Specifications: The APY216E is a compact through-hole DIP-4 relay engineered for ultra-high voltage, low-current isolation tasks. It is rated for 80mA at 600V (AC/DC) with a 35Ω on-state resistance and provides a high 5000Vrms isolation barrier. It switches with a 500μs turn-on and a very fast 20μs turn-off. Designed for demanding conditions, it operates from -40°C to 85°C with a 1.2-1.5VDC control input range.

Application Scenarios: This relay is indispensable for high-voltage instrumentation and control where through-hole mounting is required. It is used in CRT display anode voltage switching, controlling electrostatic filters in air purifiers, providing bias switching in mass spectrometers, and as a protective disconnect in high-voltage probe circuits, ensuring safe and reliable operation in high-potential applications.
