Product details

Package and mounting

The Infineon IRFS7537TRLPBF is a 60 V, 173 A N-channel MOSFET from the HEXFET® StrongIRFET™ series, housed in a surface-mount D²Pak (TO-263-3) with the exposed tab for thermal transfer to the board copper. Gate charge is 210 nC at 10 V; plan the gate-driver current budget around that figure at the target switching frequency.

Thermal and voltage headroom for 48 V bus designs

With a 60 V drain-source rating, this MOSFET carries comfortable margin for 48 V nominal systems (54 V peak under float) — the 60 V Vdss covers transients without avalanche stress. The D²Pak footprint uses the large copper pad on the PCB as the primary heatsink — the thermal vias under the tab are not optional for sustained 100 A+ loads.

Frequently asked questions

Can I use IRFS7537TRLPBF in a 48V system?

Yes. The 60 V drain-source rating provides adequate headroom for 48 V nominal systems, including transient peaks up to 54 V.
