<p><strong>The 682-1Y is no longer qualifed as an M28750/9-001 relay.</strong></p> <p>The 682-1Y is an optically isolated AC solid-state relay designed for power switching applications. It operates with a control input voltage from 3.8 to 32 Vdc and switches AC loads up to 250 Vrms over a frequency range of 40 to 440 Hz. Key features include a 1A output current rating (2A with a heatsink), zero-voltage turn-on for low EMI, and the ability to handle surge currents up to 8 Apk. Optical isolation provides a dielectric strength of 1500 Vac between the input and output. Tested using MIL-PRF-28750 Tesst Methods, and housed in a hermetically sealed metal DIP package, the 682-1Y is ideal for high-reliability military and aerospace applications requiring robust performance in harsh environments.</p>
