With the acceleration of technological optimization, the demand for high-power components in various commercial industries is expanding. Among them, the most important are in the industries of 13-string lithium battery protection boards and inverters. The need for devices that control and regulate current—field effect transistors—is urgent. Choosing a pure domestically produced model capable of replacing the STP170N8F7 model used in the circuit of 13-string lithium battery protection boards becomes significant. The field effect transistor market faces modern challenges such as low quality, which includes weak reliability, electromagnetic interference impact, poor safety benefits, and more. These not only disrupt the normal operation of 13-string lithium battery protection boards but also lead to increased maintenance costs. From this perspective, selecting a quality field effect transistor replacement model with appropriate parameters is crucial. When using the STP170N8F7 model field effect transistor in the electronic engineering of 13-string lithium battery protection boards, technicians should focus on its performance parameters, such as whether the current reaches 185A and the voltage reaches 85V. These parameters directly affect the working efficiency of the 13-string lithium battery protection board circuit. Besides these factors, the Vcesat saturation voltage drop and safe operating area (SOA) are also key points of concern. The parameters of 185A and 85V are focal points for designers at 13-string lithium battery protection board manufacturers when searching for pure domestic field effect transistor replacement producers. Their aim is to find manufacturers with exceptionally good quality field effect transistors. 1. Forward maximum continuous current: 120A 2. Static on-resistance: 2.95mΩ (Typ), 4mΩ (Max) 3.
