Specifications: The APV258AEH is a high-voltage, Silicon Carbide (SiC) based PhotoMOS solid-state relay in a compact SMD-6 package. It features a 1 Form A (SPST-NO) configuration capable of switching up to 1500V AC/DC loads with a 45mA current rating. Key parameters include an 180Ω on-state resistance, 5000Vrms isolation for robust safety, fast 80μs (on) / 50μs (off) switching speeds, and a wide operating temperature range of -40°C to 85°C, controlled by a low 1.1-1.5VDC input. Application Scenarios: Ideal for applications requiring high-voltage isolation and reliability, such as medical diagnostic equipment (e.g., ultrasound probes, X-ray generators), industrial ATE (Automatic Test Equipment) for high-voltage signal routing, renewable energy systems (photovoltaic inverter sampling circuits), and power supply modules where safety, noise immunity, and long-term stability in harsh environments are critical. Its SMD package enables high-density, automated PCB assembly.
