Product details

Overview

IPP044N03LF2SAKSA1 from Infineon is a logic-level N-channel MOSFET in PG-TO220-3 package, rated for 30 V V_DS, 4.35 mΩ R_DS(on) at V_GS = 10 V, 53 A continuous drain current, and 175 °C junction temperature. It serves as a high-efficiency power switch in DC-DC converters, motor drives, and e-fuse circuits where low conduction loss and fast switching are critical.

For engineers reviewing the IPP044N03LF2SAKSA1 datasheet, IPP044N03LF2SAKSA1 pinout, IPP044N03LF2SAKSA1 application, or IPP044N03LF2SAKSA1 equivalent, key selection criteria include its 4.35 mΩ on-resistance at 10 V gate drive, 13 nC Q_g(0V–4.5V) for logic-level compatibility, 100% avalanche-tested ruggedness, and TO-220 thermal performance with 2.0 °C/W R_thJC.

Technical Context

This StrongIRFET™ 2 device uses trench-gate superjunction technology optimized for low R_DS(on) × Q_g figure-of-merit. Its 1.85 V typical V_GS(th) enables reliable turn-on with 3.3 V or 5 V microcontroller outputs, and its 100% single-pulse avalanche rating (E_AS = 114 mJ) supports robust operation under inductive switching stress.

The MOSFET features integrated body diode with 0.84 V typical V_SD at 30 A and 16 ns t_rr, enabling synchronous rectification in buck converters. Its gate charge profile shows 3.3 V plateau voltage and 13 nC total gate charge up to 4.5 V, minimizing drive power and simplifying gate driver selection.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 24 V system-level power switches
R_DS(on) max	4.35 mΩ at V_GS = 10 V, I_D = 30 A - Enables <1.3 W conduction loss at 53 A continuous load
I_D cont	53 A at T_C = 25 °C - Supports high-current loads with standard TO-220 heatsinking
Q_g(0V–4.5V)	13 nC - Ensures full enhancement with low-voltage logic drivers (e.g., 3.3 V MCU GPIO)
E_AS	114 mJ - Guarantees safe operation during unclamped inductive switching events
R_thJC	2.0 °C/W - Allows direct thermal path to heatsink; enables 75 W P_D at T_C = 25 °C
T_j max	175 °C - Rated for automotive under-hood and industrial ambient environments

Pinout & Package

Package: PG-TO220-3 (standard through-hole, isolated tab, lead-free, RoHS/halogen-free compliant). Tab is electrically connected to Drain.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives gate drive signal; requires ≤20 V absolute max; low input capacitance (1800 pF) reduces driver loading
Pin 2 (Drain) / Tab	High-side power node	Connected to main power rail; tab provides primary thermal path to heatsink; electrically tied to Pin 2
Pin 3 (Source)	Reference and return path	Serves as local ground reference for gate drive; carries full load current; must be routed with low inductance

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1.35–2.35 V ensures full enhancement with 3.3 V or 5 V controllers without level-shifting
100% avalanche tested	Each unit validated to E_AS = 114 mJ - eliminates need for external snubbers in flyback or motor phase-leg designs
Low Q_g/R_DS(on) ratio	13 nC gate charge at 4.5 V with 4.35 mΩ on-resistance - optimizes trade-off between switching loss and conduction loss
Enhanced thermal reliability	175 °C T_j(max) + 2.0 °C/W R_thJC - supports sustained operation in sealed enclosures or high-ambient industrial settings
Integrated robust body diode	t_rr = 16 ns, Q_rr = 36 nC - enables efficient synchronous rectification in high-frequency DC-DC converters

Applications

Brushed DC Motor Driver

Use Scenario: High-efficiency 12–24 V input to 3.3/5/12 V output conversion in telecom power supplies.

IC Role / Device Role / Timing Role: Synchronous high-side power switch operating at 300–1000 kHz switching frequency.

Use Value: 4.35 mΩ R_DS(on) and 13 nC Q_g(0V–4.5V) reduce both conduction and gate drive losses, improving full-load efficiency by ≥1.2% vs. legacy 5.5 mΩ parts.

Use Scenario: H-bridge control of 24 V brushed motors in industrial actuators and robotics.

IC Role / Device Role / Timing Role: Low-side or high-side switching element handling bidirectional 30–50 A peak currents.

e-Fuse / Load Switch

Hot-Swap Controller

Use Scenario: Overcurrent-protected 24 V power distribution in server backplanes and modular PLCs.

IC Role / Device Role / Timing Role: Main pass transistor in active current-limiting circuit with fast fault response.

Use Value: Low R_DS(on) minimizes voltage drop (<130 mV at 30 A), while 16 ns t_rr and low Q_rr suppress oscillation during current-limit transitions.

Use Scenario: Inrush current limiting during live insertion of PCIe cards or storage modules.

IC Role / Device Role / Timing Role: Controlled ramp-up power switch with precise dI/dt management.

Use Value: Gate plateau at 3.3 V enables predictable linear-mode operation; 2.0 °C/W R_thJC allows short-duration SOA compliance during soft-start.

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
STL220N3LLH6	R_DS(on) = 3.2 mΩ @ 10 V but higher Q_g = 24 nC; PG-TSDSON-8 package (surface-mount)	Requires PCB layout redesign; better for high-density, high-frequency SMPS but lacks TO-220 mechanical robustness	Select when board space is constrained and thermal interface uses copper pour instead of heatsink.
IRF3710PBF	R_DS(on) = 24 mΩ @ 10 V; older planar process; no avalanche rating; TO-220AB package	Higher conduction loss limits use to <15 A continuous; unsuitable for inductive switching without snubber	Only consider for cost-sensitive, low-power, non-avalanche-critical legacy replacements.

Compared with STL220N3LLH6 and IRF3710PBF, IPP044N03LF2SAKSA1 delivers optimal balance of low R_DS(on), logic-level drive, proven avalanche ruggedness, and through-hole serviceability-making it preferred for industrial motor control and programmable power delivery where reliability and thermal margin are prioritized over footprint size.

FAQ

Is IPP044N03LF2SAKSA1 suitable for synchronous rectification?

Yes. Its integrated body diode has 0.84 V typical forward voltage at 30 A and 16 ns reverse recovery time, verified per datasheet Table 7. These parameters enable efficient synchronous operation in buck converters up to 1 MHz, provided gate drive timing accounts for Q_rr = 36 nC and t_rr = 16 ns.

What is the maximum recommended gate resistor for 500 kHz switching?

A 10 Ω gate resistor is recommended for 500 kHz operation with 3.3 V logic drivers. This value balances rise/fall times (t_r ≈ 23 ns, t_f ≈ 6.9 ns per Table 5) against ringing suppression, given the device's 1800 pF C_iss and 100 pF C_rss. Lower values risk overshoot; higher values increase switching loss.

Does the TO-220 tab require electrical isolation from the heatsink?

Yes. The tab is internally connected to Pin 2 (Drain), so electrical isolation-using mica or polymer insulator pads plus shoulder washers-is mandatory when mounting to a grounded heatsink. Thermal interface material must maintain dielectric strength ≥500 V to prevent short-circuit failure.

Can IPP044N03LF2SAKSA1 replace IPP040N03LG in existing designs?

Yes, with validation. Both are 30 V TO-220 N-channel MOSFETs, but IPP044N03LF2SAKSA1 has lower R_DS(on) (4.35 mΩ vs. 4.0 mΩ typ.) and higher Q_g (13 nC vs. 11.5 nC). Layout and gate drive strength should be verified, especially for >300 kHz operation where increased Q_g affects driver loading.
