Based on eGaN\u00ae (enhanced Gallium Nitride) technology, this transistor combines high switching speed, extreme radiation resistance, and compact design\u2014making it ideal for use in satellites, avionics systems, and deep-space missions.<\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"554\" data-end=\"582\"><strong data-start=\"554\" data-end=\"582\">Technological Highlights<\/strong><\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"584\" data-end=\"976\">The EPC7003ASH is a surface-mountable (FSMD-A) transistor with a maximum drain-source voltage of 100\u202fV and a continuous drain current of 10\u202fA. Its particularly low on-resistance (typically 42\u202fm\u03a9) combined with extremely low gate charge (only 2.2\u202fnC) enables high-frequency switching with excellent efficiency\u2014a crucial advantage in space systems where size and power consumption are critical.<\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"978\" data-end=\"1179\">Thanks to its lateral structure, the device features minimal parasitic effects and fast response times. Its small size (only 0.068\u202fg) saves valuable space and weight\u2014both essential in satellite design.<\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"1181\" data-end=\"1223\"><strong data-start=\"1181\" data-end=\"1223\">Radiation Hardening to Space Standards<\/strong><\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"1225\" data-end=\"1636\">Special emphasis is placed on radiation resistance: the EPC7003ASH is hardened against both Total Ionizing Dose (TID) at low and high dose rates, and Single Event Effects (SEE). It can withstand ion doses with a Linear Energy Transfer (LET) of up to 83.3\u202fMeV\/(mg\/cm\u00b2)\u2014even at 100% of the specified operating voltage. Furthermore, the component remains functional up to a neutron exposure of 4\u00d710\u00b9\u2075 neutrons\/cm\u00b2.<\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"1638\" data-end=\"1662\"><strong data-start=\"1638\" data-end=\"1662\">Typical Applications<\/strong><\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"1664\" data-end=\"1752\">The EPC7003ASH is suitable for a wide range of high-reliability applications, including:<\/p>\n<ul style=\"text-align: justify;\">\n<li data-start=\"1755\" data-end=\"1798\">Rad-hard high-efficiency DC\/DC converters<\/li>\n<li data-start=\"1801\" data-end=\"1848\">Electronic motor controllers in space systems<\/li>\n<li data-start=\"1851\" data-end=\"1881\">Power supplies in satellites<\/li>\n<li data-start=\"1884\" data-end=\"1983\">Components for deep-space probes where absolute reliability under extreme conditions is essential<\/li>\n<\/ul>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"1985\" data-end=\"2009\"><strong data-start=\"1985\" data-end=\"2009\">Compact and Reliable<\/strong><\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"2011\" data-end=\"2301\">The hermetically sealed FSMD-A package not only protects against environmental influences but also facilitates integration into existing designs. Electrical connection is made via four pins (Gate, Drain, Source Sense, Source), with the &#8220;Source Sense&#8221; function enabling precise gate control.<\/p>\n<p class=\"\" style=\"text-align: justify;\" data-start=\"2303\" data-end=\"2653\">The EPC7003ASH is a prime example of the synergy between modern semiconductor technology and robust space-readiness. With its excellent electrical performance, high radiation tolerance, and compact form factor, it provides system developers with a reliable solution for demanding applications\u2014from geostationary satellites to interplanetary missions.<\/p>\n<p style=\"text-align: justify;\" data-start=\"2303\" data-end=\"2653\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-18213 aligncenter\" src=\"https:\/\/kamaka.de\/wp-content\/uploads\/2025\/03\/Bild1-350x183.png\" alt=\"\" width=\"350\" height=\"183\" srcset=\"https:\/\/kamaka.de\/wp-content\/uploads\/2025\/03\/Bild1-350x183.png 350w, https:\/\/kamaka.de\/wp-content\/uploads\/2025\/03\/Bild1.png 475w\" sizes=\"auto, (max-width: 350px) 100vw, 350px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the EPC7003ASH, EPC Space is introducing a cutting-edge power semiconductor component designed specifically for harsh space environments.
