Overview
The Microchip Technology 1N4625D/TR is a general-purpose silicon rectifier diode designed for low-voltage, high-current applications. It features a standard axial leaded package suitable for through-hole mounting on printed circuit boards. The device provides reliable reverse blocking capabilities and forward conduction characteristics typical of small-signal rectifiers. This component is engineered to handle repetitive peak forward current and withstand specified reverse voltage levels under defined thermal conditions.
Feature Summary
- Standard axial leaded construction for robust mechanical mounting
- Silicon planar dielectric isolation technology
- High surge current capability for transient protection
Applications
- General purpose rectification in power supplies
- Reverse polarity protection circuits
- Clamping and flyback diode applications
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging configuration rather than bulk packaging when reviewing distributor listings. Confirm the manufacturer datasheet matches the exact part number to ensure correct electrical ratings and physical dimensions. Cross-reference with official Microchip documentation to validate authenticity and lot traceability requirements before procurement.
Selection Notes
Select this component when a standard silicon rectifier with axial leads is required for low-frequency AC-to-DC conversion or DC blocking. Ensure the operating temperature range and maximum reverse voltage align with the circuit design specifications. Consider the package size constraints and thermal dissipation needs relative to the expected forward current load in the final assembly.
Part Context
This part belongs to the 1N462x series of small-signal silicon rectifier diodes manufactured by Microchip Technology. These components are widely used in consumer electronics and industrial control systems where reliable switching and rectification are necessary. The series offers consistent performance across various environmental conditions, supporting diverse electronic design implementations.
Replacement Considerations
Equivalent parts include other 1N4625 variants from different manufacturers such as ON Semiconductor or Vishay, provided they meet identical electrical specifications and package dimensions. Verify pinout compatibility and thermal characteristics before substitution to ensure circuit integrity.
