Product details

75 V, 195 A — the conduction-loss floor for high-current switching

The IRFS7730TRLPBF is an N-channel MOSFET from Infineon's HEXFET and StrongIRFET series, built for applications where the rail voltage sits at 75 V and the continuous drain current reaches 195 A at the case.

Gate charge and the driver it demands

The D²PAK surface-mount package with the exposed tab is the thermal bottleneck. A two-layer board with a minimal copper pour will hit the thermal limit well before the 375 W case rating suggests.

Frequently asked questions

What is the IRFS7730TRLPBF datasheet?

Design engineers need the datasheet to validate electrical parameters and ensure fit for their circuit.

Where to buy IRFS7730TRLPBF?

Sourcing buyers need to find authorized distributors and check stock availability to fill BOM lines.

What is the price of IRFS7730TRLPBF?

Pricing directly impacts procurement decisions and budget planning for manufacturing.

Is IRFS7730TRLPBF obsolete or active?

Brokers and buyers must know lifecycle status to avoid supply chain disruptions or end-of-life risks.

What is the replacement for IRFS7730TRLPBF?

When the part is unavailable or EOL, engineers need a drop-in alternative to maintain design continuity.

What is the pinout of IRFS7730TRLPBF?

Maintenance techs replacing a failed unit need pin compatibility with the existing PCB footprint.
