The ATM3400ANSA is a SOT-23 MOSFET manufactured by Agertech. They are RoHS (Restriction of Hazardous Substances) compliant, meaning they do not contain any hazardous materials and are environmentally friendly. This device has an extremely fast turn-on time and is capable of blocking voltages up to 20V. It is perfect for high switching applications and offers a wide range of current and voltage capabilities. The combination of small size, low on-state resistance, and simple layout makes these MOSFETs ideal for consumer electronics and telecom applications. Additionally, the low capacitance makes them well suited for high frequency switching.
