Product details

Overview

IRLP3034PBF from Infineon Technologies is a 40V, logic-level N-channel Power MOSFET in TO-247AC package, rated for 195A continuous drain current (package-limited) and 1.4mΩ typical R_DS(on) at V_GS = 10V. It delivers high-efficiency synchronous rectification in SMPS, hard-switched DC motor drives, and UPS systems where low conduction loss and robust avalanche capability are critical.

For engineers reviewing the IRLP3034PBF datasheet, IRLP3034PBF pinout, IRLP3034PBF application, or IRLP3034PBF equivalent, key selection criteria include its 1.6mΩ R_DS(on) at 4.5V gate drive, 108nC total gate charge, 39ns reverse recovery time, and validated unclamped inductive switching performance up to 1308A pulsed drain current.

Technical Context

This HEXFET® device uses planar stripe silicon technology optimized for low R_DS(on) × Q_g product at 4.5V drive, enabling efficient operation with standard logic-level controllers. Its body diode exhibits 1.3V forward voltage at 195A and 39ns trr at 25°C, supporting fast-recovery synchronous rectification.

The MOSFET features fully characterized avalanche SOA with 224mJ single-pulse E_AS, 4.6V/ns peak diode recovery dv/dt rating, and thermal resistance R_θJC = 0.44°C/W - enabling high-power density designs in forced-air or heatsink-mounted configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage for 12–24V bus applications including automotive and industrial SMPS.
R_DS(on) typ. @ 10V	1.4mΩ - Enables ≤2.8W conduction loss at 195A, critical for high-current synchronous rectifiers.
R_DS(on) max. @ 4.5V	2.0mΩ - Confirmed low on-resistance under logic-level gate drive, reducing driver complexity.
Q_g typ.	108nC - Defines gate drive energy requirement; supports 100kHz+ switching with moderate gate drivers.
trr	39ns - Fast body diode recovery minimizes shoot-through risk and commutation loss in half-bridge topologies.
E_AS	224mJ - Thermally limited single-pulse avalanche energy enables robustness against inductive load transients.
R_θJC	0.44°C/W - Allows 341W power dissipation at ΔT = 150°C, supporting high-current operation with direct heatsink mounting.

Pinout & Package

IRLP3034PBF uses the through-hole TO-247AC package with isolated tab (drain-connected), optimized for high-current PCB mounting and heatsink interface. Not recommended for surface-mount use.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Control terminal accepting 0–20V V_GS; 2.1Ω internal gate resistance limits ringing during fast switching.
D	Drain	Main high-side or low-side power path; electrically connected to metal tab for thermal and electrical conduction to heatsink.
S	Source	Power return node; referenced for gate drive; carries full load current and body diode reverse recovery current.

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Guaranteed turn-on with 4.5V V_GS, eliminating need for gate boosters in 5V/3.3V controller designs.
Enhanced body diode dV/dt and dI/dt capability	Rated for 4.6V/ns peak diode recovery dv/dt and >841A/µs di/dt, preventing false turn-on in hard-switched converters.
Fully characterized avalanche SOA	Validated 224mJ single-pulse E_AS and defined I_AR-t_av curves enable reliable unclamped inductive switching without derating.
Superior R×Q figure of merit at 4.5V	1.6mΩ × 108nC = 173Ω·nC - benchmark efficiency metric for high-frequency, high-current switch-mode applications.
Lead-free construction	RoHS-compliant materials and termination, qualified per JEDEC J-STD-020 reflow profile for lead-free assembly.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current logic-level N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFP4468PbF	Higher R_DS(on) (1.8mΩ @ 10V), higher Q_g (132nC), same TO-247AC package.	Lower switching efficiency at high frequency due to increased gate charge and conduction loss.	Preferred when cost sensitivity outweighs 12% higher conduction loss and 22% higher drive power demand.
STH315N10F7-6	100V rating, lower R_DS(on) (0.95mΩ @ 10V), but higher Q_g (165nC); TO-247-3L package with source-sense pin.	Over-spec'd voltage rating adds unnecessary cost and capacitance for 40V systems; sense pin requires layout changes.	Select only if future system voltage scaling to 60–80V is planned or if Kelvin-source layout is already implemented.

Compared with IRFP4468PbF and STH315N10F7-6, IRLP3034PBF offers optimal balance of 40V rating, sub-2mΩ on-resistance at logic-level drive, and industry-leading R×Q at 4.5V - making it the most efficient choice for 24–48V high-current SMPS and motor drive applications where thermal headroom is constrained.

FAQ

Is IRLP3034PBF suitable for surface-mount assembly?

No. The TO-247AC package is explicitly not recommended for surface-mount applications per Infineon's datasheet (Rev. 2.1, p.8). It requires through-hole mounting with mechanical screw attachment to a heatsink for thermal and electrical integrity. Reflow soldering is not supported.

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

At T_C = 100°C and V_GS = 10V, the silicon-limited continuous drain current is 232A. However, the package-limited rating remains 195A regardless of temperature, as bond wire current capacity does not improve with cooling.

Does IRLP3034PBF have avalanche-rated operation?

Yes. It is fully characterized for unclamped inductive switching with 224mJ single-pulse avalanche energy (E_AS) at T_J = 25°C. Repetitive avalanche is permitted only if junction temperature remains below 175°C and average power dissipation stays within thermal limits defined by Z_thJC.

How does the body diode performance compare to discrete Schottky rectifiers?

The body diode has V_SD = 1.3V at 195A and t_rr = 39ns - significantly faster than standard PN diodes but higher forward drop than 45V Schottky rectifiers (~0.55V). It is optimized for synchronous rectification where gate-controlled conduction dominates; standalone diode use is not recommended.
