NSS1C301CT

The NSS1C301CT is a high-performance, low-voltage N-channel MOSFET manufactured by onsemi, designed for efficient power management in compact electronic systems. It features a maximum drain-source voltage (VDS) of 30 V and a continuous drain current (ID) of up to 5.2 A at 25°C, making it suitable for applications requiring reliable operation under moderate load conditions. The device exhibits a very low on-resistance (RDS(on)) of just 75 mΩ at VGS = 4.5 V, ensuring minimal conduction losses and high energy efficiency—ideal for battery-powered devices where power conservation is critical. This MOSFET is optimized for fast switching speeds, with a typical gate charge (Qg) of 6.9 nC and a low input capacitance, enabling rapid transitions between on and off states. These characteristics reduce switching losses and support high-frequency operation, which is essential in modern switch-mode power supplies (SMPS), DC-DC converters, and motor control circuits. The integrated body diode offers inherent protection against reverse voltage, enhancing system robustness without the need for external components. The NSS1C301CT is packaged in a compact TO-236-3 (SOT-23) surface-mount format, facilitating easy integration into space-constrained designs such as portable electronics, consumer gadgets, and IoT devices. Its lead-free construction complies with RoHS standards, supporting environmentally responsible manufacturing practices. The device also demonstrates excellent thermal performance due to its low thermal resistance, allowing efficient heat dissipation even under sustained loads. Key features include a threshold voltage (VGS(th)) range of 0.8 to 2.0 V, enabling compatibility with logic-level drivers such as microcontrollers operating at 3.3 V or 5 V. This makes it ideal for direct interfacing with digital control circuits without additional level-shifting components. Additionally, the device provides robust avalanche capability and overcurrent protection through its inherent design, contributing to system reliability in harsh electrical environments. Common applications include buck converters, LED drivers, battery charging circuits, and low-power motor drives in consumer electronics, industrial automation, and automotive systems. Its combination of high efficiency, small footprint, and ease of use positions the NSS1C301CT as a versatile solution for designers seeking to optimize performance, reduce component count, and enhance system longevity in modern electronic designs.
