IRFR2405TRPBF - 55V 56A N-Channel HEXFET MOSFET | Infineon
MPN: IRFR2405TRPBF ✓ Hoạt độngIRFR2405TRPBF Tóm tắt
A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled three-terminal switch used to switch and amplify signals in power-electronics circuits. As a member of the HEXFET family, this part uses Infineon's IR MOSFET process, a planar cell technology that combines low RDS(on) per silicon area with robust avalanche ruggedness. Within the broader taxonomy it sits under: N-Channel MOSFET -> Power MOSFET -> Discrete Semiconductor -> Power Management IC family. The DPAK (TO-252) surface-mount package enables compact PCB layouts while providing a large tab/drain thermal pad for heat extraction.
Key specifications include 55 V drain-source breakdown voltage (VDS), 56 A continuous ID at 25C case temperature, 110 W power dissipation (PD), 16 mOhm RDS(on) max at VGS=10V, 70 nC typical gate charge (Qg), and an operating junction temperature range of -55C to +175C. The device is also characterized by fast switching, logic-level gate drive support at VGS=10V, and 100% avalanche-tested ruggedness per industry standards.
The IRFR2405TRPBF uses Infineon's seventh-generation HEXFET process to achieve low on-resistance per unit silicon area while maintaining fast body-diode recovery and high dv/dt immunity. The advanced process technology reduces conduction losses substantially compared with earlier-generation 55V MOSFETs. Its drain tab doubles as the main thermal pathway, supporting sustained high-current operation with proper PCB copper heatsinking.
Typical applications include automotive and industrial power management (load switching, reverse-battery protection), motor control and DC motor drive circuits, synchronous rectifier stages in DC-DC buck/boost converters, solenoid and relay drivers, and high-current switching in power tool electronics. The 55 V rating also makes it useful in 12 V and 24 V bus systems where inductive transients occur.
When designing with this MOSFET, ensure the gate is driven with at least 10 V VGS to achieve full RDSon. Place a gate-source pull-down resistor (10-100 kOhm) to prevent accidental turn-on from high dV/dt transients. Provide adequate copper area on the drain tab for thermal dissipation - DPAK's thermal resistance depends directly on copper footprint size.

Ứng dụng tiêu biểu
IRFR2405TRPBF phù hợp cho 6 Áp dụngs: Automotive 12V/24V Load Switching, DC Motor Drive / H-Bridge Switch, Synchronous Rectifier in DC-DC Buck Converter, Reverse-Battery Protection Circuit, Solenoid and Relay Driver, Power Tool and Battery-Pack Switching.
Automotive 12V/24V Load Switching
The IRFR2405TRPBF's 55 V VDS, 56 A continuous ID, and 110 W power dissipation make it ideal for automotive 12V and 24V bus load-switching applications. With RDS(on) of 16 mOhm at VGS=10V, conduction losses are minimized across high-current loads such as headlamp drivers, fuel-pump controllers, and HVAC blower motors. The DPAK package with exposed drain tab provides a robust thermal path for sustained high-current operation in under-hood environments. Its 100% avalanche-tested ruggedness also tolerates the inductive kickback produced when switching solenoids, relays, and motors on the 12V/24V automotive bus.

DC Motor Drive / H-Bridge Switch
The IRFR2405TRPBF is well-suited as the low-side or high-side switch in DC motor H-bridge driver circuits driving brushed motors in robotics, power tools, and small EV traction. Its 56 A continuous rating handles stall-current surges typical of brushed DC motors, and its 70 nC total gate charge enables fast PWM switching above 20 kHz for smooth torque control. In H-bridge configurations, four IRFR2405TRPBF units form a complete bidirectional drive; the complementary P-channel variant IRFR5305TRPBF (also DPAK) can serve as the high-side switch with matched switching characteristics.

