- Abstract: Electronic devices that commonly operate at high altitudes, such as those that make circuits on satellites or aircraft, receive high doses of radiation and are subject to the impact of charged particles that can a®ect its functioning [1]. The main sources of radiation are radiation from solar °ares, electrons, protons, heavy ions and cosmic radiation, composed mainly of protons and alpha particles originated on the galaxy. It is very important to study the methodology for the quali¯cation of components in the environments in which the devices are exposed [1]. Damage to electronic devices can be created through radioactive e®ects, which are basically observed by three mechanisms: Total Ionizing Dose (TID), Single Event E®ect (SEE) and Displacement Damage (DD). This project depicts the in°uence of the ionizing radiation on the operation of the half-wave recti¯er circuit, more speci¯cally in the diodes that compose it. Simulation of the circuit was performed, and then compared with the plaque tests. Both diodes were irradiated encapsulated and also without encapsulation, then tested on the circuit and checked the radiation in°uences [2]. The Shimadzu XRD-6100 X-ray di®ractometer irradiated the two diodes, Recti¯er (DR): 1N4007 and Zener (DZ): 1N4735, with dose rates about 20 rad / min and 10 keV e®ective energy [3]. Diodes were maintained 13 cm from the X-ray source, and were analyzed with PXI-National. The total ionizing dose cumulative was 3490 rad. The results show that there was no signi¯cant change for the diode without removal of the epoxy layer, at all radiation doses. After uncapsulating it were observed di®erences: although the DR varied greatly in its voltage VD, from 0.702 V to 0.599 V, it was no signi¯cant change in the rectifying voltage. The DZ is the diode that dictates the rectifying voltage in the half-wave recti¯er circuit; however, the VZ variation was very small, before -6.37V, after irradiation it was -6.35 V.
