Product details

Overview

IRFP4004PBF from Infineon Technologies (formerly International Rectifier) is a 40V, 195A (package-limited), N-channel enhancement-mode HEXFET Power MOSFET in TO-247AC package, optimized for high-efficiency synchronous rectification and hard-switched SMPS. It features 1.35mΩ typ. R_DS(on), 220nC total gate charge, and enhanced body diode dV/dt and dI/dt capability for robust unclamped inductive switching in UPS and telecom power systems.

For engineers reviewing the IRFP4004PBF datasheet, IRFP4004PBF pinout, IRFP4004PBF application, or IRFP4004PBF equivalent, key selection criteria include its 40V V_DSS, 195A continuous drain rating at T_C = 25°C, low 0.40°C/W R_θJC, avalanche-rated operation up to 1390mJ, and validated performance in high-frequency, high-current DC-DC stages.

Technical Context

This MOSFET employs planar silicon-gate technology with optimized cell pitch and trench-assisted body diode design to achieve ultra-low on-resistance while maintaining high dv/dt immunity (>2.5V/ns) and controlled reverse recovery (Q_rr = 190–290nC). Its SOA is fully characterized for linear-mode operation up to 10ms at 25°C case temperature.

The device integrates an intrinsic fast-recovery body diode with trr = 83–130ns and I_RRM ≤ 4.0A, enabling reliable synchronous rectification without external Schottky supplementation in 48V-input server PSUs and industrial motor drives.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage before avalanche onset; sets system bus voltage ceiling for 12V/24V/48V DC-DC stages.
R_DS(on) max	1.70mΩ - Ensures <1.7W conduction loss at 195A, critical for >98% efficiency in high-current output rails.
I_D (pkg-limited)	195A @ T_C = 25°C - Package thermal limit defines real-world current handling under forced-air heatsinking.
Q_g typ	220nC - Determines gate drive power requirement (~2.2mJ per switch cycle at 10V); impacts driver IC selection and layout parasitics.
E_AS	1390mJ - Single-pulse avalanche energy rating enables safe operation during inductive turn-off transients in UPS hold-up circuits.
R_θJC	0.40°C/W - Enables precise junction temperature prediction when mounted on greased heatsink; supports thermal derating to 139A at T_C = 100°C.
trr / Q_rr	83–130ns / 190–290nC - Low reverse recovery charge minimizes commutation losses and EMI in synchronous buck converters.

Pinout & Package

IRFP4004PBF uses the industry-standard TO-247AC package (3-lead, isolated tab), with drain connected to the metal tab for direct heatsink mounting. Pin assignment is fixed: Lead 1 = Gate, Lead 2 = Drain (tab), Lead 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Lead 1 (left)	Gate	High-impedance control terminal requiring ≥10V drive for full enhancement; sensitive to ESD (±20V max).
Lead 2 (center, tab)	Drain	Main high-side power terminal; electrically tied to heatsink; must be insulated if heatsink is grounded.
Lead 3 (right)	Source	Power return path and gate reference; connects to PCB ground plane; carries full load current and diode reverse recovery current.

Key Features

Feature	Design Value
Enhanced avalanche ruggedness	1390mJ single-pulse rating verified per JEDEC JESD24-11; supports unclamped inductive switching without snubbers.
Optimized body diode dI/dt capability	Rated for di/dt ≤ 690A/µs with ISD ≤ 195A - enables clean zero-voltage switching in LLC resonant converters.
Low C_oss eff. (TR)	3110pF - reduces turn-off energy loss and improves hard-switching efficiency above 200kHz.
Thermally robust SOA	DC-rated SOA up to 100A @ 20V with T_C = 25°C - supports linear-mode operation in hot-swap controllers and electronic fuses.
Improved dynamic dv/dt immunity	Tested >2.5V/ns - prevents false turn-on in high-noise motor drive half-bridges and PFC boost stages.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current 40V power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40V, 220A, R_DS(on) max = 1.45mΩ, TO-247 long leads; lower Q_g (180nC) but higher C_oss (3200pF).	Better gate drive efficiency but higher turn-off loss; requires tighter layout for dv/dt control.	Select when optimizing for gate drive power over switching frequency limits.
IXFH180N40X3	40V, 180A, R_DS(on) max = 1.55mΩ, HiPerFET Gen 3; 100% avalanche tested, lower trr (65ns), but higher cost.	Superior diode softness for EMI-sensitive medical equipment; limited to 180A package rating.	Select when reverse recovery noise or reliability under repetitive avalanche is critical.

Compared with STL220N4F7AG and IXFH180N40X3, IRFP4004PBF offers the highest package-limited current (195A) and best balance of R_DS(on), Q_g, and E_AS for cost-sensitive, high-power industrial SMPS where thermal margin and transient robustness are prioritized over ultra-high frequency operation.

FAQ

What is the maximum continuous drain current for IRFP4004PBF at 100°C case temperature?

The maximum continuous drain current at T_C = 100°C is 139A, derived from thermal derating of the 195A rating at 25°C using the 0.40°C/W R_θJC and 175°C maximum junction temperature. This value assumes proper heatsinking and is not silicon-limited - bond wire capacity remains the dominant constraint at lower temperatures.

Does IRFP4004PBF have a fully characterized avalanche SOA?

Yes - the datasheet provides Figures 12 and 14 showing maximum avalanche energy versus temperature and avalanche current versus pulse width, respectively. The device is rated for 1390mJ single-pulse avalanche energy with I_AS = 195A, V_GS = 10V, L = 15µH, and R_G = 25Ω, validated per JEDEC standards.

Can IRFP4004PBF be used in surface-mount designs?

No - the TO-247AC package is explicitly not recommended for surface-mount applications per the datasheet note on page 8. It requires through-hole mounting with mechanical screw attachment (6-32 or M3, 10 lb-in torque) to a heatsink for reliable thermal and electrical performance.

What is the typical reverse recovery charge (Q_rr) of the body diode?

The typical reverse recovery charge is 190nC at T_J = 25°C, rising to 210nC at T_J = 125°C, measured with I_F = 195A, dI/dt = 100A/µs, and V_R = 20V. This value is critical for calculating commutation losses in synchronous rectifier applications and is significantly lower than standard silicon diodes.
