10 Mbps digital isolation with 10 kV/µs transient immunity
The onsemi HCPL2630SDV is a two-channel optocoupler with a 10 Mbps data rate and open-collector output, designed for unidirectional logic-level isolation in digital communication links such as fieldbus interfaces, encoder feedback, and PLC-to-sensor connections. The 2500 Vrms isolation voltage provides basic safety insulation per IEC 60950-1, sufficient for industrial equipment where the input logic side and the output load side must be galvanically separated.
Timing and output drive for 5 V logic systems
Propagation delay is 75 ns max for both low-to-high and high-to-low transitions, with a 50 ns rise time and 12 ns fall time — the output switches fast enough to sustain 10 Mbps NRZ data without significant pulse-width distortion.
onsemi has designated the HCPL2630SDV as obsolete. No warranty or production guarantee from the factory applies. For a new design, a functionally equivalent optocoupler with a 10 Mbps data rate, open-collector output, and 2500 Vrms isolation in an 8-SMD Gull Wing package should be evaluated — the board layout and supply rails are the primary constraints.
