Product details

Overview

IPS20N03L G from Infineon Technologies is an N-channel enhancement-mode MOSFET in TO-251-3 (IPAK) package, rated for 30 V V_DS, 30 A continuous drain current at T_C = 25 °C, and R_DS(on) ≤ 12 mΩ at V_GS = 10 V. It serves as a low-side power switch in DC-DC converters and motor drive half-bridges.

For engineers reviewing the IPS20N03L G datasheet, IPS20N03L G pinout, IPS20N03L G application, or IPS20N03L G equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) max 2.5 V), low conduction loss at 10 V gate bias, thermal performance in surface-mount TO-251, and suitability for high-current switching in industrial power supplies.

Technical Context

This MOSFET employs trench-stop technology to achieve low on-resistance and fast switching with controlled gate charge (Q_g = 24 nC typ). Its body diode exhibits reverse recovery time t_rr = 45 ns and Q_rr = 35 nC, enabling efficient synchronous rectification.

The device features avalanche-rated ruggedness (E_AS = 170 mJ at T_J = 25 °C), integrated ESD protection (HBM Class 2), and operates across junction temperature range –55 °C to 175 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage before breakdown; supports 24 V rail systems with margin.
I_D (continuous)	30 A at T_C = 25 °C - Sustains high load current with TO-251 thermal pad soldered to PCB copper.
R_DS(on)	≤12 mΩ at V_GS = 10 V - Enables <1 W conduction loss at 30 A, reducing heatsink requirements.
V_GS(th)	1.0–2.5 V - Fully enhances with standard 3.3 V or 5 V logic-level drivers without gate boosters.
Q_g	24 nC typ - Determines gate driver power and switching speed; enables ~100 kHz operation with moderate driver strength.
t_rr	45 ns - Limits reverse recovery losses during hard-switching; critical for synchronous buck efficiency.

Pinout & Package

IPS20N03L G uses the TO-251-3 (IPAK) surface-mount package with exposed drain pad for thermal dissipation. Pin 1 = Gate, Pin 2 = Drain (tab-connected), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate terminal	Controls channel conduction; requires 10 V for full enhancement, compatible with microcontroller GPIOs via level-shifting.
Pin 2 (D)	Drain terminal / thermal pad	High-current output node; tab is electrically connected to drain and must be soldered to PCB ground plane for thermal management.
Pin 3 (S)	Source terminal	Reference node for gate drive; connects to system ground or low-side shunt resistor for current sensing.

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) max 2.5 V enables direct interface with 3.3 V/5 V controllers without external level shifters.
Avalanche energy rating	E_AS = 170 mJ ensures robustness against inductive switching transients in motor and relay loads.
Fast body diode	t_rr = 45 ns and Q_rr = 35 nC reduce switching losses in synchronous rectifier topologies.
Thermally enhanced package	TO-251-3 IPAK with exposed drain pad delivers R_θJA ≈ 50 K/W on 2-layer 1-in² copper, improving power density.

Applications

DC-DC Converters

Motor Drive Half-Bridge

Use Scenario: 12–24 V input buck converter delivering up to 25 A to FPGA or ASIC core rails.

IC Role / Device Role / Timing Role: Low-side synchronous rectifier MOSFET, replacing Schottky diodes to improve efficiency above 90%.

Use Value: 12 mΩ R_DS(on) reduces conduction loss by >60% vs. 40 V Schottky, lowering thermal stress on PCB.

Use Scenario: 24 V brushed DC motor control in industrial actuators with PWM frequency up to 20 kHz.

IC Role / Device Role / Timing Role: Low-side switch in half-bridge configuration, commutated with complementary high-side driver.

Use Value: Fast t_rr minimizes shoot-through risk during dead-time transitions, improving reliability.

Industrial Power Supplies

LED Driver Circuits

Use Scenario: Secondary-side OR-ing circuit in redundant 24 V AC/DC power modules.

IC Role / Device Role / Timing Role: Ideal diode replacement for hot-swap and redundancy applications.

Use Value: Low R_DS(on) cuts forward voltage drop to <300 mV at 20 A, eliminating heat sink and fan requirements.

Use Scenario: Constant-current LED string driver with analog dimming in commercial lighting fixtures.

IC Role / Device Role / Timing Role: High-current PWM switch controlling LED current path in buck-based driver topology.

Use Value: Avalanche rating protects against inductive kickback from long LED cable runs during fault conditions.

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
STP30NF03L	R_DS(on) = 14 mΩ (typ), Q_g = 27 nC - slightly higher conduction and switching loss.	Same TO-220 package; lacks TO-251 surface-mount form factor and thermal pad integration.	Prefer when through-hole assembly or legacy board layout mandates TO-220 footprint.
IRLZ34NPBF	R_DS(on) = 28 mΩ (max), V_GS(th) = 1.0–2.0 V - higher on-resistance but tighter threshold spread.	TO-220AB package; no exposed thermal pad - limits sustained current capability above 15 A.	Choose where ultra-low gate threshold consistency matters more than conduction loss, e.g., battery-powered sensor nodes.

Compared with STP30NF03L and IRLZ34NPBF, IPS20N03L G delivers superior thermal performance via TO-251's integrated drain pad and lowest R_DS(on), making it optimal for space-constrained, high-current industrial power stages requiring surface-mount reliability.

FAQ

What is the maximum pulsed drain current (I_DM) for IPS20N03L G?

The maximum pulsed drain current is 120 A, specified at T_J = 25 °C with pulse width ≤ 10 µs and duty cycle ≤ 1%. This rating supports short-duration surge events such as motor startup or capacitor charging, provided PCB thermal design maintains junction temperature within limits.

Does IPS20N03L G require a gate resistor for stability?

A gate resistor of 10–47 Ω is recommended to dampen ringing caused by gate loop inductance and prevent spurious turn-on. The device's 24 nC gate charge and low input capacitance (C_iss = 1,450 pF) make it sensitive to fast edge rates; proper gate resistance ensures reliable switching without oscillation.

Can IPS20N03L G be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) enables inherent current sharing. For two devices in parallel, ensure matched gate drive paths, symmetrical PCB layout, and shared thermal mass under the drain pads to maintain balanced conduction and avoid thermal runaway.

Is IPS20N03L G RoHS-compliant and halogen-free?

Yes - IPS20N03L G meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The TO-251-3 package uses lead-free matte tin plating and green molding compound, supporting environmentally compliant manufacturing.
