KGF65A4H

Overview

The KGF65A4H is a 650 V Field Stop IGBT manufactured by Sanken Electric, utilizing an original trench structure to decrease gate capacitance and achieve high-speed switching. It integrates a fast recovery diode and supports a continuous collector current of 40 A at TC = 100 °C. The device features a short circuit withstand time of 10 μs, with typical saturation voltage (VCE(sat)) of 1.9 V and reverse recovery time (tf) of 60 ns at TJ = 175 °C. It is housed in a TO247-3L package and complies with RoHS standards.

Feature Summary

• Sanken original trench structure decreases gate capacitance for high-speed switching
• Integrated fast recovery diode reduces switching loss
• RoHS compliant construction

Applications

• Welding Converters
• PFC Circuit

Procurement Notes

Verify the component status before procurement as the datasheet explicitly states this model is not recommended for new designs. Confirm that the TO247-3L package variant matches your board layout requirements. Ensure compliance with the specified soldering limits: flow soldering at 260 ± 5 °C for 10 ± 1 seconds or iron soldering at 380 ± 10 °C for 3.5 ± 0.5 seconds. Maintain a minimum distance of 1.5 mm from the body during soldering operations.

Selection Notes

Select the KGF65A4H when a 650 V rating and 40 A continuous current capability are required in a TO247-3L package. Consider the MGF65A4H or FGF65A4H if alternative mounting styles like TO3P-3L or TO3PF-3L are needed instead. Evaluate thermal resistance values carefully, as junction-to-case resistance varies between 0.52 °C/W and 2.08 °C/W depending on the specific package configuration chosen.

Part Context

The KGF65A4H belongs to the xGF65A4H series alongside the MGF65A4H and FGF65A4H models. These components share identical electrical characteristics but differ in physical packaging. The series utilizes Sanken's proprietary trench field stop technology to optimize efficiency through reduced gate capacitance and lower switching losses compared to standard planar structures.

Replacement Considerations

Public confirmed substitute part numbers include MGF65A4H and FGF65A4H. These variants offer identical electrical performance but utilize different packages (TO3P-3L and TO3PF-3L respectively). Verify mechanical footprint compatibility before substitution.
