The STP80NF03L-04 is a N-channel, 80V, 0.020 Ohm, logic level, low gate charge PowerMOS transistor from STMicroelectronics. This part has a continuously decreasing on-resistance over its specified -55°C to 150°C temperature range, making it well suited for use in high power switching, motor control, and audio applications. This device also features low gate charge which reduces the switching losses, which are crucial when operating in high frequency systems. In addition, it has a maximum drain-source breakdown voltage of 80V (avalanche voltage) and an extremely low output capacitance, making it an ideal choice for high-power switching applications.
