Product details

Overview

IPB240N03S4LR9ATMA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-TO263-7-3 package, rated for 30 V V_DS, 0.72 mΩ R_DS(on) at V_GS = 10 V and I_D = 100 A, 240 A continuous drain current at T_C = 25 °C, and 175 °C maximum junction temperature - deployed in automotive high-current motor control and DC-DC converter output stages.

For engineers reviewing the IPB240N03S4LR9ATMA1 datasheet, IPB240N03S4LR9ATMA1 pinout, IPB240N03S4LR9ATMA1 application, or IPB240N03S4LR9ATMA1 equivalent, key selection criteria include ultra-low R_DS(on), 100% avalanche energy rating (750 mJ), thermal resistance R_thJC = 0.65 K/W, and AEC qualification for under-hood automotive use.

Technical Context

This OptiMOS™-T device uses trench-gate superjunction technology to achieve sub-1 mΩ on-resistance with low gate charge (Q_g = 230–300 nC) and optimized capacitance profile (C_iss = 15.4–20.3 nF, C_rss = 0.16–0.32 nF). Its 0.65 K/W junction-to-case thermal resistance enables high-power operation on minimal PCB copper area.

The integrated body diode supports synchronous rectification with t_rr = 62 ns and Q_rr = 100 nC, while 190 A single-pulse avalanche current and 750 mJ E_AS ensure robustness against inductive switching stress in motor drive and power supply applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage for 12 V/24 V automotive systems
R_DS(on) @ V_GS=10 V	0.72–0.92 mΩ - Enables <1 W conduction loss at 240 A in high-efficiency inverters
I_D (continuous)	240 A @ T_C = 25 °C - Supports high-current motor phase legs without parallel devices
E_AS	750 mJ - Withstands single-pulse inductive energy without failure in H-bridge commutation

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
IPB240N03S4HATMA1	R_DS(on) = 0.85–1.05 mΩ (higher), same package and AEC-Q101 rating	Slightly higher conduction loss; suitable where thermal margin exists	Select when lower gate charge (Q_g = 210–270 nC) is prioritized over absolute R_DS(on)
STL240N3LLH6	30 V, R_DS(on) = 0.95 mΩ, non-AEC-Q101, TO-263-7 package	Lacks automotive qualification; limited to industrial/commercial environments	Choose only for cost-sensitive non-automotive designs with identical thermal constraints

Compared with IPB240N03S4LR9ATMA1, the IPB240N03S4HATMA1 trades marginal R_DS(on) increase for reduced Q_g, while STL240N3LLH6 omits AEC-Q101 validation - making the original part uniquely suited for safety-critical automotive power stages requiring both ultra-low on-resistance and qualification assurance.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The IPB240N03S4LR9ATMA1 has a specified maximum junction temperature of +175 °C, validated across its full operating range. This rating is supported by thermal characterization data showing stable R_DS(on) behavior up to 175 °C and guaranteed avalanche performance at elevated temperatures, enabling use in under-hood environments without active cooling.

Does this MOSFET require a negative gate voltage for reliable turn-off?

No. The device features a gate threshold voltage range of 1.0–2.2 V and is fully compatible with 0 V to 10 V gate drive. A negative gate voltage is not required for safe turn-off; however, applying –2 V to –5 V can improve noise immunity in high-dI/dt automotive environments, as confirmed by Infineon's recommended gate drive circuit guidelines.

How is the 750 mJ avalanche energy rating validated?

The 750 mJ E_AS rating is derived from 100% unclamped inductive switching (UIS) testing per JEDEC JESD24-11, using I_D = 120 A and standardized test conditions. Each production lot undergoes statistical sampling for UIS stress, and the value reflects worst-case single-pulse capability at T_j = 25 °C, with derating curves provided in the datasheet for elevated temperatures.

Can this device be used in parallel configurations?

Yes - the device exhibits positive temperature coefficient for R_DS(on) above 100 °C, enabling inherently self-balancing current sharing. Parallel operation requires matched gate drive layout, symmetrical PCB copper pours, and individual gate resistors (≥10 Ω) to dampen oscillation; design guidance is documented in Infineon Application Note AN2015-04.
