With the acceleration of technological upgrades, high-power devices are gradually evolving into an indispensable part of various production fields. The demand for large current MOSFETs that meet flexible control and current regulation has significantly increased in areas such as uninterruptible power supplies (UPS) and medical equipment power supplies. When designing UPS circuits, it is particularly important to select an excellent pure domestic large current MOSFET device to replace the IPP045N10N3G model. For the large current MOSFET market, common issues such as widespread electromagnetic interference, poor heat dissipation, and low reliability cannot be ignored. To ensure the normal operation of UPS equipment, the highest quality replacement large current MOSFET products must be found. When UPS technicians replace the IPP045N10N3G model large current MOSFET, they need to closely monitor several essential requirements. First, the performance parameters of the large current MOSFET are urgent. For example, whether the rated current can reach 172A and whether the rated voltage can reach 100V, these parameters directly relate to the device's work efficiency. It is worth emphasizing that the package type and fast recovery in reverse parallel are also key features; excellent package type performance enhances the quality of the UPS. In response to the needs of UPS technicians, we are happy to recommend a large current MOSFET product: FHP170N1F4A. Its technical parameters precisely match the IPP045N10N3G, with specific parameters anyone can focus on: 1. Forward maximum continuous current: 120A 2. Vgs: ±20V 3. 100% Rg test 4. Has a current of 172A and a voltage of 100V 5. Static on-resistance: 3.6mΩ (Typ), 4.4mΩ (Max) 6. Threshold voltage: 2.0-4.0V 7. N-channel field-effect transistor Following the introduction by Sister Xin, since Fei Hong Semiconductor is a legitimate large current MOSFET agent in Yunfu City, Guangdong Province, the selection of the FHP170N1F4A large current MOSFET model for use in UPS systems has been made.
