摘　　要：通过T-CAD软件建立了PIN二极管的电学模型和热学模型,模拟了PIN二极管的稳态与瞬态特性。研究了PIN二极管器件在正反偏压和脉冲电压下的电学特性及热学特性,讨论了PIN二极管的I层厚度与温度的关系,模拟得到了不同I层厚度的稳态与瞬态响应曲线、得到了与器件内部温度的关系。模拟结果表明:随着I层厚度的增加,器件内部最高温度增长减慢,器件内部最高温度区由结区位置向器件的中间位置移动。An electric thermal model of PIN diodes was established with the T-CAD software,the steady-state and transient characteristics of PIN diodes have been numerically investigated.The electric thermal properties of PIN diodes were simulated under pulse and stable signals with forward and reverse voltage biases respectively,and the effects of the thickness of the intrinsic layer on the temperature inside the diode were studied with their steady-state and transient response curves.The simulation resuits show that,when the thickness of intrinsic layer increases,the peak temperature inside the diode increases slowly and the position of the high-temperature region moves from the junction to the middle of the diode.
