一、3DD175晶体管特性3DD175(企业型号3DF30)系硅NPN型低频高反压大功率晶体管,它广泛用于电源调整、开关、变换以及大电流焊接电源、伺服放大器,还可用于广播、电视的低频功率放大和电子计算机、通讯设备的直流电源等方面.多年来,经许多用户使用反映,该管与国内同类型低大管相比,具有电气性能好(输出特性平坦、h_(FF)线性好,V_(CF(Sat))饱和压降小)参数稳定可靠,抗过载能力强和抗二次击穿性能好等优点.这些都证明了3DD175设计结构是合理的,工艺是成熟的.
First, 3DD175 transistor characteristics 3DD175 (enterprise model 3DF30) silicon NPN type low-frequency high-voltage high-power transistor, which is widely used in power adjustment, switching, conversion and welding of large current power supply, servo amplifier can also be used for radio and television low-frequency Power amplifier and computer, communication equipment, DC power supply, etc .. Over the years, many users reflect the use of this tube compared with the same type of domestic low-large tube, with good electrical performance (output characteristics of flat, h_ (FF) , V_ (CF (Sat)) saturation pressure drop) stable and reliable parameters, strong anti-overload and anti-secondary breakdown performance, etc. These have proved 3DD175 design structure is reasonable, the process is mature.
