Product details

Overview

IRLSL3034PBF from Infineon Technologies is a logic-level N-channel Power MOSFET in D2PAK (TO-262) package, designed for high-current switching in DC motor drives and synchronous rectification. It delivers 40 V V_DS, 1.4 mΩ R_DS(on) at 4.5 V V_GS, 195 A package-limited continuous drain current, and enhanced body diode dV/dt/dI/dt capability - enabling robust operation in hard-switched SMPS and UPS systems.

For engineers reviewing the IRLSL3034PBF datasheet, IRLSL3034PBF pinout, IRLSL3034PBF application, or IRLSL3034PBF equivalent, key selection criteria include its 1.4 mΩ on-resistance at 4.5 V gate drive, 108 nC total gate charge, 195 A pulsed source current rating, avalanche energy of 255 mJ, and SOA compliance up to 10 ms at 100 A/40 V.

Technical Context

This MOSFET uses planar HEXFET architecture with optimized trench-assisted gate structure to achieve ultra-low R_DS(on) while maintaining fast switching and rugged unclamped inductive switching (UIS) performance. Its gate threshold voltage (1.0–2.5 V) ensures reliable turn-on with standard logic-level drivers.

The device integrates a co-packaged, enhanced body diode with 39 ns reverse recovery time (T_J = 25°C) and 39 nC Q_rr, supporting high-frequency synchronous rectification without external Schottky supplementation. Thermal resistance R_θJC is 0.4 °C/W, enabling high-power density PCB mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage for 12–24 V bus applications with 20 % margin
R_DS(on) @ 4.5 V	1.4 mΩ typ. - Enables ≤1.2 W conduction loss at 195 A, critical for thermal management in compact UPS modules
I_D (Package)	195 A @ T_C = 25°C - Determined by bond wire and leadframe limits, not silicon capacity
Q_g	108 nC max. - Dictates gate driver power requirement; supports 100 kHz+ switching with <1 W driver dissipation
E_AS	255 mJ - Single-pulse avalanche energy at T_J = 25°C, enabling reliable operation under inductive load transients
trr / Q_rr	39 ns / 39 nC - Fast, low-charge body diode recovery reduces cross-conduction losses in synchronous buck converters
R_θJC	0.4 °C/W - Allows direct heatsink mounting; 100 W power dissipation raises junction only 40°C above case

Pinout & Package

IRLSL3034PBF is housed in a surface-mount D2PAK (TO-262) package with exposed drain pad for thermal and electrical connection. The three terminals are arranged in standard G-D-S order (Gate–Drain–Source) on the lead frame.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Accepts 4.5–20 V logic-level drive; 2.1 Ω internal gate resistance dampens ringing
Drain (D)	Main current sink	Connected to exposed copper pad; carries full load current and serves as primary thermal path to heatsink
Source (S)	Current return/reference node	Low-inductance connection point for sense resistor placement and gate driver ground referencing

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Guaranteed turn-on at 4.5 V V_GS; eliminates need for gate boosters in 5 V microcontroller-based motor controllers
Enhanced body diode ruggedness	Rated for 841 A/µs dI/dt and high dV/dt; sustains repetitive UIS events without parameter shift
Optimized R×Q_g product	1.4 mΩ × 108 nC = 151 mΩ·nC - Balances conduction and switching loss for 50–200 kHz SMPS topologies
Lead-free and RoHS-compliant	Meets JEDEC J-STD-020 reflow profile; compatible with standard Pb-free assembly processes
Characterized SOA and avalanche curves	Full Safe Operating Area defined up to 10 ms pulse width; enables confident design without derating guesswork

Applications

IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode; driven complementary to primary-side MOSFET.

Use Value: 39 ns trr and 39 nC Q_rr cut reverse recovery loss by >70 % versus discrete SiC Schottky + driver solution.

Uninterruptible Power Supply

Use Value: C_{oss eff}(TR) = 2986 pF ensures predictable turn-off timing and minimal capacitive loss during hard commutation.

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
IRFB3004PBF	Higher R_DS(on) (1.6 mΩ), same 40 V rating, TO-220 package, no enhanced diode	Limited to lower-frequency (<50 kHz) motor drives due to slower trr (65 ns) and higher Q_rr (62 nC)	Prefer when cost sensitivity outweighs efficiency needs and TO-220 mechanical fit is required
STL220N4F7AG	40 V, 1.3 mΩ R_DS(on), 220 A rating, but 135 nC Q_g and no published E_AS data	Not recommended for avalanche-prone UPS inverters; better suited for low-dV/dt DC-DC converters	Choose only if gate drive capability exceeds 2 W and avalanche robustness is not required

Compared with IRLSL3034PBF, IRFB3004PBF trades 14 % higher conduction loss for lower gate drive demand and simpler thermal mounting, while STL220N4F7AG offers marginally lower R_DS(on) but lacks validated UIS performance and increases driver sizing burden.

FAQ

Is IRLSL3034PBF suitable for 5 V microcontroller gate drive?

Yes. With a gate threshold voltage range of 1.0–2.5 V and guaranteed R_DS(on) at 4.5 V V_GS, it fully turns on using standard 5 V GPIO outputs. No level-shifting or gate boosting circuitry is required, simplifying PCB layout and reducing BOM count in motor control designs.

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

At T_C = 100°C, the continuous drain current is derated to 243 A (silicon-limited) per the datasheet's Fig. 9. However, the package-limited rating remains 195 A regardless of temperature - this is the practical upper limit for sustained operation with standard D2PAK thermal pads and 1 oz copper.

Does IRLSL3034PBF have a specified body diode reverse recovery charge (Q_rr)?

Yes. Q_rr is specified as 39 nC at T_J = 25°C and 46 nC at T_J = 125°C, measured with I_F = 195 A, dI/dt = 100 A/µs, and V_R = 34 V. This value is critical for calculating synchronous rectifier switching loss in high-frequency DC-DC converters.

Can IRLSL3034PBF be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (see Fig. 4) ensures inherent current sharing. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and shared heatsinking. Derate total current by 15 % for two devices and 25 % for three or more to account for thermal coupling and layout asymmetry.
