在焊接和装卸MOSFET期间,人们关心的问题是MOSFEI能否完好无损.尽管这种担心对于小信号器件来说是有充分理由的,但是大部分功率MOSFET历来都被看作是十分耐用的.在数据资料中,所标定的绝对最大栅极-源极电压一般只有±20V.栅/源极结构相当于一个实际上的电容,对于IRF530,它约为1000pF.假若烙铁采用隔离变压器,则烙铁的金属端部形同与电容串联的电压源(见图 The concern during soldering and handling of MOSFETs is whether the MOSFEI can be left intact.Although this concern is justified for small signal devices, most power MOSFETs have historically been regarded as extremely durable In the data sheet, the specified absolute maximum gate-source voltage is typically only ± 20 V. The gate / source structure corresponds to a real capacitor, which is about 1000 pF for the IRF 530. If the soldering iron uses an isolation transformer, then the soldering iron The metal end is the same voltage source in series with the capacitor (see Figure
