1F1G-TP

Overview

The 1F1G-TP is a fast recovery rectifier manufactured by Micro Commercial Components (MCC). It features a 1 A average forward current and a 50 V repetitive peak reverse voltage. The device utilizes an R-1 (DO-41) through-hole package. Key electrical characteristics include a maximum forward voltage of 1.2 V at 1 A, a reverse leakage current of 5 µA at 50 V, and a typical reverse recovery time of 50 ns. The component supports a maximum surge current of 30 A and operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Fast recovery performance with a typical reverse recovery time of 50 ns for efficient switching applications.
• High thermal stability with a maximum operating junction temperature of +175°C.
• Robust surge handling capability rated at 30 A for transient protection.

Applications

• High-frequency DC-DC converter circuits
• Free-wheeling diodes in power supplies
• General-purpose rectification in consumer electronics

Procurement Notes

Verify the NRND status before design finalization, as this component is not recommended for new designs. Confirm that the R-1 through-hole package aligns with your PCB layout requirements. Ensure the 50 V reverse voltage rating meets the specific circuit's peak inverse voltage demands. Check for updated datasheets to confirm any recent parameter revisions or environmental compliance updates prior to procurement.

Selection Notes

Select this component when a through-hole fast recovery diode is required for low-voltage, high-current applications. The 1 A current rating suits moderate power levels, while the 50 ns recovery time addresses efficiency needs in switching regulators. Consider the +175°C junction temperature for high-temperature environments. Evaluate the physical size constraints of the R-1 package against available board space.

Part Context

The 1F1G-TP belongs to MCC's HER series of high-efficiency rectifiers. It is designed to replace standard silicon rectifiers in applications requiring faster switching speeds. The part is commonly used in power supply designs where compact through-hole solutions are preferred over surface-mount alternatives. It complements other MCC diodes like the SM4934A-TP for different packaging needs.

Replacement Considerations

Publicly confirmed substitutes include the FS1G-LTP from Micro Commercial Components. Designers should verify pin compatibility and electrical parameters when substituting.
