Product details
Overview
IRF7353D2TRPBF from Infineon Technologies (formerly International Rectifier) is a 30V, 4.8A, n-channel D²Pak (TO-263) MOSFET with 42mΩ RDS(on) at VGS = 10V, optimized for DC-DC converters and load switching in industrial power supplies.
For engineers reviewing the IRF7353D2TRPBF datasheet, IRF7353D2TRPBF pinout, IRF7353D2TRPBF application, or IRF7353D2TRPBF equivalent, key selection criteria include its low gate charge (12nC), fast turn-on/turn-off times (12ns/25ns), and thermal resistance (RθJA = 62°C/W) in surface-mount D²Pak packaging.
Technical Context
This MOSFET employs a Generation 3 HEXFET silicon process with planar vertical DMOS architecture, enabling stable operation up to TJ = 175°C. Its threshold voltage (VGS(th)) ranges from 1.0V to 2.0V, supporting direct microcontroller drive without level-shifting in low-voltage logic interfaces.
The device features an integrated body diode with reverse recovery time (trr) of 35ns and Qrr of 22nC, suitable for synchronous rectification and freewheeling in buck and flyback topologies where diode conduction loss must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30V - Maximum drain-source blocking voltage for 24V rail applications with margin. |
| RDS(on) @ VGS=10V | 42mΩ - Conduction loss of ~1.0W at 5A continuous drain current. |
| ID (continuous) | 4.8A - Sustained current capability at TC = 25°C with heatsinking. |
| Qg | 12nC - Gate charge enabling efficient 500kHz PWM switching with low driver power. |
| ton/toff | 12ns / 25ns - Fast switching reduces overlap loss in hard-switched converters. |
| RθJA | 62°C/W - Thermal resistance defining junction-to-ambient temperature rise on standard 1-in² 2-oz copper PCB. |
Pinout & Package
IRF7353D2TRPBF is housed in a surface-mount D²Pak (TO-263) package with three terminals: Drain (tab), Source (pin 1), and Gate (pin 2). The exposed drain pad provides low-inductance, high-current path and serves as primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current-carrying terminal, electrically connected to package backside | Must be soldered to large copper pour for thermal and electrical performance; not isolated. |
| Source (Pin 1) | Reference node for gate drive and current return path | Low-inductance connection critical for minimizing gate oscillation during switching. |
| Gate (Pin 2) | Control electrode for channel formation | Requires <12nC charge for full enhancement; sensitive to ESD-requires proper handling. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 10V drive | 42mΩ enables <1W conduction loss at 5A in compact 24V DC-DC modules. |
| Fast switching speed | 12ns ton/25ns toff supports >300kHz operation with minimal switching loss. |
| Enhancement-mode n-channel | VGS(th) = 1.0–2.0V allows direct drive from 3.3V/5V microcontrollers without gate driver IC. |
| Surface-mount D²Pak | TO-263 outline offers superior thermal dissipation vs. SO-8 while maintaining automated assembly compatibility. |
Applications
| DC-DC Buck Converter | Industrial Load Switch |
|---|---|
Use Scenario: Step-down regulation from 24V input to 5V/3.3V for PLC I/O modules. IC Role / Device Role: High-side synchronous rectifier switch in continuous conduction mode (CCM). Use Value: 42mΩ RDS(on) and 12nC Qg reduce total power loss by 18% versus comparable 60mΩ MOSFETs at 4A load. | Use Scenario: Controlled 12V/24V power delivery to motor drivers and solenoids in factory automation panels. IC Role / Device Role: Low-side load switch with overcurrent protection via external sense resistor. Use Value: 4.8A rating and 62°C/W RθJA allow reliable operation at 70°C ambient without forced air cooling. |
| LED Driver Power Stage | Hot-Swap Controller |
Use Scenario: Constant-current LED string control in architectural lighting fixtures with 24V bus. IC Role / Device Role: PWM-controlled current sink in linear + switching hybrid topology. Use Value: Fast ton/toff ensures clean dimming waveforms up to 20kHz without audible noise. | Use Scenario: Inrush current limiting during board insertion into live backplane (e.g., telecom shelf). IC Role / Device Role: External pass element controlled by dedicated hot-swap IC (e.g., LTC4215). Use Value: Low Qg and robust SOA enable controlled 50ms soft-start ramp without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar n-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLZ44NPBF | RDS(on) = 25mΩ @ VGS = 5V; higher gate charge (44nC); same D²Pak package | Better for 3.3V/5V logic drive but less efficient at high-frequency switching due to higher Qg | Choose when gate drive voltage is limited to ≤5V and switching frequency <200kHz. |
| STP30NF20 | VDS = 200V; RDS(on) = 45mΩ @ 10V; TO-220 package; higher RθJA (65°C/W) | Suitable for higher-voltage 48V systems but requires through-hole assembly and larger heatsink area | Choose only if 200V blocking is required and surface-mount constraint is relaxed. |
Compared with IRLZ44NPBF and STP30NF20, IRF7353D2TRPBF delivers optimal balance of low RDS(on), fast switching, and D²Pak thermal performance for 24–30V industrial DC-DC and load-switching designs requiring automated assembly.

FAQ
What is the maximum junction temperature for IRF7353D2TRPBF?
The absolute maximum junction temperature is 175°C, validated per JEDEC JESD22-A108. Operation above 150°C requires derating of continuous current based on PCB thermal design and ambient conditions. Thermal shutdown is not built-in; external monitoring is required for safety-critical applications.
Does IRF7353D2TRPBF have avalanche capability?
Yes, it is rated for repetitive avalanche energy (EAS) of 12mJ at TJ = 25°C, tested per JEDEC JESD22-A112. This supports limited inductive switching stress but does not replace snubber design in high-energy circuits like motor drives or relay coils.
Can IRF7353D2TRPBF be used in parallel configurations?
Yes, its positive temperature coefficient of RDS(on) enables current sharing across paralleled units. However, layout symmetry, gate drive impedance matching, and individual source inductance balancing are mandatory to prevent thermal runaway at high currents (>10A aggregate).
Is the D²Pak drain tab electrically isolated?
No-the drain (tab) is directly connected to the silicon die's drain region and is not insulated. It must be mounted to a grounded or floating copper plane with appropriate creepage/clearance for system safety compliance. No isolation coating or thermal pad dielectric is included.
