Product details
Overview
IRFR9024NTRL from Infineon Technologies (formerly International Rectifier) is a P-channel enhancement-mode HEXFET® Power MOSFET in TO-252AA (D-Pak) surface-mount package, rated for -55 V V(BR)DSS, 0.175 Ω RDS(on) at VGS = -10 V and ID = -6.6 A, with fully avalanche-rated operation and fast switching (tr = 55 ns, tf = 37 ns). It serves as a high-efficiency low-side switch in DC-DC converters, motor control H-bridge legs, and load management circuits.
For engineers reviewing the IRFR9024NTRL datasheet, IRFR9024NTRL pinout, IRFR9024NTRL application, or IRFR9024NTRL equivalent, key selection criteria include its -55 V breakdown voltage, ultra-low on-resistance, -11 A continuous drain current at TC = 25°C, avalanche energy rating (EAS = 62 mJ), and D-Pak thermal performance (RθJC = 3.3 °C/W).
Technical Context
This device employs fifth-generation HEXFET process technology to achieve optimized conduction and switching trade-offs. Its P-channel architecture enables high-side or low-side configuration without level-shifting, and its integrated body diode supports synchronous rectification and freewheeling in inductive loads.
The TO-252AA package provides robust thermal coupling to PCB copper, enabling up to 38 W power dissipation at TC = 25°C with linear derating of 0.30 W/°C. Avalanche ruggedness is validated per unclamped inductive switching tests (IAS = -6.6 A, L = 2.8 mH, RG = 25 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -55 V - Maximum blocking voltage before avalanche onset; defines safe operating range in negative-rail switching applications. |
| RDS(on) | 0.175 Ω @ VGS = -10 V, ID = -6.6 A - Low conduction loss enabling <1.2 W I²R loss at 3 A continuous drain current. |
| ID (TC = 25°C) | -11 A - Continuous current capability with adequate heatsinking; usable up to -8 A at TC = 100°C. |
| EAS | 62 mJ - Single-pulse avalanche energy rating confirms robustness against inductive turn-off transients without external snubbers. |
| Qg / Qgd | 19 nC / 10 nC - Gate charge profile supports efficient 100–500 kHz PWM drive with moderate gate driver strength (e.g., 1–2 A peak). |
| RθJC | 3.3 °C/W - Junction-to-case thermal resistance enables direct thermal path to heatsink or copper pour, critical for sustained power handling. |
| tr / tf | 55 ns / 37 ns - Fast switching transitions reduce dynamic losses and EMI generation in high-frequency SMPS designs. |
Pinout & Package
IRFR9024NTRL uses the TO-252AA (D-Pak) surface-mount package with exposed drain pad for thermal and electrical connection. The package features three main terminals and an internal drain tie to pin 4, supporting high-current PCB routing and thermal dissipation via soldered copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Receives negative gate drive relative to source; threshold voltage -2.0 to -4.0 V enables compatibility with standard logic-level or dedicated gate drivers. |
| 2 (Drain) | Main power output | Connected internally to pin 4; electrically and thermally tied to exposed copper pad-must be routed to ground plane or heatsink for optimal thermal performance. |
| 3 (Source) | Reference node | Serves as return path for load current and gate drive reference; connects to system ground or negative rail depending on topology. |
| 4 (Drain) | Secondary drain connection | Redundant drain terminal reinforcing thermal and current-carrying capacity; must be soldered to same net as pin 2 and exposed pad. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 0.175 Ω enables <1.2 W conduction loss at 3 A, reducing thermal stress in compact power stages. |
| Fully avalanche-rated | 62 mJ single-pulse energy rating eliminates need for external clamping in inductive switching, simplifying layout and BOM. |
| Fast switching speed | 55 ns rise / 37 ns fall times support >300 kHz operation while maintaining low dynamic loss and EMI. |
| D-Pak surface-mount package | TO-252AA footprint allows automated assembly and direct thermal coupling to PCB copper, achieving 3.3 °C/W junction-to-case resistance. |
| P-channel topology | Enables high-side switching without bootstrap circuitry or level shifters in negative-rail systems such as automotive battery disconnects. |
Applications
| Automotive Load Switch | DC-DC Synchronous Rectifier |
