Overview
The 1F4G-TP is a general-purpose fast recovery rectifier diode manufactured by Micro Commercial Components (MCC). It features a maximum average forward rectified current of 1A and a repetitive peak reverse voltage of 400V. The device utilizes an R-1 axial leaded package, suitable for through-hole mounting applications. Designed for high-speed switching, it offers fast recovery characteristics to minimize reverse recovery time in power supply and conversion circuits.
Feature Summary
- Fast recovery performance for efficient high-speed switching operations
- General-purpose design suitable for broad electronic applications
- Robust 1A current handling capability with 400V reverse voltage rating
Applications
- High-frequency rectification in DC-DC converters
- Free-wheeling diodes in inductive load circuits
- General-purpose rectification in consumer electronics power supplies
Procurement Notes
Verify the component marking matches the 1F4G-TP designation exactly. Confirm the manufacturer is Micro Commercial Components (MCC) to ensure authenticity. Check for physical damage to the axial leads and the integrity of the plastic encapsulation before integration into circuit boards.
Selection Notes
Select this component when a 1A current rating and 400V blocking voltage are required in an axial package. Ensure the application demands fast recovery characteristics rather than standard soft recovery. Verify that the thermal management requirements align with the R-1 package's dissipation capabilities.
Part Context
This part belongs to MCC's discrete semiconductor portfolio, specifically within their rectifier and diode lines. It complements other fast recovery devices like the UG1B-TP series, offering similar functionality with different voltage ratings. The product line targets consumer and industrial markets requiring reliable, high-quality discrete components.
Replacement Considerations
Potential substitutes include other 1A, 400V fast recovery diodes in axial packages from manufacturers such as Vishay or ON Semiconductor. Ensure replacement parts match the pinout, recovery time specifications, and thermal characteristics of the original 1F4G-TP.
