ISOCOM Introduces Radiation-Tested Optocouplers for Space and Aerospace Systems
ISOCOM Ltd, based in Peterlee, United Kingdom, has developed radiation-tolerant optocouplers designed for use in demanding space and aerospace electronic systems. Manufactured at an AS9100-certified aerospace facility, ISOCOM devices provide high-reliability galvanic isolation for satellite payload electronics, spacecraft control systems, and aerospace instrumentation.
ISOCOM optocouplers have been radiation tested at the European Space Agency’s ESTEC facility in the Netherlands, demonstrating Total Ionizing Dose (TID) tolerance up to 150 krad(Si). These devices are available in analog and digital configurations including phototransistor, photodarlington, and photo logic outputs, and are packaged in metal can, LCC, flat-pack, and dual-in-line formats.
With isolation voltages up to 1500 V RMS, CTR values from 200% to 1000%, and low leakage currents, ISOCOM optocouplers meet the stringent reliability requirements of ESA, NASA, and international space missions.
As a European manufacturer, ISOCOM continues to support the development of radiation-tolerant optoelectronic components for future space exploration and aerospace programs.
