Specifications: The APV210EH is the surface-mount SMD-6 version of the APV210E. It shares the same 120mA, 350V rating, 16Ω on-state resistance, and high 5000Vrms isolation. Switching times are 230μs/50μs. It operates from -40°C to 85°C with 1.2-1.4VDC control. Application Scenarios: Provides the same high-isolation performance as the DIP version but in a surface-mount package for automated assembly. Suitable for modern designs of medical device power supplies, industrial sensor interfaces, and high-voltage measurement equipment where board space and manufacturing efficiency are considerations.