|---|---|
Use Scenario: Controlling 12 V battery-fed accessories (e.g., HVAC actuators, lighting modules) with overcurrent and short-circuit protection. IC Role / Device Role / Timing Role: Low-side P-channel MOSFET used as protected load switch, driven by microcontroller GPIO with active-low logic. Use Value: -55 V rating withstands load-dump transients; RDS(on) ≤ 0.175 Ω limits self-heating during 5 A steady-state operation. | Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 3.3–12 V at up to 5 A. IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode to reduce conduction loss and improve efficiency above 300 kHz. Use Value: Body diode VSD = -1.6 V at -7.2 A enables low-loss freewheeling; fast trr = 47–71 ns minimizes reverse recovery loss. |
| H-Bridge Motor Driver | Industrial Power Sequencing |
Use Scenario: Bidirectional 24 V brushed DC motor control in factory automation actuators requiring regenerative braking. IC Role / Device Role / Timing Role: P-channel MOSFET in high-side leg of half-bridge; paired with N-channel low-side for complementary drive. Use Value: Avalanche rating handles back-EMF spikes during abrupt stop; Qgd = 10 nC ensures clean commutation with minimal shoot-through risk. | Use Scenario: Controlled power-up sequencing of FPGA, DSP, or multi-rail ASIC supplies in programmable logic controllers. IC Role / Device Role / Timing Role: Delayed enable switch isolating downstream rails until primary supply stabilizes and supervisor signals OK. Use Value: -11 A ID rating supports inrush current of large bulk capacitors; PD = 38 W allows brief surge handling without thermal shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFR9120TRLPBF | V(BR)DSS = -100 V, RDS(on) = 0.27 Ω @ -10 V - higher voltage rating but 54% higher on-resistance. | Better suited for 48 V industrial bus systems; less efficient at 12–24 V due to higher conduction loss. | Select when system requires >60 V transient immunity and can tolerate ~1.5× higher I²R loss at 5 A. |
| DMG2305UVT-7 | V(BR)DSS = -20 V, RDS(on) = 0.045 Ω @ -4.5 V - logic-level compatible, lower voltage, much lower on-resistance. | Optimized for 3.3–5 V logic-driven loads (e.g., USB-C PD, portable devices); not suitable for 12 V+ systems. | Choose for space-constrained, low-voltage, high-efficiency applications where gate drive is limited to 3.3–4.5 V. |
Compared with IRFR9024NTRL, IRFR9120TRLPBF trades conduction efficiency for higher voltage margin, while DMG2305UVT-7 sacrifices voltage headroom for ultra-low RDS(on) and logic-level drive-making IRFR9024NTRL the balanced choice for 12–24 V industrial and automotive switching where both ruggedness and efficiency matter.

FAQ
Is IRFR9024NTRL suitable for high-side switching in a 24 V system?
Yes. As a P-channel MOSFET with -55 V V(BR)DSS and -11 A continuous drain rating, it supports high-side switching in 24 V nominal systems-including automotive 12 V and industrial 24 V rails-with margin for load dump (up to ±40 V transients). Gate drive must be referenced to source and pulled negative relative to it.
What is the maximum recommended PCB copper area for thermal performance?
Per AN-994, a 1" square (25.4 mm × 25.4 mm) FR-4 PCB copper area under the exposed drain pad achieves RθJA ≈ 50 °C/W. For improved cooling, use ≥2 oz copper, thermal vias (≥8 × 0.3 mm) to inner ground planes, and minimize trace length between pins 2/4 and the pad-enabling sustained 38 W dissipation at TC = 25°C.
Does IRFR9024NTRL require a gate resistor for stability?
A gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by gate loop inductance and Miller capacitance (Crss = 92 pF). Without it, fast edges may excite parasitic oscillations, increasing EMI and risking false turn-on. The resistor value balances switching speed (tr/tf) and noise immunity per your driver's peak current capability.
Can IRFR9024NTRL replace IRF9Z24N in existing designs?
Yes-IRFR9024NTRL is a direct surface-mount replacement for through-hole IRF9Z24N (same die, TO-252AA vs. TO-220AB), sharing identical electrical specs including RDS(on), V(BR)DSS, and avalanche ratings. Layout changes are required for mounting and thermal relief, but no circuit redesign is needed for functionally equivalent operation.
