Infineon SP370-23-156: A High-Performance 23 mΩ OptiMOS™ Power MOSFET for Automotive and Industrial Applications
The relentless push for higher efficiency, power density, and reliability in automotive and industrial systems demands continuous innovation in power semiconductor technology. Addressing these challenges head-on, Infineon Technologies introduces the SP370-23-156, a standout member of its esteemed OptiMOS™ family. This power MOSFET is engineered to set a new benchmark with its ultra-low 23 mΩ maximum on-state resistance (RDS(on)) in a robust and compact D2PAK (TO-263) package.
At the heart of the SP370-23-156's superior performance is Infineon's advanced OptiMOS™ technology. This technology platform is renowned for achieving an exceptional balance between the lowest possible RDS(on) and switching losses. The remarkably low 23 mΩ RDS(on) directly translates to minimized conduction losses, a critical factor for enhancing overall system efficiency. This is particularly vital in applications like electric vehicle (EV) DC-DC converters and battery management systems (BMS), where every percentage point of efficiency gain contributes to extended driving range and reduced thermal management overhead.
Beyond its impressive electrical characteristics, the device is designed for the harsh environments typical of automotive and industrial applications. It boasts an AEC-Q101 qualified profile, ensuring it meets the stringent quality and reliability standards required for automotive electronics. Its high maximum junction temperature rating of +175°C allows it to operate reliably under high thermal stress, a common scenario in engine control units, motor drives, and industrial power supplies.
The choice of the D2PAK-7pin package offers significant advantages. It provides a low-profile footprint essential for space-constrained designs while simultaneously offering superior thermal performance. The package's efficient heat dissipation capabilities allow designers to push power limits without compromising system size or reliability. This makes the SP370-23-156 an ideal solution for high-current switching applications such as:
Automotive: BLDC motor control for pumps and fans, electric power steering (EPS), and main inverter systems.
Industrial: Server and telecom power supplies, solar inverters, and automated machinery motor controls.
The Infineon SP370-23-156 exemplifies the pinnacle of power MOSFET design, delivering exceptional efficiency, power density, and ruggedness for the most demanding modern applications.
