At the minimum end, 500% means a 1.6 mA LED drive yields 8 mA at the output — enough to saturate a TTL or CMOS gate input. At the maximum end, 2600% delivers 41.6 mA, which directly drives a small relay or a PLC input module without an external transistor stage. The 2500 Vrms isolation rating per IEC 60747-5-5 qualifies it for reinforced insulation in industrial bus isolators, motor-drive feedback paths, and medical equipment where the patient-accessible circuit must be galvanically separated from the mains side. ## Switching speed — the asymmetry to budget for Turn-on time is 300 ns typical, but turn-off stretches to 1.6 µs. That 5:1 ratio means the output falls slower than it rises — the useful pulse-width modulation frequency tops out around 300 kHz before the off-time compresses the duty cycle. For a 100 kHz signal the output still resolves cleanly; above 500 kHz the falling edge bleeds into the next cycle. The Darlington output stage saturates at roughly 1 V collector-emitter at 60 mA, leaving a 17 V swing into an 18 V load. The 60 mA continuous output per channel is the DC limit; pulsed loads at low duty cycle can exceed this, but the junction temperature rise in the 8-SOIC package sets the practical ceiling. ## Package and temperature grade Housed in the standard 8-SOIC wide-body (0.154-inch width, 3.90 mm), the footprint matches the industry-standard SOIC-8 land pattern. Supplied in tube packaging — not tape-and-reel. For automated pick-and-place, a tube-to-reel transfer is needed unless the line feeds from tubes directly. ROHS3 compliant with no exemption conflicts for EU or California market shipments.","metaTitle":"onsemi HCPL0701V Optocoupler, Darlington Output, 2500 Vrms","metaDescription":"onsemi HCPL0701V single-channel Darlington optocoupler in 8-SOIC. 500% to 2600% CTR at 1.6 mA, 2500 Vrms isolation.

The HCPL0701V's Darlington output provides much higher current gain — 500% to 2600% CTR vs the FODM1009's transistor-stage gain — so they are not direct drop-in replacements. For a Darlington alternative, look at the HCPL0730 or HCPL0738 from the same onsemi family."},{"question":"Will HCPL0701V drop into a board designed for FODM1009?","answer":"Both parts use the standard 8-SOIC wide-body footprint (0.154-inch width), so the PCB land pattern is identical. However, the HCPL0701V's Darlington output saturates at a higher voltage (about 1 V vs 300 mV for the FODM1009 transistor), and the CTR is an order of magnitude higher. Verify the downstream input threshold and pull-up resistor — the Darlington's higher saturation voltage may not pull a 3.3 V logic input low enough if the resistor is too small."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/HCPL0701V","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/HCPL0701V when reusing this data.
