Overview
The Microchip Technology 1N4942E3 is a fast recovery rectifier diode designed for through-hole mounting. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1 A. The device exhibits a typical forward voltage drop of 1.3 V at rated current and a maximum reverse leakage current of 1 µA. Its fast recovery time is specified at 150 ns, supporting efficient switching operations. The component operates within a junction temperature range of -65°C to +175°C and utilizes the DO-41 axial package.
Feature Summary
- Fast recovery characteristics with a 150 ns switching time for high-frequency applications
- Wide thermal operating range extending up to 175°C junction temperature
- High surge current capability to withstand transient overload conditions
Applications
- High-frequency rectification in power supply circuits
- Free-wheeling diodes in inductive load protection
- General-purpose rectification in electronic equipment
Procurement Notes
Verify that the ordering suffix E3 confirms lead-free construction and RoHS compliance as per manufacturer specifications. Confirm the package type matches the required axial lead configuration for your PCB layout. Ensure the voltage and current ratings align with your circuit's peak operational demands before finalizing procurement.
Selection Notes
Select this component when a standard fast recovery rectifier is required for low-to-medium current applications. The 1N4942E3 serves as a lead-free alternative to non-E3 variants, maintaining identical electrical performance while meeting environmental directives. Consider its 200 V rating and 1 A capacity against your specific circuit requirements.
Part Context
This part belongs to the 1N49xx series of fast recovery rectifiers manufactured by Microchip Technology. The E3 suffix indicates a lead-free terminal finish compliant with RoHS standards. It shares the same electrical profile as the standard 1N4942 but adheres to modern environmental manufacturing guidelines for global deployment.
Replacement Considerations
Direct substitutes include the JAN1N4942 for military-grade specifications or other 1N4942 variants from different manufacturers providing identical 200V/1A fast recovery characteristics. Verify pinout compatibility and thermal management requirements when cross-referencing.
