Product details

Overview

IPD20N03L from Infineon Technologies is an N-channel logic-level power MOSFET optimized for high-efficiency buck converters, featuring 30 V V_DS, 20 mΩ R_DS(on) at V_GS = 10 V, 30 A continuous drain current, and 175 °C maximum junction temperature. It integrates avalanche and dv/dt ruggedness for reliable operation in fast-switching DC-DC stages of industrial power supplies.

For engineers reviewing the IPD20N03L datasheet, IPD20N03L pinout, IPD20N03L application, or IPD20N03L equivalent, key selection criteria include gate charge × R_DS(on) figure-of-merit (FOM), thermal resistance (R_thJC = 1.7–2.5 K/W), reverse diode forward voltage (V_SD = 1.1–1.4 V), and safe operating area under pulsed conditions.

Technical Context

This MOSFET employs a trench-based OptiMOS™ process enabling low conduction loss and fast switching with Q_g = 8.4–11 nC and Q_gd = 6.4–9.6 nC at V_DD = 15 V, ID = 15 A. Its gate threshold voltage (V_GS(th) = 1.2–2.0 V) ensures robust logic-level drive compatibility with 3.3 V and 5 V controllers.

Thermally, it supports high-power density designs via low R_thJC and rated operation up to 175 °C, with avalanche energy E_AS = 15 mJ (single pulse, ID = 15 A, V_DD = 25 V) and dv/dt immunity of 6 kV/µs - critical for noise-resilient synchronous buck topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage compatible with 24 V input rails and transient margin in buck converters
R_DS(on) @ V_GS = 10 V	15.5–20 mΩ - Enables <1 W conduction loss at 30 A, reducing heatsink requirements
I_D (continuous)	30 A @ T_C = 25 °C - Supports high-current output stages without paralleling devices
Q_g / Q_gd	8.4–11 nC / 6.4–9.6 nC - Low gate drive power demand and reduced switching loss in 500 kHz–1 MHz designs
V_GS(th)	1.2–2.0 V - Ensures turn-on with standard logic-level PWM controllers (e.g., TI UCC289xx, ST L638x)
E_AS	15 mJ - Withstands single-pulse inductive energy during startup/fault without failure
T_j(max)	175 °C - Allows operation in sealed enclosures or high-ambient environments without derating

Pinout & Package

IPD20N03L is housed in a TO-252-3-1 (DPAK) surface-mount package with gull-wing leads, optimized for PCB thermal conduction through the exposed drain pad. The package supports ≤60 W power dissipation at T_C = 25 °C with 6 cm² copper area.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects directly to ground plane or low-side shunt resistor
Pin 2 (Gate)	Control input	Receives PWM signal; requires <12 V drive and low-impedance path to minimize ringing
Pin 3 (Drain)	Power output / high-side switch node	Connected to inductor input; large copper pour required for thermal and current handling

Key Features

Feature	Design Value
N-channel logic-level gate	V_GS(th) ≤ 2.0 V enables direct drive from microcontrollers and low-voltage gate drivers
Low R_DS(on) × Q_g FOM	~310 mΩ·nC - balances conduction and switching losses for high-frequency buck efficiency
Avalanche-rated	15 mJ single-pulse rating eliminates need for external snubbers in inductive load switching
175 °C operation	Enables full-rated current in automotive under-hood or industrial control cabinet environments
dv/dt ruggedness	6 kV/µs immunity prevents false turn-on during high-slew-rate switching transitions

Use Value: 6 kV/µs dv/dt rating prevents spurious turn-on during high-noise PV string switching events.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP20NF03L	R_DS(on) = 24 mΩ @ 10 V; Q_g = 12 nC; T_j(max) = 150 °C	Limited thermal headroom in sealed enclosures above 70 °C ambient	Prefer when cost sensitivity outweighs thermal or avalanche performance needs
IRLZ34NPBF	R_DS(on) = 35 mΩ @ 5 V; Q_gd = 10.5 nC; no specified E_AS rating	Higher conduction loss at >15 A; unsuitable for repetitive surge conditions	Select only for low-current (<10 A), non-avalanche-critical applications

Compared with STP20NF03L and IRLZ34NPBF, IPD20N03L delivers superior thermal capability (175 °C vs. ≤150 °C), higher avalanche robustness (15 mJ vs. untested), and lower R_DS(on) × Q_g, making it optimal for high-reliability, high-frequency buck converters where efficiency and ruggedness are co-prioritized.

FAQ

What is the maximum gate-source voltage rating for IPD20N03L?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±12 V risks permanent gate oxide damage. For reliable logic-level drive, V_GS should be maintained between 4.5 V (guaranteed R_DS(on)) and 10 V (optimal conduction loss), with transient spikes clamped using Zener diodes if needed.

Does IPD20N03L have an integrated body diode, and what are its characteristics?

Yes - it features a monolithic parasitic body diode with V_SD = 1.1–1.4 V at I_F = 30 A and T_j = 25 °C, t_rr = 15–18 ns, and Q_rr = 2–3 nC. This diode supports synchronous rectification but is not optimized for freewheeling-only use; external Schottky diodes are recommended for ultra-low-loss recovery.

Can IPD20N03L be used in parallel configurations?

Yes - its positive temperature coefficient for R_DS(on) (increasing with T_j) enables stable current sharing. Successful parallel operation requires matched layout (symmetrical gate and source paths), individual gate resistors (≥5 Ω), and thermal coupling via shared copper area to avoid thermal runaway.

Is IPD20N03L compliant with lead-free and RoHS requirements?

Yes - it is manufactured in accordance with JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and fully complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free packaging per Infineon's qualified material declaration.
