Product details

Overview

IAUS240N08S5N019ATMA1 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode power MOSFET in PG-HSOG-8-1 package, featuring 80 V V_DS, 1.9 mΩ R_DS(on) at V_GS = 10 V and I_D = 100 A, 100% avalanche tested, and rated for 175 °C operation - deployed in automotive high-current DC-DC converters and motor control inverters.

For engineers reviewing the IAUS240N08S5N019ATMA1 datasheet, IAUS240N08S5N019ATMA1 pinout, IAUS240N08S5N019ATMA1 application, or IAUS240N08S5N019ATMA1 equivalent, key selection criteria include R_DS(on) stability over temperature, single-pulse avalanche energy (400 mJ), gate charge profile (Q_g = 100–130 nC), and MSL1 reflow compatibility up to 260 °C.

Technical Context

This OptiMOS™-5 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V/48 V automotive systems. Its 0.65 K/W R_thJC enables high current handling (240 A continuous at T_C = 25 °C) with minimal thermal derating.

The MOSFET integrates a robust body diode with t_rr = 71 ns and Q_rr = 126 nC at I_F = 50 A, supporting synchronous rectification and hard-switched topologies without external freewheeling diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	80 V - supports 48 V battery rail systems with 2× safety margin against transients.
R_DS(on)	1.9 mΩ max at V_GS = 10 V, I_D = 100 A - enables <1.9 W conduction loss at 100 A.
I_D (cont.)	240 A at T_C = 25 °C - delivers high peak power in short-duration load dumps or motor startup.
E_AS	400 mJ single-pulse - withstands inductive energy spikes in motor drive fault conditions.
Q_g	100–130 nC - determines gate driver power requirement and switching speed trade-off.
t_r/t_f	12 ns / 36 ns - enables >500 kHz switching in resonant or phase-shifted topologies.
R_thJC	0.65 K/W - allows direct heatsink mounting with predictable junction-to-case thermal path.

Pinout & Package

Package: PG-HSOG-8-1 - surface-mount, thermally enhanced 8-pin SO-style leadframe with exposed drain tab for low-inductance, high-current PCB routing and direct thermal coupling to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	High-impedance control input requiring <130 nC total charge for full turn-on.
Drain Tab	Drain (Power)	Exposed metal pad - primary current path and thermal interface; must be soldered to large copper area.
Pins 2–8	Source	Parallel source terminals reduce package inductance and improve current sharing in parallel configurations.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain and chassis applications per stress test requirements.
100% avalanche tested	Each unit subjected to single-pulse E_AS stress - ensures robustness in inductive switching faults.
MSL1 rating	Compatible with standard lead-free reflow profiles up to 260 °C peak, eliminating moisture sensitivity concerns.
175 °C operating temperature	Enables placement near hot engine compartments or under-hood power modules without derating.
Ultra-low R_DS(on)	1.9 mΩ at 100 A reduces conduction loss by >35% vs. prior-generation OptiMOS™-4 devices.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IAUZ40N08S5N022ATMA1	Higher R_DS(on) (2.2 mΩ), lower I_D (190 A), same 80 V rating and PG-HSOG-8-1 package.	Suitable for cost-sensitive 48 V systems with <180 A peak demand and relaxed thermal constraints.	Select when 0.3 mΩ higher on-resistance is acceptable for lower gate charge (Q_g = 85 nC) and reduced driver complexity.
IPB180N08S5H5ATMA1	Same R_DS(on) (1.9 mΩ), higher V_DS (100 V), TO-263-7 package with different thermal interface and pinout.	Better suited for industrial UPS or solar inverters requiring 100 V rating and through-hole assembly.	Choose only if 100 V breakdown margin is required and board layout accommodates larger footprint and non-MSL1 reflow profile.

Compared with IAUZ40N08S5N022ATMA1, IAUS240N08S5N019ATMA1 delivers 50 A higher continuous current and 20 mJ more avalanche energy; versus IPB180N08S5H5ATMA1, it offers MSL1 reflow compatibility and superior thermal resistance (0.65 vs. 0.95 K/W), critical for compact automotive modules.

FAQ

What is the maximum allowable gate-source voltage for IAUS240N08S5N019ATMA1?

The absolute maximum V_GS is ±20 V. Operation beyond this range risks permanent gate oxide damage. Recommended drive voltage is 10 V for full enhancement; 6 V is sufficient for R_DS(on) ≤ 2.0 mΩ but increases conduction loss by ~25% at 100 A.

Does IAUS240N08S5N019ATMA1 require a gate resistor, and what value is recommended?

Yes - a gate resistor controls dV/dt and prevents oscillation. For 100 A switching at 200 kHz, a 3.5 Ω resistor is validated in Infineon's reference design (V_DD = 40 V, R_G = 3.5 Ω). Lower values increase switching speed but raise EMI risk; higher values reduce driver stress but extend t_d(on) to 18 ns.

Can IAUS240N08S5N019ATMA1 be paralleled for higher current capacity?

Yes - its positive temperature coefficient of R_DS(on) (1.9 → 2.5 mΩ from 25 °C to 175 °C) enables stable current sharing. Use matched gate drivers, symmetrical PCB layout, and Kelvin source connections to minimize imbalance; derate total current by 15% for thermal margin in 2-device parallel configuration.

Is the drain tab electrically isolated from the package substrate?

No - the drain tab is internally connected to the MOSFET's drain terminal and is not insulated. It must be electrically tied to the drain net on the PCB and thermally bonded to the heatsink using electrically conductive thermal interface material or isolated via insulating pad if system grounding requires galvanic separation.
