The MA4PK3000-1252 is a 3000 kilovolt PIN diode chip that utilizes advanced processing technologies which assures exceptional and reliable performance in multi-kilowatt switch applications. This PIN diode chip is designed to have low resistance, low loss, low distortion and is capable of dissipating very high power. The chip is manufactured using ultra high resistively, long carrier lifetime, float zone material onto which the P+ and N+ regions are deposited. The epitaxial process is specifically designed and optimized for high voltage PIN diodes and results in better preservation of the carrier lifetime and superior layer to layer interface when compared to a conventional double diffused process. The formation of the I-region thickness is precisely monitored using modern measurement techniques and controls. The MA4PK3000-1252 chip utilizes MACOM’s proprietary Cermachip process which has a hard glass surface that covers all exposed junction and intrinsic surfaces. The result is a hermetically sealed, passivated chip that has been used in many high reliability military and commercial programs. Their electrical and thermal properties have been extensively characterized to assure predictable performance.
