It provides 5000Vrms of galvanic isolation between a DC input LED and a transistor output, making it a straightforward choice for breaking ground loops in industrial digital I/O, PLC input modules, and AC mains detection circuits. The current transfer ratio (CTR) is specified at 80% minimum and 160% maximum when the forward LED current is 5mA — a tight bin that gives predictable logic-level drive without over-designing the input-side resistor. Output transistor is rated for 70V collector-emitter and 30mA continuous current, with a typical Vce(sat) of 300mV. Rise and fall times of 3µs and 5µs respectively keep switching clean for low-speed optocoupler applications up to about 100 kbps. ## Temperature range and mounting Operating temperature spans -55°C to 100°C, covering industrial and outdoor telecom environments where the board sees wide thermal cycling. The through-hole 4-DIP body (0.300\" lead spacing) is a standard footprint — easy to hand-assemble or wave-solder in legacy production lines. ## Lifecycle and compliance For dual-sourcing, the PS2801C-4-V-A is a surface-mount quad-channel sibling with the same 300mV Vce(sat) and similar CTR, but its 2500Vrms isolation and SOIC-16 footprint are a different board fit.","metaTitle":"PS2561A-1-H-A NEPOC Optoisolator, 5000Vrms, 4-DIP","metaDescription":"PS2561A-1-H-A NEPOC optoisolator: 5000Vrms isolation, transistor output, 80-160% CTR at 5mA, through-hole 4-DIP.
