Product details

Overview

IPP020N03LF2SAKSA1 from Infineon is a 30 V, logic-level N-channel MOSFET in PG-TO220-3 package, featuring 2.05 mΩ R_DS(on) at V_GS = 10 V, 125 A continuous drain current, 175 °C maximum junction temperature, and 100% avalanche tested. It serves as a high-efficiency power switch in DC-DC converters, motor drives, and e-mobility on-board chargers.

For engineers reviewing the IPP020N03LF2SAKSA1 datasheet, IPP020N03LF2SAKSA1 pinout, IPP020N03LF2SAKSA1 application, or IPP020N03LF2SAKSA1 equivalent, key selection criteria include R_DS(on) at 4.5 V, gate charge (Q_g = 54 nC), thermal resistance (R_thJC = 1.1 °C/W), and avalanche energy rating (E_AS = 338 mJ).

Technical Context

This StrongIRFET™2 device uses trench-based silicon technology optimized for low conduction and switching losses in high-current, high-frequency synchronous rectification and half-bridge topologies. Its logic-level gate threshold (V_GS(th) = 1.35–2.35 V) enables direct drive from 3.3 V/5 V controllers without level-shifting.

The MOSFET integrates a robust body diode with t_rr = 20 ns and Q_rr = 63 nC, supporting ZVS operation in resonant converters. Thermal design is enabled by its low R_thJC and 40 mm × 40 mm PCB cooling footprint specification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 24 V automotive and industrial bus applications
R_DS(on) max	2.05 mΩ at V_GS = 10 V - Enables <1.5 W conduction loss at 70 A in TO-220 footprint
I_D cont	125 A at T_C = 25 °C - Supports high-current output stages without paralleling
Q_g	54 nC - Determines gate driver power requirement and switching speed in hard-switched SMPS
E_AS	338 mJ - Confirmed single-pulse avalanche capability for inductive load protection
R_thJC	1.1 °C/W - Allows precise junction temperature estimation under 136 W dissipation
T_j max	175 °C - Enables operation in under-hood and industrial environments with derating

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 input	Receives gate drive signal; low input capacitance (C_iss = 4700 pF) reduces driver loading
Pin 2 (Drain) + Tab	High-side power node	Tab provides primary thermal path and high-current drain connection; electrically tied to Pin 2
Pin 3 (Source)	Reference return	Serves as local ground reference for gate drive and current sensing; low-inductance layout critical

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V - compatible with 3.3 V microcontrollers and PWM ICs
100% avalanche tested	Guaranteed E_AS ≥ 338 mJ - eliminates need for external snubbers in inductive switching
Low Q_g/R_DS(on) ratio	54 nC / 2.05 mΩ = 26.3 nC/mΩ - balances switching loss vs. conduction loss in 100–500 kHz designs
Enhanced body diode	t_rr = 20 ns, Q_rr = 63 nC - reduces reverse recovery loss and EMI in synchronous buck and LLC converters

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) = 2.2 mΩ @ 10 V; Q_g = 48 nC; PG-TO220FP package (full-pack, non-isolated tab)	Lower gate charge improves switching efficiency but requires isolation for heatsink mounting	Select when gate drive power budget is tighter and mechanical isolation is managed externally
IRF1404ZPBF	R_DS(on) = 3.8 mΩ @ 10 V; Q_g = 131 nC; legacy TO-220AB, no avalanche rating	Higher conduction loss and untested avalanche performance limit use in safety-critical or high-reliability systems	Consider only for cost-sensitive, non-automotive applications with ample thermal margin

Compared with STL220N3LLH6 and IRF1404ZPBF, IPP020N03LF2SAKSA1 delivers superior R_DS(on)/Q_g trade-off, guaranteed avalanche ruggedness, and 175 °C operation-making it optimal for thermally constrained, high-reliability power stages where efficiency and robustness are co-prioritized.

FAQ

What is the maximum gate-source voltage rating for IPP020N03LF2SAKSA1?

The absolute maximum gate-source voltage is ±20 V. Exceeding this value risks permanent gate oxide damage. Recommended operating range is –10 V to +15 V, with typical gate drive at 0 V (off) and +10 V (fully enhanced). The device's logic-level threshold (1.35–2.35 V) allows safe operation with 3.3 V or 5 V controllers when using appropriate gate resistors and clamping.

Is IPP020N03LF2SAKSA1 suitable for synchronous rectification in LLC resonant converters?

Yes. Its low R_DS(on) (2.05 mΩ), fast body diode (t_rr = 20 ns, Q_rr = 63 nC), and low Q_g (54 nC) make it well-suited for secondary-side synchronous rectification in 100–300 kHz LLC converters. The 175 °C rating supports high ambient temperatures common in enclosed power supplies, and the 100% avalanche test ensures reliability during transient overvoltage events.

How does the PG-TO220-3 package differ from standard TO-220AB in thermal performance?

The PG-TO220-3 package features an isolated metal tab (electrically separated from the drain pin), enabling direct mounting to grounded heatsinks without insulation hardware. Its R_thJC is specified at 1.1 °C/W-identical to standard TO-220AB-but the isolation allows safer, lower-thermal-resistance mounting in high-voltage systems. Mechanical dimensions and PCB footprint remain fully compatible.

Does IPP020N03LF2SAKSA1 require a gate resistor for safe operation?

Yes-a gate resistor is required to control dV/dt and prevent oscillation or shoot-through in bridge configurations. Typical values range from 2.2 Ω to 10 Ω depending on switching frequency and driver strength. Lower values (≤5 Ω) are recommended for high-frequency operation (>200 kHz) to minimize switching time, while higher values improve EMI and reduce gate driver stress in lower-frequency, high-current applications.