Synchronous Rectifier in DC-DC Buck Converter
The IRFR2405TRPBF can serve as the synchronous rectifier (low-side switch) in buck-converter designs for 12V-to-5V/3.3V step-down conversion. Its 16 mOhm RDS(on) at 10V gate drive minimizes rectifier conduction loss, which dominates total loss at high load currents. With 70 nC gate charge and fast body-diode recovery, it supports switching frequencies from 100 kHz to 500 kHz, enabling compact inductor-based designs. In high-current point-of-load converters for industrial and automotive ECUs, it efficiently replaces Schottky diodes and reduces rectifier losses by 50% or more.

Reverse-Battery Protection Circuit
The IRFR2405TRPBF is ideal as the high-side P-channel reverse-battery protection MOSFET replacement (using N-channel in high-side bootstrap configuration) or as the ground-side disconnect switch in automotive reverse-polarity protection modules. Its 55V VDS rating easily handles 24V jump-start transients on 12V systems, and the 16 mOhm RDS(on) keeps continuous current-path loss below 0.5W at 5A load. The TO-252AA (DPAK) package provides sufficient thermal dissipation for the moderate currents typical of body-control modules and ECU power inputs.

Solenoid and Relay Driver
The IRFR2405TRPBF handles the high inrush and inductive flyback energy when driving solenoids, relays, and valve actuators. With 56 A pulsed current capability and 100% avalanche energy rating, it absorbs the inductive kickback that occurs when the magnetic field collapses at switch-off, eliminating the need for external freewheeling diodes in many designs. Industrial solenoid-driver modules, fuel-injector drivers, and HVAC valve controls use this MOSFET to switch 1-5A continuous loads with fast PWM control and reliable avalanche absorption up to the part's 55V VDS ceiling.
Được đề xuất
Power Tool and Battery-Pack Switching
The IRFR2405TRPBF is widely used as the main power switch in cordless power tools and Li-ion battery-pack discharge protection circuits. Its 56 A continuous current handles the high discharge currents of 18V/20V cordless drill and impact-driver packs, while the 16 mOhm RDS(on) minimizes voltage drop across the discharge path to maximize runtime. The DPAK package's exposed thermal tab provides direct PCB heatsinking for the short-duration high-current pulses of cordless-tool motor starts and stall events. The TRPBF tape-and-reel format suits high-volume SMD production.

Ghi chú thiết kế
Estimated: at ID=20A with RDS(on)=16mOhm, conduction loss is roughly P=I^2*R=6.4W. DPAK's thermal resistance to a 1-square-inch copper pour on FR-4 is approximately 30-40 C/W, yielding a 192-256 C junction temperature rise above ambient - well above the 175C limit. To sustain 20A, use at least 4 square inches of drain-tab copper or add a small heatsink. For 5A applications, the same copper area keeps junction rise below 30C.
Solder the exposed drain tab directly to a continuous PCB copper pour. Use thermal vias (typically 0.3mm diameter, 0.5mm pitch) under the tab to conduct heat into inner copper layers. Place a 10kOhm gate-source resistor directly between gate and source pins to prevent parasitic turn-on from high dV/dt transients. Route the gate trace away from drain-source switching node to minimize capacitive coupling.
Do not drive the gate with less than 8V - the IRFR2405TRPBF is NOT a logic-level MOSFET and will not achieve full RDS(on) below VGS=10V. Do not exceed VGS=20V absolute maximum. Do not assume the 56A rating applies at PCB-mount - this rating requires Tc=25C (case temperature), and at TA=25C with no heatsink, derate to 15-20A maximum continuous. Do not skip the gate-source pull-down resistor or you may see sporadic turn-on from noise or ESD events.
Keep the gate-drive loop area as small as possible to minimize parasitic oscillation. Use a gate-drive resistor of 10-100 ohm in series with the gate to dampen ringing. Place input bulk capacitors close to the drain pin for switching applications. The source pin (pin 2) and source-sense connection (if used) should be Kelvin-connected to avoid adding source inductance to the gate-drive loop, which would slow switching and increase losses.
