規格與應用場景
Specifications: The OPT1214EH is a miniature high-isolation switch for medium-voltage circuits. In a tiny SMD-4 package, it handles 130mA at 400V (AC/DC) with a 20Ω on-resistance. Its standout feature is the 5000Vrms isolation, providing a robust safety barrier. It switches with 500μs turn-on and a fast 30μs turn-off. The relay is specified for -40°C to 85°C operation with 1.2-1.4VDC control.
Application Scenarios: This component is indispensable in compact high-voltage designs. It is used for bias supply switching in flyback converters, isolation of feedback circuits in offline power supplies, and as a reliable interface in compact medical devices like ultrasound probes or dental equipment, where high voltage and small size must coexist safely.
