Product details

Overview

IPP050N03LF2SAKSA1 from Infineon is a logic-level N-channel MOSFET in PG-TO220-3 package, rated for 30 V V_DS, 4.95 mΩ R_DS(on) at V_GS = 10 V, and 53 A continuous drain current at T_C = 25 °C. It features 100% avalanche testing, 175 °C maximum junction temperature, and is optimized for high-efficiency DC-DC converters and motor control stages.

For engineers reviewing the IPP050N03LF2SAKSA1 datasheet, IPP050N03LF2SAKSA1 pinout, IPP050N03LF2SAKSA1 application, or IPP050N03LF2SAKSA1 equivalent, key selection criteria include R_DS(on) at 4.5 V gate drive, Q_g = 10–15 nC, thermal resistance R_thJC = 2.3 °C/W, and avalanche energy E_AS = 72–143 mJ - all critical for synchronous buck and half-bridge switching designs.

Technical Context

This StrongIRFET™ 2 device uses trench-based silicon technology to achieve low R_DS(on) with fast switching (t_r = 16 ns, t_f = 6.4 ns) and low gate charge (Q_gs = 4.8 nC, Q_gd = 3.2 nC). Its logic-level threshold (V_GS(th) = 1.35–2.35 V) enables direct drive from 3.3 V or 5 V controllers without gate drivers.

The integrated body diode exhibits low V_SD = 0.85–1.0 V at 30 A and fast reverse recovery (t_rr = 15 ns, Q_rr = 33 nC), supporting high-frequency synchronous rectification and bidirectional power flow in battery management systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 24 V nominal bus applications
R_DS(on) max	4.95 mΩ at V_GS = 10 V - Enables <1 W conduction loss at 45 A in TO-220 footprint
I_D cont	53 A at T_C = 25 °C - Supports high-current load switching with minimal heatsinking
Q_g total	10–15 nC at V_GS = 0–4.5 V - Low gate drive power for 500 kHz+ PWM operation
E_AS	72–143 mJ - Withstands single-pulse inductive energy without failure in motor drives
R_thJC	2.3 °C/W - Enables thermal design with case temperature monitoring at 175 °C limit
V_GS(th)	1.35–2.35 V - Ensures reliable turn-on with standard microcontroller GPIOs

Pinout & Package

Package: PG-TO220-3 (standard through-hole, isolated tab, lead-free, RoHS/halogen-free compliant).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Receives logic-level gate drive; low input capacitance (C_iss = 1400 pF) minimizes driver loading
Tab (Drain)	Main power output	Electrically connected to drain; serves as primary thermal path to heatsink
Pin 3 (Source)	Reference node	Common return for gate drive and load current; defines local ground reference

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS ≥ 4.5 V - eliminates need for level-shifting or dedicated gate drivers
100% avalanche tested	Guarantees ruggedness against inductive switching transients in motor and solenoid loads
175 °C rated junction	Supports operation in high-ambient environments (e.g., automotive under-hood, industrial enclosures)
Low Q_gd/Q_g ratio	Q_gd = 3.2 nC / Q_g ≈ 0.32 - improves Miller immunity and reduces switching oscillation risk
Optimized body diode	t_rr = 15 ns, Q_rr = 33 nC - minimizes reverse recovery losses in synchronous rectifier topologies

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP55NF03L	R_DS(on) = 5.5 mΩ @ 10 V; Q_g = 18 nC; TO-220FP package (lower power dissipation)	Slightly higher conduction loss; less suitable for >400 kHz switching due to higher Q_g	Prefer when cost sensitivity outweighs efficiency targets and thermal margin is constrained
IRF3710ZPBF	R_DS(on) = 21 mΩ @ 10 V; V_DS = 100 V; higher voltage rating but significantly higher on-resistance	Better for 48 V bus systems; unsuitable for high-current 24 V designs due to 2.5× R_DS(on)	Select only if system requires >30 V blocking and trade-off in efficiency is acceptable

Compared with STP55NF03L and IRF3710ZPBF, IPP050N03LF2SAKSA1 delivers the lowest R_DS(on) and gate charge in its 30 V class, making it optimal for high-efficiency, high-frequency, and thermally constrained applications where conduction and switching losses must be minimized simultaneously.

FAQ

Is IPP050N03LF2SAKSA1 pin-compatible with earlier StrongIRFET™ generation devices?

No. IPP050N03LF2SAKSA1 uses the PG-TO220-3 package with Gate–Drain–Source pinout (Pin 1–Tab–Pin 3), while legacy StrongIRFET™ 1 devices like IPP050N03LG use identical pinout but differ in R_DS(on) (5.2 mΩ vs. 4.95 mΩ), Q_g (12 nC vs. 10–15 nC), and thermal resistance (2.5 °C/W vs. 2.3 °C/W). Mechanical fit is identical, but electrical performance is improved.

What is the maximum recommended PCB copper area for thermal performance?

The datasheet specifies optimal thermal performance with a 40 mm × 40 mm × 1.5 mm FR4 PCB featuring 6 cm² of 70 μm-thick copper on one layer connected to the drain tab. This yields R_thJA = 40 °C/W. Reducing copper area increases R_thJA to 62 °C/W (minimal footprint); forced airflow or larger copper pours further improve dissipation.

Does IPP050N03LF2SAKSA1 support 3.3 V gate drive in practice?

Yes. With V_GS(th) = 1.35–2.35 V and guaranteed R_DS(on) ≤ 7.5 mΩ at V_GS = 4.5 V, the device achieves usable conduction at 3.3 V gate drive - though R_DS(on) rises to ~12–15 mΩ. For full-rated current (53 A), V_GS ≥ 4.5 V is required per datasheet specifications.

How is avalanche ruggedness validated for this part?

Each IPP050N03LF2SAKSA1 unit undergoes 100% single-pulse avalanche testing per JEDEC JESD22-A109, with E_AS = 72 mJ (I_D = 30 A, R_L = 25 Ω) and 143 mJ (I_D = 15 A, R_L = 25 Ω). Test conditions are monitored in real time; units failing energy threshold are rejected.
