Product details

Overview

IRF2804LPBF from Infineon Technologies (formerly International Rectifier) is a 40V, 75A N-channel D2Pak-7L Power MOSFET with 2.0mΩ R_DS(on) at V_GS = 10V, 175°C junction rating, and rated repetitive avalanche energy of 1160mJ - designed for high-current DC-DC converter primary-side switching in industrial power supplies.

For engineers reviewing the IRF2804LPBF datasheet, IRF2804LPBF pinout, IRF2804LPBF application, or IRF2804LPBF equivalent, key selection criteria include its ultra-low on-resistance, fast switching (t_r = 120ns), 175°C thermal capability, and D2Pak-7L package compatibility with high-power PCB layouts requiring low-inductance source connections.

Technical Context

This HEXFET® device uses advanced silicon processing to achieve 1.5mΩ typical R_DS(on) at 25°C and maintains stable conduction up to 175°C junction temperature. Its gate charge profile (Q_g = 160–240nC) supports efficient hard-switching in synchronous buck and full-bridge topologies.

The integrated body diode exhibits 1.3V forward voltage at 75A and 56–84ns reverse recovery time, enabling robust operation in freewheeling paths. Repetitive avalanche capability is validated per Fig. 12a/12b with I_AS = 75A, L = 0.24mH, and R_G = 25Ω under T_J ≤ 175°C constraints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage for 12V/24V input bus applications without derating
R_DS(on) max	2.0mΩ @ V_GS = 10V - Enables <1W conduction loss at 75A continuous current
I_D cont	75A @ T_C = 25°C - Sustains full-rated load in forced-air-cooled industrial SMPS
E_AS	540mJ (tested), 1160mJ (repetitive) - Supports unclamped inductive turn-off in motor drive H-bridges
Q_g	160–240nC - Determines gate driver current requirement (~2.4A peak for 100ns rise time)
R_θJC	0.50°C/W - Enables 150W dissipation with 75°C case-to-sink ΔT using greased interface
t_r/t_f	120ns/130ns - Limits switching losses to <1.2mJ per 100kHz cycle at 75A/20V

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	R_DS(on) = 1.8mΩ (typ), Q_g = 180nC, DFN8 5x6 package	No exposed drain pad; limited to 60A continuous due to package thermal resistance	Select for space-constrained designs where 75A rating is not required and surface-mount assembly is preferred
IXFH42N40P	R_DS(on) = 2.4mΩ, TO-247 package, 150°C T_J max	Larger footprint; higher R_θJC (0.4°C/W) but superior avalanche ruggedness (E_AS = 1500mJ)	Select when higher single-pulse avalanche immunity is critical and board area permits TO-247 mounting

Compared with STL220N4F7AG and IXFH42N40P, IRF2804LPBF uniquely balances ultra-low on-resistance, D2Pak-7L thermal performance, and validated repetitive avalanche behavior - making it optimal for high-reliability 75A industrial switching where thermal density and fault tolerance are co-constrained.

FAQ

What is the maximum continuous drain current for IRF2804LPBF at 100°C case temperature?

The maximum continuous drain current is 190A at T_C = 25°C and derates to 108A at T_C = 100°C per Figure 9 in the datasheet. This value is silicon-limited and assumes V_GS = 10V, with thermal design ensuring T_J ≤ 175°C.

Does IRF2804LPBF support Kelvin source sensing, and how is it implemented?

Yes - the D2Pak-7L package provides a dedicated Kelvin source pin (Pin 2) electrically isolated from the main source path (Pin 3). This enables precise current measurement by routing sense traces directly to the die bond wire, eliminating PCB trace resistance error in high-accuracy protection circuits.

What is the recommended gate resistor value for hard-switching applications at 100kHz?

A 5.1Ω gate resistor is recommended for 100kHz operation with 12V gate drive, achieving ~100ns rise time while limiting peak gate current to ~2.35A. This value balances switching loss reduction against ringing suppression, as confirmed by gate charge curves in Figure 6 and layout guidelines in AN-994.

How does the repetitive avalanche rating of IRF2804LPBF compare to single-pulse testing?

The tested single-pulse avalanche energy is 540mJ, while the repetitive rating is 1160mJ under conditions defined in Figures 12a/12b: I_AS = 75A, L = 0.24mH, R_G = 25Ω, and duty cycle ≤ 2%. Repetitive operation is thermally limited and requires strict adherence to Z_thJC transient curves in Figure 11 to avoid cumulative junction overheating.
