Overview
The MCC 1N4942-TP is a fast recovery rectifier diode housed in the DO-41 axial leaded package. It supports an average forward current of 1.0 A at 55°C and withstands a maximum repetitive peak reverse voltage of 200 V. The device features a maximum instantaneous forward voltage of 1.3 V at 1.0 A and a typical junction capacitance of 15 pF. Reverse recovery time is specified at 150 ns under defined test conditions, with a maximum DC reverse leakage current of 5.0 μA at rated voltage.
Feature Summary
- Fast switching capability with low leakage current
- High temperature metallurgically bonded construction
- Glass passivated cavity-free junction design
Applications
- General purpose rectification in power supplies
- Free wheeling diode applications
- Low leakage current circuits
Procurement Notes
Verify the specific ordering suffix to confirm packaging format and compliance status. The -TP suffix indicates tape and reel packaging containing 5,000 pieces per reel. Confirm RoHS compliance and halogen-free availability if required by project specifications. Ensure procurement from authorized distributors to guarantee genuine parts and full traceability.
Selection Notes
Select this component for applications requiring 200 V reverse blocking capability and 1 A continuous forward current. The 150 ns reverse recovery time makes it suitable for general-purpose rectification where standard recovery speeds are insufficient. Verify thermal derating requirements based on ambient operating temperatures exceeding 55°C.
Part Context
This part belongs to the 1N4942 through 1N4948 series of 1 Amp Fast Recovery Rectifiers manufactured by Micro Commercial Components. The series covers reverse voltage ratings from 200 V to 1000 V within the same DO-41 package form factor. The 1N4942 specifically addresses the lower end of the voltage range in this family.
Replacement Considerations
Cross-reference with other manufacturers' 1N4942 equivalents or 1N400x series diodes if reverse recovery speed is not critical. Verify pinout compatibility and package dimensions when substituting.
