The MOSFET is the core function of an online UPS. Which MOSFET manufacturer can provide a model that can replace the STP170N8F7 MOSFET for use in the circuit diagram of an online UPS? Currently, MOSFET products face challenges such as declining brand reputation and low reliability, which are closely related to the reliable operation of online UPS equipment. Selecting a good replacement MOSFET is important. When selecting the STP170N8F7 MOSFET, online UPS technicians need to pay attention to its performance parameters, such as whether the rated current can reach 185A and whether the voltage can reach 85V. These indicators are closely related to the work efficiency of the online UPS circuit. It should also be noted that the saturation voltage drop and the gate threshold voltage (VGE(th)) are also key points of concern. FHP170N8F3A has successfully replaced the STP170N8F7 and is widely used by many international online UPS manufacturers. It is strongly recommended to understand its detailed technical parameters: 1. 185A current, 85V voltage 2. Fast switching capability 3. Maximum forward pulse current: 480A 4. N-channel enhancement mode field effect transistor 5. Vgs: ±20V 6. VGS（th）: 2.0-4.0V Reliable and high-quality MOSFET! Fei Hong Semiconductor strongly recommends using the FHP170N8F3A MOSFET to enhance the power switch capability of the online UPS circuit. This MOSFET with a rated parameter of 185A and 85V meets the actual needs of solving problems such as declining product brand reputation and low reliability. The spirit of Fei Hong Semiconductor is sincere, allowing online UPS manufacturers to confidently order custom FHP170N8F3A MOSFETs.
