Product details

Overview

IRL1404PBF from Infineon Technologies (formerly International Rectifier) is a 40 V, 160 A N-channel enhancement-mode power MOSFET in TO-220AB package, featuring 4.0 mΩ R_DS(on) at V_GS = 10 V, 140 nC total gate charge, and full avalanche rating-designed for high-current DC-DC converters, motor drives, and industrial power switching where low conduction loss and robust unclamped inductive switching are critical.

For engineers reviewing the IRL1404PBF datasheet, IRL1404PBF pinout, IRL1404PBF application, or IRL1404PBF equivalent, key selection criteria include its 4.0 mΩ on-resistance at 10 V gate drive, 640 A pulsed drain current capability, 620 mJ single-pulse avalanche energy, TO-220AB thermal resistance (R_θJC = 0.75 °C/W), and body diode recovery time (t_rr = 63–94 ns).

Technical Context

This HEXFET® Seventh Generation device uses advanced silicon processing to minimize R_DS(on) per die area while maintaining ruggedness against repetitive and single-pulse avalanche stress. Its gate threshold voltage (1.0–3.0 V) enables direct logic-level drive compatibility with 4.3 V and higher controllers.

The MOSFET integrates a fast, low-V_SD (1.3 V @ 95 A) intrinsic body diode with controlled reverse recovery (Q_rr = 170–250 nC, t_rr = 63–94 ns), supporting synchronous rectification and freewheeling in hard-switched topologies without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage before avalanche onset; sets upper limit for bus voltage in 12–24 V systems.
R_DS(on)	4.0 mΩ @ V_GS = 10 V - Enables ≤6.4 W conduction loss at 40 A continuous, reducing heatsink requirements.
I_D (25°C)	160 A - Continuous drain current rating at case temperature 25°C; derates linearly above 25°C (1.3 W/°C).
E_AS	620 mJ - Single-pulse avalanche energy capacity; supports reliable operation under unclamped inductive turn-off transients.
Q_g	140 nC - Total gate charge determines driver strength requirement; ~1.4 A peak needed for 100 ns switching at 10 V swing.
t_rr	63–94 ns - Body diode reverse recovery time; impacts switching loss and EMI in hard-commutated circuits.
R_θJC	0.75 °C/W - Junction-to-case thermal resistance; allows ~150°C junction rise at 200 W dissipation with ideal heatsinking.

Pinout & Package

IRL1404PBF is housed in a TO-220AB package with isolated tab (drain-connected), standard lead spacing, and screw-mount capability (10 lbf·in torque). The package provides low thermal resistance and mechanical robustness for industrial power modules and board-mounted regulators.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heat sink interface	Electrically connected to metal tab; must be electrically isolated from chassis unless system design permits common-drain configuration.
Source	Reference node for gate control / return path for load current	Low-inductance source connection critical for minimizing shoot-through risk and gate oscillation during high-di/dt switching.
Gate	Control terminal for channel modulation	High-impedance input requiring <200 nA leakage handling; sensitive to ESD and requires gate resistor (typically 2.5 Ω) for damping.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	4.0 mΩ at 10 V gate drive reduces conduction losses by >30% vs. prior-generation 40 V MOSFETs in 48 V input DC-DC stages.
Full avalanche rating	Rated for 620 mJ single-pulse and 20 mJ repetitive avalanche energy-enables elimination of snubbers in relay drivers and solenoid controls.
Logic-level gate drive	V_GS(th) = 1.0–3.0 V ensures reliable turn-on with 3.3 V or 5 V microcontrollers without level-shifting circuitry.
Fast body diode	t_rr = 63–94 ns and Q_rr = 170–250 nC support efficient freewheeling in half-bridge motor drives without external Schottky supplementation.

Applications

DC-DC Converter Primary Switch

Brushed DC Motor H-Bridge High-Side

Use Scenario: 12–24 V input, 300 kHz synchronous buck converter delivering up to 80 A to FPGA or ASIC core rails.

