| 摘 要： | 达林顿管是一种两级或多级的复合管。功率型的达林顿管的功率级是后极,而后极功率管的δVbe不能直接测量,所以,达林顿管瞬态热阻测量仪器的研发一直是一个的难点。从晶体管的瞬态热阻测量原理出发,研究了达林顿管的热阻测量方法。此方法也可以引申到达林顿管稳态热阻的检测中。

| Abstract: | Darlington transistor is the compound transistor with two or more levels. The power level ofthe Darlington power transistor is back stage. BeeauseVbe of the back stage power transistor can＇t be measured directly, the development of the instrumenl for measuring the transient thermal impedance of Darlington Transistor has been a difficulty. In this paper, the measure method of transient thermal impedance of Darlington Transistor is investigated based on the principle of, the transient thermal impedance measuring of transistors, anti this method ean be extended to the steady-state thermal impedance detection of Darlington transistors. |
