Specifications: The APY210EH is the surface-mount SMD-4 counterpart to the APY210E, delivering identical electrical performance in a package suited for automated assembly. It maintains the 150mA, 350V (AC/DC) rating, 15Ω on-resistance, and high 5000Vrms isolation. Its switching characteristics are also 230μs/50μs. It is engineered for the same industrial temperature range (-40°C to 85°C) and control voltage (1.2-1.4VDC).

Application Scenarios: This SMD version enables the miniaturization of designs requiring robust medium-voltage isolation. It is integrated into modern medical device PCBs (like patient monitors), compact industrial sensor modules, high-density power supply boards, and advanced instrumentation, allowing designers to achieve the same high isolation performance in a smaller footprint for volume production.