IC Role / Device Role / Timing Role: Main high-side switching element handling continuous 160 A peak currents with minimal R_DS(on)-dominated loss.

Use Value: 4.0 mΩ on-resistance limits conduction loss to <10 W at 80 A, enabling compact heatsink design and >95% efficiency at full load.

Use Scenario: 24 V brushed motor drive with PWM frequency up to 20 kHz, requiring bidirectional current control and regenerative braking.

IC Role / Device Role / Timing Role: High-side switch in H-bridge topology; conducts forward current and blocks reverse flyback during active braking.

Use Value: 640 A pulsed drain rating and 620 mJ avalanche energy tolerate motor inductance kickback without clamping components.

Industrial Power Supply OR-ing FET

Hot-Swap Controller Back-End Switch

Use Scenario: Redundant 48 V telecom power shelf using N+1 architecture with automatic load sharing between parallel PSUs.

IC Role / Device Role / Timing Role: Low-loss OR-ing switch placed between PSU output and common bus; conducts only when upstream voltage exceeds bus voltage.

Use Value: 1.3 V body diode forward drop and 4.0 mΩ R_DS(on) reduce insertion loss to <0.5% at 100 A, improving system efficiency over discrete diode solutions.

Use Scenario: 12 V hot-swap module protecting backplane from inrush and short-circuit faults during card insertion.

IC Role / Device Role / Timing Role: Main pass transistor controlled by dedicated hot-swap IC; ramps gate voltage to limit inrush dv/dt and withstand 100 A fault currents.

Use Value: 175°C max junction temperature and 0.75 °C/W R_θJC allow sustained 100 A operation with active thermal monitoring and foldback protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 40 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF1404PBF	R_DS(on) = 4.7 mΩ (higher), Q_g = 131 nC (lower), same TO-220AB package	Slightly lower switching loss but higher conduction loss; less suitable for high-current continuous duty	Select when gate drive strength is limited and peak current <120 A.
STP160NF04Z	R_DS(on) = 3.8 mΩ, Q_g = 150 nC, same V_DSS, different pinout (TO-220FP variant)	Lower on-resistance improves efficiency at high load; higher Q_g increases driver demand	Prefer for new designs targeting <3.8 mΩ R_DS(on) where gate drive can support 150 nC.

Compared with IRL1404PBF, IRF1404PBF trades 0.7 mΩ higher on-resistance for 9 nC lower gate charge-favoring drive-limited systems-while STP160NF04Z offers marginally better conduction efficiency at the cost of increased gate drive burden and non-drop-in pinout.

FAQ

Is IRL1404PBF suitable for 3.3 V microcontroller gate drive?

Yes. With a gate threshold voltage range of 1.0–3.0 V and guaranteed turn-on at V_GS = 4.3 V (ID = 40 A), the IRL1404PBF achieves usable R_DS(on) with 3.3 V logic outputs when paired with appropriate gate resistors and layout practices to minimize Miller-induced shoot-through.

What is the maximum recommended continuous current at 100°C case temperature?

At T_C = 100°C, the continuous drain current is rated at 110 A per the Absolute Maximum Ratings table. This reflects thermal derating from the 160 A rating at 25°C, based on the device's 1.3 W/°C linear derating factor and 200 W maximum power dissipation limit.

Does IRL1404PBF have a built-in ESD protection diode on the gate?

No. The IRL1404PBF does not integrate gate ESD protection; its gate oxide is rated for ±20 V absolute maximum V_GS. External gate protection (e.g., 12 V Zener clamp to source) is required in environments with handling or system-level ESD exposure.

Can IRL1404PBF replace IRF1404PBF in an existing PCB layout?

Yes-both share identical TO-220AB package dimensions, pinout (D-S-G), and mounting hole pattern. However, the IRL1404PBF's lower R_DS(on) (4.0 vs. 4.7 mΩ) and higher Q_g (140 vs. 131 nC) may require verification of gate drive capability and thermal margin in high-frequency, high-duty-cycle applications.
