170M4867D Application Field and Working PrincipleThe 170M4867D, a semiconductor fuse designed by PerkinElmer, is a type of electrical fuse specifically designed for the protection of power semiconductor devices, such as Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) or Insulated Gate Bipolar Transistors (IGBTs). This fuse is an important component in power control applications, such as solar and wind power control, electric power quality control, and drives and AC inverter control.The 170M4867D is a low voltage, medium current and ultrafast acting fuse. It has a rated current range of 1.2A to 25A, a rated voltage of 0V to 600V, and a response time of 5μs. It is also compliant with the international standards IEC60127-4 and UL248-14 for semiconductor protection fuses.The design of the 170M4867D fuse consists of an insulating body, lead wires, and links. The insulating body is made of high-temperature epoxy resin, and it contains lead wires with two links on both sides. The links are designed with a short-term withstand time of up to 10,000A, and the lead wires are coated with silver to improve electrical conductivity and provide better heat dissipation.The working principle of the 170M4867D fuse is simple yet efficient. When the rated current of the semiconductor device exceeds its limit, the current flow will cause the fuse to heat up. The heat will cause the silver layer on the lead wires to oxidize, causing the resistance of the wire to increase. This will cause the fuse to break, preventing any further current flow and protecting the semiconductor device from damage.The 170M4867D fuse has a number of features that make it an ideal choice for power control applications. Firstly, its quick response time of 5μs helps protect the system against high-current surges and short-circuits that could potentially cause serious damage or even system failure. Secondly, its robust design ensures reliable and consistent operation over an extended period of time. Finally, the fuse is easy to install and replace.In conclusion, the 170M4867D fuse is a reliable and efficient protection device for power semiconductor devices in a variety of power control applications. With its quick response time, robust design, and easy installation, this fuse is an ideal choice for the protection of MOSFETs, IGBTs, and other power control applications.
