Overview
The Microchip Technology 1N4942E3/TR is a single fast recovery rectifier diode designed for through-hole mounting in the A-Package-2 (DO-35) form factor. It features a maximum repetitive reverse voltage of 200 V and a continuous forward current rating of 1 A. The device exhibits a peak non-repetitive forward surge current capacity of 15 A, with a maximum forward voltage drop of 1.3 V at rated current. Key electrical characteristics include a reverse leakage current of 1 µA and a peak reverse recovery time of 150 ns. It operates within a temperature range of -65°C to +175°C.
Feature Summary
- Fast recovery performance suitable for high-frequency switching applications
- Glass passivated junction construction for enhanced reliability
- Wide operating temperature range supporting extreme environmental conditions
Applications
- High frequency rectification circuits
- Free wheeling diodes in power supplies
- General purpose rectification in industrial electronics
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology, noting its acquisition history involving Micrel. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the datasheet for exact mechanical dimensions to validate PCB footprint compatibility before finalizing procurement.
Selection Notes
Select this component for applications requiring fast recovery times under 150 ns with a 200 V blocking capability. It serves as a direct replacement for standard 1N4942 variants in through-hole designs. Consider the 1 A current rating and 175°C thermal limit for circuit design margins. Verify package compatibility with existing manufacturing equipment if transitioning from other suppliers.
Part Context
This part belongs to the 1N494x series of glass passivated junction fast recovery rectifiers. It shares functional similarities with other members of the family but is distinguished by its specific 200 V reverse voltage rating. The E3 suffix denotes lead-free and halogen-free construction compliant with international environmental directives.
Replacement Considerations
Direct substitutes include the 1N4942 and 1N4942G. Other compatible options are the 1N4942E3 and 1N4942M. Verify pinout and thermal characteristics match when substituting.
