Product details

Overview

IRF2804SPBF from Infineon Technologies (formerly International Rectifier) is a 40V, 75A N-channel D2Pak-7L Power MOSFET with 1.5mΩ typical R_DS(on) at V_GS = 10V, 175°C maximum junction temperature, and 160nC total gate charge - optimized for high-current DC-DC converters, motor drives, and synchronous rectification in industrial power supplies.

For engineers reviewing the IRF2804SPBF datasheet, IRF2804SPBF pinout, IRF2804SPBF application, or IRF2804SPBF equivalent, key selection criteria include its ultra-low on-resistance, fast switching (13ns turn-on delay, 120ns rise time), repetitive avalanche rating up to T_jmax, and D2Pak thermal performance (R_θJC = 0.50°C/W).

Technical Context

This HEXFET® device uses advanced silicon processing to achieve 1.5mΩ R_DS(on) at 75A/10V, enabling high-efficiency operation in high-current, low-voltage power stages. Its 175°C rated junction temperature supports sustained conduction under thermally constrained conditions.

The MOSFET integrates a robust body diode with 56–84ns reverse recovery time and 67–100nC Q_rr, supporting synchronous rectification and unclamped inductive switching. Gate drive requirements are defined by 160nC total charge and 41nC gate-to-source charge, compatible with standard 12V gate drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum drain-source blocking voltage; suitable for 12V/24V bus systems with margin against transients.
R_DS(on) typ.	1.5mΩ @ V_GS = 10V, I_D = 75A - Enables <1W conduction loss at 75A, critical for high-efficiency power stages.
I_D cont.	75A @ T_C = 25°C - Continuous current capability limited by package thermal resistance (0.50°C/W).
Q_g	160nC - Total gate charge determines driver power and switching loss; requires ≥1A peak gate drive for fast transitions.
t_r/t_f	120ns/130ns - Fast edge rates reduce switching losses in hard-switched topologies operating up to ~200kHz.
E_AS	540mJ - Single-pulse avalanche energy rating allows safe operation during inductive fault events without clamping circuitry.
T_J max	175°C - High junction temperature rating enables reliable operation in compact heatsink designs or elevated ambient environments.

Pinout & Package

IRF2804SPBF is housed in a surface-mount D2Pak-7L (TO-263-7L) package with isolated tab, optimized for PCB thermal conduction and high-current routing. The package features a copper leadframe and enhanced thermal interface for low R_θJC.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; accepts 10V logic-level drive; 41nC Qgs ensures predictable Miller effect timing.
2 (S)	Source	Power return path; internal source inductance (7.5nH) impacts high-di/dt switching stability.
3 (D)	Drain	Main power output; connected to die backside via exposed tab; electrically tied to tab in D2Pak-7L.
4–7 (D)	Drain (parallel)	Four additional drain terminals reduce package inductance and improve current sharing; lowers effective L_D to 4.5nH.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	1.5mΩ typ. at 75A - Reduces I²R losses by >30% vs. legacy 3.0mΩ devices in 12V battery-powered systems.
Repetitive avalanche rating	Rated for repeated unclamped inductive switching up to T_jmax - eliminates need for external snubbers in motor gate-drive circuits.
High-temperature operation	175°C T_J max with full R_DS(on) spec - maintains performance in sealed enclosures or high-ambient industrial environments.
Low gate charge	160nC Q_g with 66nC Q_gd - minimizes Miller-induced shoot-through risk and enables clean 100kHz+ PWM control.

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
STL220N4F7AG	R_DS(on) = 1.4mΩ @ 75A, V_GS = 10V; DFN8 5x6 package; no integrated avalanche rating.	Requires external avalanche protection in inductive loads; better suited for space-constrained DC-DC, not motor drives.	Select when PCB area is critical and avalanche stress is absent; verify gate drive compatibility with lower Q_g (135nC).
IXFH75N30P3	V_DSS = 300V; R_DS(on) = 12mΩ @ 75A; TO-247 package; higher R_θJC (0.45°C/W).	Designed for 200–400V bus systems; unsuitable for 40V applications due to excessive on-resistance penalty.	Only consider if system requires higher breakdown voltage; avoid for 40V designs due to 6× higher conduction loss.

Compared with STL220N4F7AG and IXFH75N30P3, IRF2804SPBF uniquely balances ultra-low R_DS(on), rated repetitive avalanche, and D2Pak thermal performance - making it optimal for 40V industrial motor drives and high-current synchronous rectifiers where reliability under transient stress is mandatory.

FAQ

What is the maximum continuous drain current for IRF2804SPBF at 100°C case temperature?

At T_C = 100°C, the continuous drain current is 190A per the absolute maximum ratings table - but this is silicon-limited and assumes ideal thermal management. In practice, the package-limited current at 100°C is 108A, governed by R_θJC = 0.50°C/W and P_D derating. Real-world design must respect both limits and verify junction temperature using Z_thJC curves.

Does IRF2804SPBF support logic-level gate drive?

No - IRF2804SPBF has a gate threshold voltage range of 2.0–4.0V but is specified for full enhancement at V_GS = 10V. Its R_DS(on) is guaranteed only at 10V, and drive below 8V results in significantly higher on-resistance (e.g., ~4.5mΩ at 5V). It requires a dedicated 10V gate driver, not 3.3V or 5V logic outputs.

How does the D2Pak-7L package improve thermal performance over standard D2Pak?

The D2Pak-7L adds four extra drain terminals (pins 4–7) that parallel the main drain connection, reducing package inductance (L_D = 4.5nH vs. 8.5nH in standard D2Pak) and spreading current across more copper. This improves thermal coupling to the PCB and lowers effective R_θJA by ~15% in FR-4 layouts, enabling higher sustained current without exceeding T_jmax.

Can IRF2804SPBF be used in parallel configurations?

Yes - its positive R_DS(on) temperature coefficient (normalized R_DS(on) rises with temperature) enables inherent current sharing. However, layout symmetry is critical: matched gate trace lengths, Kelvin source connections, and identical thermal paths are required. Derate total current by 15% for two devices and 25% for three or more to account for parametric spread and thermal coupling.
