Product details

Overview

IRLR024ZPBF from Infineon Technologies is a logic-level N-channel enhancement-mode Power MOSFET in D-Pak package, rated for 55V V_DSS, 58 mΩ R_DS(on) at V_GS = 10 V, and 16 A continuous drain current at T_C = 25°C. It features 175°C junction temperature rating, fast switching (t_r = 43 ns), and specified repetitive avalanche capability-designed for high-efficiency DC-DC converters, motor drives, and load-switching circuits.

For engineers reviewing the IRLR024ZPBF datasheet, IRLR024ZPBF pinout, IRLR024ZPBF application, or IRLR024ZPBF equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.0–3.0 V), low conduction loss at 5 V control, body diode recovery performance (t_rr = 16–24 ns), and thermal robustness under pulsed avalanche stress.

Technical Context

This HEXFET device uses advanced silicon processing to minimize R_DS(on) per die area while maintaining ruggedness. Its gate charge profile (Q_g = 6.6–9.9 nC, Q_gd = 3.9 nC) supports efficient high-frequency switching up to several hundred kHz in hard-switched topologies.

The integrated body diode exhibits low forward voltage (V_SD ≤ 1.3 V) and controlled reverse recovery (Q_rr = 11–17 nC), enabling reliable operation in synchronous rectification and freewheeling applications without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	55 V - maximum blocking voltage before avalanche onset; sets upper limit for bus voltage in buck, flyback, and half-bridge stages
R_DS(on)	58 mΩ @ V_GS = 10 V - defines conduction loss at full load; enables <1 W dissipation at 4 A continuous drain current
I_D (continuous)	16 A @ T_C = 25°C - thermal-limited current capacity with PCB heatsinking; derates to 11 A at 100°C case temperature
Q_g	6.6–9.9 nC - total gate charge determines driver strength requirement; compatible with standard logic-level gate drivers (e.g., TC442x)
t_r/t_f	43 ns / 16 ns - rise/fall times define minimum practical switching period; supports >500 kHz operation with appropriate gate resistance
T_J max	175°C - maximum junction temperature allows sustained operation in thermally constrained enclosures without forced cooling
E_AS	25 mJ (tested) - single-pulse avalanche energy rating validates unclamped inductive turn-off survivability in relay/motor drive snubberless designs

Pinout & Package

IRLR024ZPBF is housed in a surface-mount D-Pak (TO-252AA) package with exposed drain pad for thermal enhancement. The three terminals are arranged in standard S-D-G order (Source–Drain–Gate) when viewed from top with marking side up and leads pointing downward.

Pin/Terminal	Circuit Role	Design Meaning
Tab / Pin 2	Drain (D)	High-current output node; electrically connected to exposed copper pad-must be soldered to large PCB copper pour for thermal management
Pin 1	Source (S)	Power return path and gate reference; tied to ground or low-side switch node; carries full load current
Pin 3	Gate (G)	Control input; requires low-impedance drive due to 9.9 nC total charge; sensitive to ESD (±16 V absolute max gate voltage)

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V-enables direct interface with 3.3 V/5 V microcontrollers without level-shifting circuitry
Ultra-low R_DS(on)	58 mΩ at 10 V gate drive-reduces I²R losses by >30% vs. legacy 100 mΩ MOSFETs in 12 V input power stages
Repetitive avalanche rated	Specified for repeated unclamped inductive switching up to T_Jmax; eliminates need for external clamping diodes in solenoid and brushed motor drivers
175°C junction rating	Enables operation in sealed industrial enclosures or automotive under-hood environments where ambient exceeds 105°C
Lead-free construction	RoHS-compliant D-Pak package with matte tin plating-supports lead-free reflow profiles without whisker risk

Applications

DC-DC Buck Converter

Brushed DC Motor Driver

Use Scenario: Step-down regulator for FPGA core voltage (1.2 V @ 10 A) from 12 V rail in industrial PLC modules.

