Product details
Overview
IRFR9024NPBF from Infineon Technologies (formerly International Rectifier) is a P-channel enhancement-mode MOSFET in DPAK package, rated for -55 V VDSS, -11 A ID (TC = 25°C), RDS(on) ≤ 0.22 Ω at VGS = -10 V, and featuring fast body diode recovery (trr = 120 ns). It serves as a high-side load switch or reverse polarity protection device in DC power distribution circuits.
For engineers reviewing the IRFR9024NPBF datasheet, IRFR9024NPBF pinout, IRFR9024NPBF application, or IRFR9024NPBF equivalent, key selection criteria include verified RDS(on) at -10 V gate drive, guaranteed avalanche energy rating (EAS = 170 mJ), body diode forward voltage (VSD = 1.7 V @ IS = -5.5 A), and SOA compliance up to 100 µs pulse width.
Technical Context
This MOSFET employs planar stripe cell structure with optimized gate oxide thickness for stable threshold voltage (VGS(th) = -2.0 to -4.0 V) and low gate charge (Qg = 22 nC). Its rugged design supports repetitive avalanche operation without derating under controlled conditions.
The integrated body diode exhibits soft recovery characteristics (dv/dt < 5.5 V/ns) and low reverse recovery charge (Qrr = 42 nC), enabling use in synchronous rectification and bidirectional current paths where commutation stress must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -55 V - Maximum drain-source blocking voltage before avalanche onset |
| RDS(on) | ≤ 0.22 Ω @ VGS = -10 V - Ensures ≤1.3 W conduction loss at -5.5 A continuous drain current |
| ID (TC = 25°C) | -11 A - Continuous DC current capability with heatsink at case temperature ≤25°C |
| Qg | 22 nC - Total gate charge determining minimum driver peak current for 10–90% VGS transition |
| EAS | 170 mJ - Single-pulse avalanche energy rating at TJ = 25°C, enabling robustness against inductive switching transients |
| trr | 120 ns - Body diode reverse recovery time defining minimum dead-time in half-bridge topologies |
Pinout & Package
IRFR9024NPBF uses the DPAK (TO-252AA) surface-mount package with exposed drain pad for thermal dissipation. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control electrode | Receives negative voltage relative to source to turn on P-channel channel; requires ≥|2.0 V| threshold margin for reliable conduction |
| Drain (D) | High-side power node | Connected to input supply rail; tab is electrically tied to drain and serves as primary thermal path to PCB copper |
| Source (S) | Reference node | Bonded to PCB ground plane in high-side switch configuration; defines VGS reference for gate drive circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Lead-free (Pb-free) construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile for SnAgCu soldering |
| 100% UIS tested | Each unit validated for unclamped inductive switching stress up to rated EAS limit |
| Fast, soft-recovery body diode | Qrr = 42 nC and dv/dt < 5.5 V/ns reduce EMI and cross-conduction risk in bridge configurations |
| Enhanced SOA for linear mode | Rated for 100 µs pulse width at 25°C case temperature, supporting active current limiting applications |
Applications
| Reverse Polarity Protection | DC Motor Control |
|---|---|
Use Scenario: Input protection circuit for 24 V industrial PLC modules subjected to accidental battery reversal. IC Role / Device Role / Timing Role: P-channel MOSFET configured as high-side switch with gate driven by Zener-clamped resistor divider.

IC Role / Device Role / Timing Role: Low-loss replacement for Schottky diode in ideal diode configuration using external gate driver feedback. Use Value: RDS(on) ≤ 0.22 Ω cuts conduction loss by >60% versus 0.55 V Schottky, improving efficiency and reducing thermal footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLR9343PbF | RDS(on) = 0.18 Ω @ VGS = -10 V; lower Qg (18 nC); same DPAK package | Better efficiency at high-frequency PWM (>100 kHz) due to reduced gate drive loss | Select when optimizing for switching loss in compact DC-DC converters |
| STP12PF06 | RDS(on) = 0.28 Ω @ VGS = -10 V; higher VDSS (-60 V); TO-220 package | Requires through-hole mounting and larger heatsink; suited for higher-voltage industrial controls | Choose only if -60 V rating or through-hole assembly is mandatory |
Compared with IRFR9024NPBF, IRLL9343PbF offers lower conduction and switching losses in space-constrained SMT designs, while STP12PF06 trades package compatibility and RDS(on) for extended voltage margin and legacy board compatibility.

FAQ
What is the maximum allowable gate-source voltage for IRFR9024NPBF?
The absolute maximum VGS rating is ±20 V. Operation beyond ±12 V risks irreversible gate oxide damage. For reliable turn-on, apply -10 V to ensure RDS(on) remains ≤0.22 Ω across temperature and process variation; -4.5 V is sufficient for logic-level drive but increases RDS(on) to ~0.45 Ω.
Does IRFR9024NPBF require a gate resistor in high-side switch applications?
Yes - a gate resistor (typically 10–100 Ω) is required to dampen gate ringing caused by PCB trace inductance and MOSFET input capacitance. Without it, overshoot can exceed ±20 V, risking gate failure. Resistor value balances switching speed (lower R = faster) against EMI and shoot-through risk (higher R = slower, safer).
Can IRFR9024NPBF be used in linear (active) mode for current regulation?
Yes - its enhanced Safe Operating Area (SOA) supports linear operation up to 100 µs pulse width at TC = 25°C. For continuous DC regulation, derate power dissipation using the 1.1 W/°C thermal resistance (RθJC) and ensure case temperature stays below 100°C to avoid thermal runaway.
Is the drain tab of IRFR9024NPBF electrically isolated from other pins?
No - the exposed drain pad (Pin 2) is internally bonded to the drain terminal and is not insulated. It must be soldered to a PCB copper pour connected to the drain net. Any attempt to isolate it thermally or electrically violates the device's thermal design and may cause premature failure due to overheating.
