Product details

Overview

IRLSL4030PBF from Infineon Technologies is a 100V, 180A N-channel logic-level power MOSFET in D²PAK (TO-263) package, optimized for 4.5V gate drive, featuring 3.4mΩ typ. R_DS(on), 87nC total gate charge, and enhanced body diode dI/dt capability. It serves as a high-current synchronous rectifier or hard-switched main switch in DC motor drives and UPS systems.

For engineers reviewing the IRLSL4030PBF datasheet, IRLSL4030PBF pinout, IRLSL4030PBF application, or IRLSL4030PBF equivalent, key selection criteria include its low 4.5V-threshold on-resistance, avalanche-rated energy handling (730mJ), SOA-limited switching robustness, and D²PAK thermal performance under high-current pulsed loads.

Technical Context

This MOSFET employs planar stripe HEXFET architecture with optimized cell pitch and trench-assisted body diode design to achieve superior R×Q product at 4.5V V_GS. Its gate structure reduces Miller charge (Q_gd = 45nC) and improves dV/dt immunity during commutation.

The device integrates a fully characterized intrinsic p-n junction body diode rated for 110A pulsed source current and 50ns reverse recovery time at 25°C. Thermal design relies on low R_θJC = 0.40°C/W and validated SOA curves up to 10ms pulses at 100V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100V - Maximum blocking voltage before avalanche onset; defines safe operating range in 48V–72V bus applications.
R_DS(on) typ.	3.4mΩ @ V_GS = 4.5V - Enables <1.5W conduction loss at 92A DC, critical for high-efficiency synchronous rectification.
I_D cont.	180A @ T_C = 25°C - Supports high-current motor phase legs without parallel devices in industrial inverters.
Q_g	87nC - Determines gate driver power requirement; compatible with standard 1A peak drivers at ≤100kHz switching.
E_AS	730mJ - Specifies single-pulse unclamped inductive switching capability; validates ruggedness in relay/snubberless designs.
trr	50ns @ T_J = 25°C - Limits reverse recovery losses in high-frequency SMPS; enables >200kHz operation with controlled di/dt.
R_θJC	0.40°C/W - Enables direct heatsink mounting with minimal thermal interface resistance; supports >150W continuous dissipation.

Pinout & Package

IRLSL4030PBF uses the D²PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection. The three terminals are arranged in G–D–S order from left to right on the component side.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control input	Receives 4.5V–16V logic-level signal; internal R_G(int) = 2.1Ω limits ringing but requires careful PCB layout for fast switching.
Drain (D)	High-side power output	Connected to exposed copper pad; carries full load current and must be soldered to ≥1"² thermal pad per IR AN-994 guidelines.
Source (S)	Power return / reference node	Serves as common return for gate drive and current sensing; low-inductance routing essential to avoid shoot-through in half-bridge configurations.

Key Features

Feature	Design Value
Logic-level gate threshold	V_GS(th) = 1.0–2.5V - Ensures full enhancement with 3.3V/5V microcontroller outputs without level-shifting circuitry.
Enhanced body diode dI/dt rating	1330A/µs - Allows reliable commutation in hard-switched topologies without external snubbers or diode paralleling.
Low C_{oss eff.}(TR)	1140pF - Reduces turn-off energy loss and improves zero-voltage switching margin in resonant converters.
Avalanche-rated SOA	Validated to 110A × 100V × 100µs - Permits operation in unclamped inductive switching without derating in UPS hold-up circuits.
Lead-free and RoHS-compliant	Meets JEDEC J-STD-020 reflow profile - Compatible with standard Pb-free assembly processes up to 260°C peak temperature.

Applications

DC Motor Drive

High-Efficiency SMPS

IC Role / Device Role / Timing Role: High-side power switch in 3-phase inverter bridge; switched at 16kHz with dead-time control.

Use Value: Low R_DS(on) minimizes I²R losses during 100% duty-cycle conduction; robust dV/dt rating prevents false turn-on during bus transients.

Use Scenario: Secondary-side synchronous rectifier in 1kW telecom PSU with LLC topology.

IC Role / Device Role / Timing Role: Active rectifier replacing Schottky diodes; driven by transformer-coupled gate signals synchronized to primary switches.

Use Value: 50ns trr and low Q_rr reduce reverse recovery losses; 3.4mΩ R_DS(on) cuts conduction loss by >40% vs. 5mΩ alternatives at 80A average current.

Uninterruptible Power Supply

Hard-Switched Industrial Inverter

Use Scenario: 3kVA online UPS with bidirectional DC-link converter and battery charging stage.

IC Role / Device Role / Timing Role: Bidirectional switch in isolated DC-DC stage; conducts 180A continuously during battery discharge mode.

Use Value: 180A continuous rating and 0.40°C/W R_θJC enable stable operation without forced air; avalanche energy rating supports fault clearing during short-circuit events.

Use Scenario: 7.5kW servo drive output stage using six-pack IGBT replacement with discrete MOSFETs.

IC Role / Device Role / Timing Role: Main switching element in 2-level voltage-source inverter; operated at 8kHz with active clamping.

Use Value: Superior R×Q at 4.5V allows faster switching than standard MOSFETs while maintaining low gate drive loss; enhanced dV/dt ruggedness prevents latch-up during bus overshoot.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N10F7	R_DS(on) = 2.2mΩ @ 4.5V, Q_g = 115nC, TO-263 package, 100V rating	Lower on-resistance but higher gate charge increases driver loss above 50kHz; less validated avalanche SOA data available	Preferable for ultra-low-loss DC motor drive where switching frequency ≤20kHz and thermal margin is tight
IXTH180N10L2	R_DS(on) = 3.8mΩ @ 4.5V, Q_g = 72nC, TO-247 package, 100V rating	Higher R_DS(on) but lower Q_g improves high-frequency efficiency; through-hole package eases heatsinking but increases parasitic inductance	Better suited for 100–500kHz SMPS where gate drive loss dominates and board space permits TO-247 mounting

Compared with STL220N10F7 and IXTH180N10L2, IRLSL4030PBF delivers optimal balance of low R_DS(on), moderate Q_g, and comprehensive avalanche characterization-making it preferred for industrial UPS and motor drives requiring proven ruggedness at 10–100kHz operation.

FAQ

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

The IRLSL4030PBF supports 130A continuous drain current at T_C = 100°C with V_GS = 10V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D²PAK package and must be verified against actual board layout and heatsink performance using R_θJC = 0.40°C/W.

Can this MOSFET be used with 3.3V microcontroller GPIO directly?

Yes-the gate threshold voltage range is 1.0V to 2.5V, and R_DS(on) is fully specified at V_GS = 4.5V. While 3.3V may partially enhance the device, full conduction requires ≥4.5V; use of a dedicated gate driver (e.g., TC4420) is recommended for reliable 180A switching at 3.3V logic levels.

Is the body diode suitable for reverse recovery in high-frequency operation?

Yes-the body diode is characterized for 50ns trr at 25°C and 130ns at 125°C, with Q_rr = 88–130nC. Its dI/dt rating of 1330A/µs and soft recovery behavior make it viable for synchronous rectification up to 300kHz, provided gate timing avoids cross-conduction.

Does this part have a specified maximum dv/dt rating?

No explicit dV/dt rating is published, but the device features "improved dynamic dV/dt ruggedness" per its benefits summary and is validated in unclamped inductive switching tests (Fig. 22a/b). Designers should limit dV/dt to ≤50V/ns in practice using gate resistors and layout optimization to prevent spurious turn-on.
