Dual Darlington in an 8-pin SMD — what the ratings deliver
The ILD755-2X007T is a two-channel Darlington-output optocoupler in an 8-SMD Gull Wing package. Each channel's output transistor can sink up to 60 V, and with a minimum current transfer ratio of 1000% at just 1 mA forward current, a microcontroller pin driving the input LED only needs to supply a fraction of a milliamp to switch a 10 mA load on the output side. The 5300 Vrms isolation rating means it provides reinforced galvanic isolation between the input and output circuits — suitable for separating a low-voltage control side from a higher-voltage or noisy power stage in industrial controls, motor drives, or isolated sensor interfaces.
Surface-mount Gull Wing leads on an 8-pin SMD package (8-SMD, Gull Wing) — the footprint matches a standard SO-8 wide-body layout. The lead pitch is 1.27 mm, and the package body is roughly 9.9 mm × 6.0 mm. Reflow profile follows standard JEDEC MSL for moisture sensitivity; no special handling beyond normal SMT bake-out if the shelf life has been exceeded.
The operating temperature range of -55°C to 100°C covers most industrial and automotive under-hood environments, though it lacks an explicit AEC-Q automotive qualification on the record.
