IRF720S

Single FETs, MOSFETs Overview

The IRF720S is a third-generation N-Channel Power MOSFET from Vishay Siliconix, housed in a surface-mount D2PAK (TO-263) package. It features a 400 V drain-source voltage rating and a maximum continuous drain current of 3.3 A at a case temperature of 25 °C. The device exhibits a maximum on-resistance of 1.8 Ω at VGS = 10 V and supports a pulsed drain current of 13 A. Key electrical parameters include a total gate charge of 20 nC, a single pulse avalanche energy rating of 190 mJ, and a peak diode recovery dv/dt of 4.0 V/ns.

Single FETs, MOSFETs Feature Summary

• Surface-mount construction in a D2PAK (TO-263) package designed for high-current applications with low internal connection resistance.
• Dynamic dv/dt rating capability to manage fast switching transitions and prevent false turn-on events.
• Repetitive avalanche rated design ensuring ruggedized performance under inductive load switching conditions.
• Optimized for ease of paralleling and simple drive requirements due to consistent switching characteristics.

Single FETs, MOSFETs Applications

• High-voltage power conversion circuits
• DC-DC converter topologies requiring robust switching elements
• Industrial motor control systems

Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix when purchasing to ensure compliance with material regulations. Suffixes such as -GE3 indicate lead-free and halogen-free status, while PbF variants denote standard lead terminations. Confirm that the selected variant matches the required termination type for the intended assembly process and environmental compliance standards.

Single FETs, MOSFETs Selection Notes

Select this component for designs requiring a 400 V breakdown voltage in a surface-mount form factor. Evaluate thermal management strategies carefully, as the maximum power dissipation drops significantly when mounted on a PCB compared to direct case cooling. Ensure the gate drive circuitry can handle the specified gate charge within the desired switching frequency constraints.

Single FETs, MOSFETs Part Context

This part belongs to the Vishay Siliconix third-generation Power MOSFET family, which combines fast switching speeds with low on-resistance. The D2PAK package allows for higher power capability than smaller surface-mount options by accommodating larger die sizes. It serves as a bridge between through-hole reliability and surface-mount convenience for medium-power applications.

Single FETs, MOSFETs Replacement Considerations

The SiHF720S is a lead-free and halogen-free equivalent offering identical electrical specifications. For through-hole implementations, the IRF720L or SiHF720L in the I2PAK (TO-262) package provides comparable performance with a different mounting style.
