The K42A12N1 is an N-channel MOSFET from Toshiba Semiconductor and Storage. It has a drain-source voltage (VDS) of 120 V and a continuous drain current (ID) of 42 A at a case temperature (TC) of 25 °C. The K42A12N1 is designed for use in a variety of applications, including power supplies, motor control, and automotive electronics.

One of the key features of the K42A12N1 is its low on-resistance (RDS(on)). The RDS(on) is the resistance between the drain and source terminals when the MOSFET is turned on. A low RDS(on) means that the MOSFET can conduct more current with less power loss. The K42A12N1 has a typical RDS(on) of 0.020 Ω at a gate-source voltage (VGS) of 10 V.

Another key feature of the K42A12N1 is its fast switching speed. The switching speed is the time it takes for the MOSFET to turn on and off. A fast switching speed is important for applications where the MOSFET needs to switch between on and off states frequently. The K42A12N1 has a typical rise time of 10 ns and a typical fall time of 15 ns.

The K42A12N1 is available in a variety of packages, including the TO-220SIS package. The TO-220SIS package is a through-hole package that is well-suited for high-power applications.
