Overview
The MCC 1N4947-TP is a fast recovery rectifier diode housed in the DO-41 axial leaded package. It features a maximum repetitive peak reverse voltage of 800V and an average forward rectified current rating of 1.0A at 55°C ambient temperature. The device exhibits a maximum instantaneous forward voltage of 1.3V at 1.0A and a maximum DC reverse current of 5.0μA at rated voltage and 25°C junction temperature. Its maximum reverse recovery time is specified at 250ns, with a typical junction capacitance of 15pF measured at 1.0MHz.
Feature Summary
- Fast switching capability with low leakage current for high efficiency applications
- Epoxy casing meets UL 94 V-0 flammability rating standards
- Lead-free finish compliant with RoHS directives
Applications
- High frequency rectification circuits
- Free-wheeling diodes in power supplies
- General purpose rectification in industrial equipment
Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm the specific suffix matches the required packaging type, such as -TP for tape and reel or -AP for ammo packing. Ensure compliance with environmental regulations like RoHS if halogen-free variants are needed.
Selection Notes
Select this component when a 800V blocking voltage and 1A continuous current capacity are required. The 250ns reverse recovery time makes it suitable for faster switching applications compared to standard rectifiers. Verify thermal management requirements as the maximum thermal resistance is 50°C/W junction to ambient.
Part Context
This part belongs to the 1N4942 through 1N4948 series of fast recovery rectifiers manufactured by Micro Commercial Components. The series covers reverse voltage ratings from 200V to 1000V while maintaining a consistent 1.0A average forward current rating across all variants.
Replacement Considerations
Direct substitutes include other manufacturers' 1N4947 equivalents meeting identical electrical specifications. Cross-reference with generic fast recovery rectifiers offering 800V reverse voltage and 1A forward current in a DO-41 package.
