Key parametrics for the BOM line

Single-channel optoisolator with a DC input and a Darlington with base output. The 2500Vrms isolation rating means it provides galvanic isolation between the input and output circuits up to that test voltage — sufficient for many industrial and low-voltage equipment applications where basic isolation is required. Current transfer ratio (CTR) spans 300% minimum to 2600% maximum at a forward current of 1.6 mA. This wide CTR range accommodates varying LED drive currents and load conditions, but the min/max spread means the designer must verify the circuit can tolerate the full range without saturation or insufficient drive at the output. Switching speeds are specified as 1 µs turn-on and 7 µs turn-off typical. These are relatively slow for a digital isolator — the part is suited for DC-level sensing, status feedback, or low-frequency signal isolation rather than high-speed data links.

The tube packaging is the factory shipping format — not a reel, so plan for tube-to-reel transfer if your pick-and-place line is reel-fed. The maximum output voltage is 7V, and the output can sink up to 60 mA per channel — typical for driving a logic gate input or a low-power relay.

Frequently asked questions

What is the current transfer ratio (CTR) of the HCPL0700V?

The CTR is 300% minimum and 2600% maximum, tested at a forward current of 1.6 mA. This wide range means the output drive capability varies significantly with the specific unit and operating conditions.
