Overview
The Microchip Technology 1N4912A is a general-purpose silicon rectifier diode designed for high-voltage applications. It features a maximum repetitive peak reverse voltage of 1000V and a continuous forward current rating of 1.0A at 75°C. The device utilizes a DO-41 axial leaded package, providing robust mechanical stability for through-hole mounting. Key electrical characteristics include a low forward voltage drop of approximately 1.1V at rated current and a fast recovery time of 75ns, making it suitable for various power supply and inverter circuits.
Feature Summary
- High voltage blocking capability for demanding circuit environments
- Robust axial leaded construction for reliable through-hole integration
- Fast recovery characteristics for efficient switching operations
Applications
- General purpose rectification in power supplies
- Inverter circuits requiring high voltage tolerance
- Protection against reverse polarity in DC circuits
Procurement Notes
Verify the specific datasheet revision and manufacturer lot codes upon procurement to ensure compliance with current specifications. Confirm that the component meets all required environmental standards and packaging formats specified by your design requirements before finalizing orders.
Selection Notes
Select this component when a 1000V reverse voltage rating and 1A forward current capacity are required. Ensure the operating temperature range aligns with the specified -65°C to 175°C junction temperature limits. Consider the DO-41 package dimensions for PCB layout compatibility.
Part Context
This part belongs to the standard 1N49xx series of silicon rectifier diodes manufactured by Microchip Technology. These components are widely used in industrial and consumer electronics for basic rectification tasks. The 1N4912A specifically offers higher voltage ratings compared to lower-numbered variants in the same series.
Replacement Considerations
Equivalent parts include the 1N4007 or 1N539x series diodes from other manufacturers, provided they meet the 1000V and 1A specifications. Verify pinout compatibility and thermal performance before substitution.
