Abstract EN
Gamma-irradiation effects on the electrical parameters of the Dlode AC switch (DIAC; PH137 500) and Silicon Controlled Rectifier (SCR; 2N4444) devices have been studied in detail, where gamma-dose up to 137 x 106 rad was found to cause a serious permanent damage on their electrical characteristics.
A pronounced increase in the break-over voltage (from 31.5 V to 35 V), holding-current (from 13 mA to 53 mA) and holding voltage (from 22 V to 32 V) of the DIAC is noticed.
Besides, a severe decrease in the dynamic break-over voltage range (from 10 V to 2.5 V) and negative resistance (from —750 ohm to —168 ohm) is also observed.
Exposing the SCRs to gamma-radiation similarly causes their turn-on voltage and forward voltage drop values to increase from 0.80 V to 2.8 V and from 1.40 V to 4.50 V respectively.
Additionally, the holding current increases to 18 mA although its initial value is 3.5 mA.
For the two devices, the linear dependence and high sensitivity of their electrical parameters to gamma-dose suggest the application of such devices in the field of radiation dosimetry.
