Product details
Overview
IAUS300N08S5N014ATMA1 from Infineon Technologies is an 80 V, 300 A, 1.4 mΩ OptiMOS™-5 N-channel power MOSFET in PG-HSOG-8-1 package, designed for high-current synchronous rectification and motor drive half-bridge legs. It delivers 300 W power dissipation at TC = 25 °C, supports 1200 A pulsed drain current, and features integrated avalanche-rated body diode with 600 mJ single-pulse energy rating.
For engineers reviewing the IAUS300N08S5N014ATMA1 datasheet, IAUS300N08S5N014ATMA1 pinout, IAUS300N08S5N014ATMA1 application, or IAUS300N08S5N014ATMA1 equivalent, key selection criteria include RDS(on) ≤ 1.4 mΩ at VGS = 10 V / ID = 100 A, thermal resistance RthJC = 0.5 K/W, and gate charge Qg = 144–187 nC for high-frequency switching in automotive traction inverters and industrial UPS systems.
Technical Context
This device employs trench-based silicon MOSFET technology optimized for low conduction and switching losses in hard-switched topologies. Its 1.4 mΩ RDS(on) enables <1.2 V forward drop at 300 A DC, while Qgd/Qgs ratio of ~0.65 supports robust dv/dt immunity in high-side configurations.
Thermal design is enabled by a dedicated source-tab thermal path (RthJC = 0.5 K/W) and operation up to Tj = +175 °C. The integrated body diode exhibits trr = 83 ns and Qrr = 156 nC at IF = 50 A, supporting ZVS-assisted soft switching in resonant converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 80 V - Maximum blocking voltage for 48 V–60 V bus applications with 20 % safety margin |
| RDS(on) | 1.4 mΩ max @ VGS = 10 V, ID = 100 A - Enables <0.14 V conduction loss at 100 A, critical for efficiency in high-current inverters |
| ID (cont) | 300 A @ TC = 25 °C - Supports peak-phase currents in 100 kW+ traction inverters without parallel devices |
| EAS | 600 mJ @ ID = 150 A - Confirmed single-pulse avalanche capability for overvoltage transients in motor control |
| RthJC | 0.5 K/W - Allows direct heatsink mounting with minimal thermal interface resistance for compact thermal design |

| tr/tf | 15 ns / 46 ns - Enables <500 kHz PWM operation with controlled EMI in SiC-complementary designs |
| VSD | 0.9–1.2 V @ IF = 100 A - Low forward voltage reduces freewheeling loss in synchronous rectification |

FAQ
What is the maximum allowable gate-source voltage for IAUS300N08S5N014ATMA1?
The absolute maximum gate-source voltage is ±20 V. Operation beyond ±15 V risks permanent gate oxide damage. Recommended drive range is 0 V to +10 V for standard enhancement-mode switching; negative bias down to –5 V may be used for improved dv/dt immunity in high-side configurations.
Does IAUS300N08S5N014ATMA1 require a gate resistor for reliable operation?
Yes - a gate resistor between 2.2 Ω and 10 Ω is required to dampen ringing and control dV/dt during turn-on/turn-off. Values below 2.2 Ω increase risk of oscillation due to package inductance; above 10 Ω extends switching times unnecessarily, raising dynamic losses.
Can IAUS300N08S5N014ATMA1 be used in parallel configurations?
Yes - its positive temperature coefficient for RDS(on) ensures inherent current sharing. Parallel operation requires matched gate drive paths, symmetrical PCB layout, and individual gate resistors. Derating to 260 A per device is recommended for 10-year reliability at TC = 100 °C.
Is the body diode suitable for continuous freewheeling in synchronous rectification?
Yes - the integrated body diode is rated for 300 A continuous forward current at TC = 25 °C and supports 1200 A pulsed current. Its 83 ns trr and low Qrr make it suitable for synchronous rectification in hard-switched and resonant topologies up to 200 kHz.