IC Role / Device Role / Timing Role: High-side synchronous rectifier MOSFET; switched at 300 kHz with 5 V gate drive from integrated controller.

Use Value: Low R_DS(on) minimizes conduction loss (<0.6 W), while fast t_r/t_f ensures clean PWM edges and reduced EMI generation.

Use Scenario: H-bridge driver for 24 V, 8 A brushed motor in automated gate actuator with stall detection.

IC Role / Device Role / Timing Role: Low-side switch in half-bridge configuration; commutated at <10 kHz with PWM duty cycling.

Use Value: Repetitive avalanche rating absorbs inductive kickback during rapid direction reversal without snubber components.

Hot-Swap Load Switch

LED Constant-Current Driver

Use Scenario: Inrush-limited 48 V backplane supply enable for modular telecom equipment.

IC Role / Device Role / Timing Role: Main pass transistor controlled by dedicated hot-swap controller (e.g., LTC4215); operates in linear region during soft-start.

Use Value: 175°C T_J rating prevents thermal shutdown during 500 ms inrush limiting phase with 15 A peak current.

Use Scenario: Dimmable constant-current driver for 36 V, 700 mA LED string in streetlight fixture.

IC Role / Device Role / Timing Role: Low-side current sink modulated via analog/PWM input; conducts continuously during ON phase.

Use Value: Tight V_GS(th) distribution (1.0–3.0 V) ensures consistent turn-on across temperature and unit-to-unit variation in open-loop dimming.

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	60 V V_DSS, 28 mΩ R_DS(on), 49 A I_D, TO-220 package	Higher current handling but larger footprint and higher gate charge (Q_g = 67 nC)	Preferred for higher-power linear or switching loads where thermal mass and heatsink mounting are available
SI2302DS-T1-GE3	20 V V_DSS, 55 mΩ R_DS(on), 3 A I_D, SOT-23 package	Lower voltage rating and current capacity; optimized for space-constrained low-voltage logic-level switching	Suitable for battery-powered IoT nodes or auxiliary bias rails where board area is critical and voltage stays below 16 V

Compared with IRLR024ZPBF, IRLZ44NPBF offers lower on-resistance and higher current but demands more gate drive energy and occupies greater PCB area; SI2302DS-T1-GE3 trades voltage headroom and thermal margin for ultra-compact size in sub-5 V systems.

FAQ

Is IRLR024ZPBF suitable for 3.3 V microcontroller gate drive?

Yes-its logic-level threshold (V_GS(th) = 1.0–3.0 V) and guaranteed R_DS(on) ≤ 80 mΩ at V_GS = 4.5 V make it fully compatible with 3.3 V GPIO outputs. For optimal efficiency, use a gate resistor ≤ 10 Ω and ensure driver peak current ≥ 200 mA to achieve t_r < 50 ns.

What is the maximum safe operating frequency for IRLR024ZPBF in a hard-switched buck converter?

With Q_g = 9.9 nC and typical gate driver capability (e.g., TC4427), the device supports reliable operation up to 1 MHz, though practical limits are set by switching loss (P_sw ≈ ½ × V_IN × I_OUT × (t_r + t_f) × f_SW). At 300 kHz and 12 V/5 A, switching loss remains <0.3 W with proper gate drive.

Does IRLR024ZPBF require a gate resistor for stability?

Yes-a series gate resistor (10–22 Ω) is recommended to dampen parasitic oscillation caused by trace inductance and Miller capacitance (C_rss = 39 pF). Omitting it risks shoot-through in bridge configurations and increased EMI due to ringing on V_GS and V_DS.

Can IRLR024ZPBF replace IRLU024ZPBF in existing designs?

Yes-IRLR024ZPBF (D-Pak) and IRLU024ZPBF (I-Pak) share identical electrical specifications and thermal ratings, differing only in package outline and thermal resistance (R_θJC = 4.28°C/W for both). PCB layout must accommodate D-Pak's wider lead spacing and larger exposed drain pad.
