STP08DP05

STP08DP05 is a high-performance, low-voltage N-channel power MOSFET manufactured by STMicroelectronics, designed for efficient switching applications in modern electronic systems. It features a maximum drain-source voltage (VDS) of 50 V and a continuous drain current (ID) of up to 8 A at 25°C junction temperature, making it suitable for demanding power management tasks. The device exhibits a very low on-resistance (RDS(on)) of just 4.5 mΩ at VGS = 10 V, ensuring minimal conduction losses and high energy efficiency—critical for battery-powered and portable devices. This MOSFET is optimized for fast switching speeds with a typical gate charge (Qg) of 37 nC and low input capacitance, enabling reduced switching losses and improved performance in high-frequency applications such as DC-DC converters, motor drivers, and LED lighting systems. Its advanced trench technology enhances thermal performance and reliability, allowing operation across a wide temperature range from -55°C to +150°C junction temperature. Additionally, the STP08DP05 includes built-in avalanche capability, offering robust protection against voltage spikes and transient overloads. The component is housed in a compact TO-220 package, which provides excellent thermal dissipation and mechanical stability, facilitating easy integration into PCB designs without requiring additional heatsinking in many moderate-power applications. It is also fully compliant with RoHS standards, reflecting STMicroelectronics’ commitment to environmentally responsible manufacturing practices. Commonly used in consumer electronics, industrial automation, automotive systems, and power supplies, the STP08DP05 excels in applications requiring high efficiency, small footprint, and reliable operation under varying load conditions. Its versatility supports both synchronous rectification and buck converter topologies, making it an ideal choice for designers seeking to reduce system complexity while improving power density and overall performance.
