Selection Notes
Select this component when an 11 V reference is required in a hermetic DO-35 package. Consider the 10% tolerance if tighter precision is not critical. Evaluate the 500 mW power rating against expected circuit loads to ensure safe thermal operation within the specified temperature limits.
Part Context
This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. These components are designed for high-reliability applications requiring hermetic sealing. The series offers various voltage options within the same physical package form factor.
