Specifications: The APV256E is the through-hole DIP-6 version of a high-voltage, low-current PhotoMOS SSR. It is a 1 Form A (SPST-NO) relay rated for 80mA at 600V AC/DC. It has a 35Ω on-state resistance, provides 3750Vrms isolation, and switches with 500μs (on) and 20μs (off) times. It operates from -40°C to 85℃ with a 1.2-1.5VDC control input. Application Scenarios: Suited for the same high-voltage, low-current signal switching as the SMD version, but where through-hole mounting is preferred. Common in high-voltage test equipment development, laboratory power supplies, medical device prototyping, industrial instrumentation, and any application requiring safe handling of high potentials with the repairability and thermal mass of a DIP package.
