Specifications: The APY258AE is a high-voltage Silicon Carbide (SiC) PhotoMOS SSR in an ultra-compact DIP-4 through-hole package. It is a 1 Form A (SPST-NO) relay capable of switching up to 1500V AC/DC with a 30mA current rating. It has an 88Ω on-state resistance, provides 5000Vrms isolation, and switches in 80μs (on) and 50μs (off). It operates from -40°C to 85℃ and is controlled by 1.33-1.5VDC. Application Scenarios: Targeting high-voltage, low-current applications where an extremely small through-hole footprint is critical. Ideal for high-voltage bias supplies in compact scientific instruments, portable medical devices, high-voltage probe circuits, and as a space-saving isolation component in high-density, high-voltage test and measurement equipment, leveraging SiC reliability in a miniature package.
