STD40P8F6AG

STD40P8F6AG is a high-performance power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in modern electronic systems. It features a maximum drain-source voltage (VDS) of 40 V, making it suitable for low to medium voltage power management tasks. The device offers a very low on-resistance (RDS(on)) of typically 12 mΩ at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency—critical for battery-powered and high-frequency applications. This MOSFET utilizes an advanced trench technology that enhances gate charge performance and reduces switching losses, enabling faster turn-on and turn-off times. Its optimized gate threshold voltage (VGS(th)) ranges from 1.0 to 2.5 V, allowing compatibility with low-voltage control circuits such as microcontrollers and digital logic drivers. Additionally, the device includes a built-in anti-parallel diode, which simplifies circuit design in applications like synchronous rectification or freewheeling paths. The STD40P8F6AG is packaged in a compact TO-220-3L form factor, providing excellent thermal performance through direct mounting on a heatsink. This makes it ideal for use in environments requiring reliable operation under high current conditions. The device supports continuous drain current (ID) up to 130 A at 25°C junction temperature, with pulsed current capability exceeding 520 A, offering robustness for transient load handling. Common applications include DC-DC converters, motor drives, power supplies, and automotive electronics such as electric power steering and battery management systems. Its high reliability, low RDS(on), and fast switching characteristics make it particularly well-suited for space-constrained designs where thermal management and efficiency are critical. Furthermore, the device complies with RoHS standards and is fully lead-free, aligning with environmental regulations and sustainable manufacturing practices. Engineered for industrial and consumer electronics, the STD40P8F6AG delivers consistent performance across a wide operating temperature range—from -55°C to +175°C—ensuring stable functionality in harsh environments. Its rugged construction and proven process technology from STMicroelectronics guarantee long-term reliability and reduced system downtime.
