The device is part of the OptiMOS™ series, manufactured with advanced silicon technology, and is housed in a compact, surface-mount PG-TO252-3-11 package (also known as DPAK). The IPD50N06S4L12ATMA2 meets automotive AEC-Q101 qualification, ensuring reliability under stringent operating conditions.

Main Characteristics and Technologies of IPD50N06S4L12ATMA2

The IPD50N06S4L12ATMA2 leverages Infineon's OptiMOS™-T2 technology, integrating enhancements specifically aimed at reducing on-state resistance and optimizing switching characteristics. Its maximum R_DS(on) of just 12 mΩ at V_GS = 10 V (and I_D = 50 A) dramatically minimizes conduction losses, contributing directly to improved system efficiency. Additional hallmarks include a low gate charge (total Q_g of up to 40 nC), facilitating faster and more efficient switching, and a robust maximum gate-source voltage of ±16 V, which grants a comfortable margin in strongly driven or high-noise designs. The device is 100% avalanche tested to bolster ruggedness in real-world transients and fault scenarios and is rated to operate up to an elevated junction temperature of 175°C, aligning with high thermal demands. With RoHS and REACH compliance, the device can be confidently specified for environmentally sensitive applications as well.

Maximum Ratings and Operational Guidelines for IPD50N06S4L12ATMA2

Designers specifying the IPD50N06S4L12ATMA2 must consider its absolute maximum ratings:

Continuous drain current: 50 A at T_C = 25°C, de-rating to 36 A at T_C = 100°C

Pulsed drain current: up to 200 A

Maximum avalanche energy: 33 mJ (single pulse)

Maximum power dissipation: 50 W (T_C = 25°C)

Maximum gate-source voltage: ±16 V

Operating and storage temperature range: –55°C to +175°C

Engineers are advised to observe safe operating areas (SOA), especially in switching and motor control topologies where transient overcurrents can arise. Proper thermal management and cautious paralleling (where required) ensure that the device remains within published limits across the load profile.

IPD50N06S4L12ATMA2 Thermal Properties and Mechanical Details

The thermal performance of the IPD50N06S4L12ATMA2 is a crucial aspect for high-power applications. Its thermal resistance from junction to case is rated at 3.0 K/W, supporting efficient heat transfer with appropriate PCB layout and heatsinking. The device’s mounting style (surface mount) and package outline (PG-TO252-3-11) are optimized for automated assembly and thermal conduction, provided there is sufficient copper pour under the drain tab. Devices mounted on minimal PCB footprints or with limited cooling area will exhibit a typical junction-to-ambient thermal resistance around 62 K/W, which can be significantly improved with larger cooling pads or active thermal management.
