Rated for the full industrial temperature range of -55°C to 100°C, it suits environments where the optocoupler sits near the board edge or in a non-conditioned enclosure. ## CTR and switching-speed limits The 8 mA per-channel output ceiling means the CTR range is the real constraint for driving downstream logic. Typical turn-on time is 450 ns, turn-off 300 ns — fast enough for 1 MHz data isolation but marginal for 10 MHz clock isolation without pulse-swallowing on the falling edge. ## Obsolete — sourcing through surplus channels onsemi has marked the HCPL2531SDV as obsolete. Quantities are lot-specific; each quote confirms date code, package condition, and traceability before shipment.","metaTitle":"onsemi HCPL2531SDV Optoisolator, 2500Vrms, 2-Ch","metaDescription":"onsemi HCPL2531SDV dual-channel transistor output optocoupler, 2500Vrms isolation, 8-SMD Gull Wing.
