Product details

Overview

IPP14N03LA from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TO220-3-1 package, rated for 25 V V_DS, 30 A continuous drain current at T_C = 100 °C, and 13.9 mΩ R_DS(on) at V_GS = 10 V. It features dv/dt ruggedness (6 kV/µs), 175 °C maximum junction temperature, and optimized gate charge × R_DS(on) figure-of-merit for high-frequency DC/DC converters.

For engineers reviewing the IPP14N03LA datasheet, IPP14N03LA pinout, IPP14N03LA application, or IPP14N03LA equivalent, key selection criteria include its logic-level gate drive compatibility (V_GS(th) = 1.2–2.0 V), low thermal resistance (R_thJC = 3.2 K/W), avalanche energy rating (E_AS = 60 mJ), and RoHS-compliant Pb-free plating.

Technical Context

This MOSFET employs Infineon's OptiMOS™2 process to deliver enhanced switching efficiency in synchronous rectification and primary-side switching topologies. Its low Q_g (6.3–8.3 nC) and low Q_gd/Q_gs ratio support fast, controllable turn-on/turn-off with reduced Miller-induced oscillation risk.

The device integrates a robust body diode with low V_SD (0.98–1.2 V @ 30 A) and minimal Q_rr (≤10 nC), enabling efficient reverse recovery in hard-switched and resonant converter stages without external Schottky supplementation.

Key Specifications

Lead 2 (center)	Gate	High-impedance control terminal; requires <8.3 nC charge for full enhancement
Lead 3 (right) + Tab	Drain	High-current power node; tab is electrically connected to drain and serves as primary thermal interface

Key Features

Feature	Design Value

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
STP30NF20	200 V V_DS, 30 A, R_DS(on) = 36 mΩ @ 10 V - higher voltage rating but 2.6× higher on-resistance	Designed for 100–200 V industrial supplies; unsuitable for 25 V low-loss optimization	Select only if higher breakdown margin is required and efficiency is secondary
IRLZ44N	55 V V_DS, 49 A, R_DS(on) = 22 mΩ @ 5 V - wider V_DS range but higher R_DS(on) and no dv/dt rating	General-purpose logic-level use; lacks specified dv/dt immunity and 175 °C qualification	Acceptable for non-critical 12 V consumer applications; avoid in automotive or high-noise environments

Compared with STP30NF20 and IRLZ44N, IPP14N03LA delivers superior efficiency in 25 V systems due to its 13.9 mΩ R_DS(on), verified dv/dt ruggedness, and JEDEC-qualified 175 °C operation-making it the optimal choice for thermally constrained, high-reliability DC/DC stages.

FAQ

Is IPP14N03LA suitable for 3.3 V microcontroller gate drive?

Yes. With a gate threshold voltage of 1.2–2.0 V and guaranteed enhancement at V_GS = 4.5 V, IPP14N03LA fully turns on using standard 3.3 V GPIO outputs. Its low Q_g (6.3–8.3 nC) ensures fast switching even with weak drivers, though a 1–2 Ω series gate resistor is recommended to dampen ringing.

What is the maximum safe operating area (SOA) limitation at 100 °C case temperature?

At T_C = 100 °C, the device supports 30 A continuous drain current up to V_DS ≈ 1.5 V (limited by R_DS(on)). For V_DS > 5 V, SOA is constrained by pulse energy and thermal time constants - refer to Figure 3 in Rev. 1.91 datasheet for single-pulse SOA curves at varying t_p.

Does IPP14N03LA have avalanche capability, and is it rated for repetitive operation?

IPP14N03LA is rated for single-pulse avalanche energy (E_AS = 60 mJ) under defined test conditions (I_D = 24 A, R_GS = 25 Ω). It is not characterized or guaranteed for repetitive avalanche; circuit design must avoid repeated avalanche events to ensure reliability.

Can the drain-connected tab be electrically insulated from the heatsink?

No. In the PG-TO220-3-1 package, the metal tab is internally bonded to the drain terminal. Electrical isolation requires an insulating washer and shoulder washer kit. Thermal interface material must be non-conductive (e.g., silicone grease with ceramic filler) when mounting to grounded heatsinks.
