Product details
Overview
IRFSL7537PBF from International Rectifier is a N-channel power MOSFET for switching, load-control, and power-conversion circuits supplied in the TO-262-3 Long Leads, I2PAK, TO-262AA package. The device is intended for discrete power switching where board designers need a defined MOSFET package, gate-control interface, drain-source current path, and thermal path.
For engineers reviewing the IRFSL7537PBF datasheet, IRFSL7537PBF pinout, IRFSL7537PBF application, or IRFSL7537PBF equivalent, this device is commonly used in automotive load switching, motor control, relay and solenoid switching, DC-DC converter stages, battery power paths, and legacy power-board replacement. Selection should focus on channel polarity, drain-source voltage, continuous and pulsed current, RDS(on), gate charge, body-diode behavior, package thermal resistance, and footprint compatibility.
Technical Context
In circuit use, IRFSL7537PBF serves as the main discrete switching element between the supply, load, or converter node and the power return or power rail.
The gate driver should be selected from the required gate voltage, total gate charge, switching speed, and EMI target. RDS(on), pulsed current, avalanche capability, and body-diode recovery define practical load and converter limits.
The I²Pak / TO-262 package determines the board footprint, heat-spreading path, and current terminal arrangement. For replacement work, the package and pinout should be confirmed before assuming interchangeability with another IRF or AUIRF suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | N-channel power MOSFET for switching, load-control, and power-conversion circuits. |
| Package | TO-262-3 Long Leads, I2PAK, TO-262AA; I²Pak long-lead power package for board-mounted switching stages requiring higher current paths than small SMD packages. |
| Channel / Polarity | N-channel power MOSFET; polarity and body-diode orientation must match the original power stage. |
| Gate-Drive Class | Gate-drive voltage should be selected from the RDS(on) test condition and switching-loss target. |
| On-Resistance Review | RDS(on), package temperature rise, and PCB copper area define conduction loss under continuous load current. |
| Switching Parameter Review | Gate charge, input capacitance, output capacitance, and reverse-recovery behavior affect driver selection and switching frequency. |
| Avalanche / Inductive Load Review | Single-pulse avalanche rating, repetitive stress, and body-diode use should be checked for inductive or motor-load circuits. |
| Thermal Design | I²Pak / TO-262 thermal path should be evaluated with the actual copper area, airflow, heatsink, and duty cycle. |
Pinout & Package
The IRFSL7537PBF pinout should be checked together with the TO-262-3 Long Leads, I2PAK, TO-262AA outline, because terminal arrangement and thermal connection affect layout, replacement approval, and assembly method.
For PCB design, keep the high-current power path short, route the gate or control line away from noisy switching nodes, and size copper or heatsinking for the real load current and duty cycle. I²Pak long-lead power package for board-mounted switching stages requiring higher current paths than small SMD packages.
| Pin / Function | PCB Design and Circuit Role |
|---|---|
| Gate | MOSFET control terminal; selected drive voltage, gate resistance, and driver strength affect switching loss and EMI. |
| Drain / Tab | Main power terminal tied to the package tab in many power packages; use adequate copper area or heatsinking for heat spreading. |
| Source | Power return terminal; route with low resistance and low inductance to reduce loss and switching overshoot. |
| Package Body | I²Pak / TO-262 package: I²Pak long-lead power package for board-mounted switching stages requiring higher current paths than small SMD packages. |
