Overview
The Microchip Technology 1N4624DUR-1 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a maximum impedance of 1550 Ohms. The device operates within a power dissipation rating of 500 mW and maintains a low reverse leakage current of 5 µA at 3 V. It is housed in a DO-213AA surface-mount package, suitable for compact circuit designs requiring stable reference voltages.
Feature Summary
- Provides precise voltage regulation with a 4.7 V nominal Zener potential
- Utilizes a metallurgically bonded glass construction for durability
- Supports surface-mount installation via the DO-213AA package format
Applications
- Voltage reference circuits
- Overvoltage protection stages
- Clamping applications in signal paths
Procurement Notes
Verify the specific suffix and tolerance grade against the original design specification sheet. Confirm that the DO-213AA footprint matches the PCB layout requirements. Ensure the manufacturer's datasheet is consulted for thermal derating curves and absolute maximum ratings prior to final integration into the system architecture.
Selection Notes
Select this component when a surface-mount Zener regulator is required for low-power voltage clamping. The 500 mW rating suits general-purpose regulation tasks. Compare the 1550 Ohm impedance against load requirements to ensure adequate regulation performance under varying current conditions within the specified operating temperature range.
Part Context
This part belongs to the 1N4624 series of Zener diodes manufactured by Microchip Technology. It serves as a surface-mount alternative to through-hole variants, offering similar electrical characteristics in a compact form factor. The series is commonly used in consumer electronics and industrial control systems where space constraints dictate the use of small outline packages.
Replacement Considerations
Equivalent parts include JAN1N4624UR-1 and 1N4624-1E3/TR. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement meets the same voltage tolerance and power dissipation specifications.
