Overview
The Microchip Technology 1N4626UR is a Zener voltage regulator diode designed for surface-mount applications. It features a nominal Zener voltage of 5.6 V with a standard tolerance of 5%. The device operates within a power dissipation rating of 0.5 W and utilizes the DO-213AA (MLL4626) package. Key electrical characteristics include a maximum reverse leakage current of 1400 Ohms impedance at specified test conditions, ensuring stable regulation in low-current circuits.
Feature Summary
- Provides precise voltage regulation using metallurgically bonded glass surface mount construction
- Offers high thermal stability suitable for demanding operating environments
- Ensures reliable performance through internal-metallurgical-bond package technology
Applications
- Voltage reference circuits requiring stable low-voltage sources
- Overvoltage protection stages in sensitive electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix UR against official Microchip documentation to confirm tape-and-reel packaging and lead-free compliance. Ensure the DO-213AA footprint matches your PCB design constraints. Cross-reference the MIL-PRF-19500/435 series requirements if military-grade qualification is necessary for your application.
Selection Notes
Select this component when a compact surface-mount solution is required for 5.6 V regulation. Compare the 1400 Ohm impedance against circuit sensitivity needs. Verify that the 0.5 W power rating accommodates peak dissipation scenarios without exceeding the maximum junction temperature limits defined in the datasheet.
Part Context
This part belongs to the 1N46xx series of 0.5 watt glass surface mount Zener diodes manufactured by Microchip Technology. The series covers a wide voltage range from 1.8 to 100 volts. The UR designation typically indicates a specific reel packaging format for automated assembly processes.
Replacement Considerations
Check for direct equivalents such as JAN1N4626-1 or MLL4626-1 which share the same DO-213AA footprint and electrical specifications. Ensure any substitute maintains the 5.6 V nominal voltage and 5% tolerance to preserve circuit functionality.
