2SK2129 MOSFET Transistor 800V 3A TO-220E

Description

2SK2129 800V 3A MOSFET Transistor TO-220F The 2SK2129 is a silicon N-channel power F-MOSFET designed for high-voltage switching applications. It’s built to handle harsh switching conditions (avalanche-capable device) and to be driven directly from typical gate-drive voltages used in power electronics. The device is aimed at circuits where a compact, through-hole package and robust high-voltage blocking are required — for example contactless relays, solenoid/diving circuits, motor drivers, and switching power supplies. Mechanically the device is supplied in a TO-220 style insulated package (datasheet shows TO-220E) which makes it straightforward to mount on small heatsinks or into power assemblies. Thermal design matters for continuous few-amp operation: the part has a modest thermal resistance to case and a maximum channel temperature rating, so you should plan for heat-sinking if you operate near rated power. The transistor is optimized for reasonably fast switching with good ruggedness (no secondary breakdown) for reliable use in inductive loads. Features: High-voltage N-channel power MOSFET. Avalanche-robust construction for safe switching of inductive loads. Wide gate tolerance for robust gate drive handling. Designed for fast switching (low switching losses). Through-hole TO-220 style packaging for easy mounting and heat-sink attachment. Good ruggedness (no secondary breakdown).
