That means the photodarlington can saturate a load drawing 100 mA with only 10 mA on the LED side — useful when the microcontroller or PLC output is already budgeted tight. The Darlington with base output gives you access to the base node for external speed-up or bias tweaks if the 5 µs turn-on / 100 µs turn-off is too slow for your switching edge. ## Isolation rating and temperature envelope Rated at 4170 Vrms isolation, this part supports reinforced insulation between the input and output sides — enough for medical patient-contact barriers or industrial mains isolation where the creepage distance across the 6-SMD Gull Wing package must hold off transients. The operating temperature range of -40°C to 100°C covers industrial enclosures and outdoor telecom cabinets without derating. The 80 V maximum output voltage means the Darlington can switch 24 V or 48 V industrial loads with headroom. ## Active production and compliance status It is ROHS3 compliant, which covers the current EU exemption list.","metaTitle":"H11G2SR2M onsemi Optoisolator, 4170Vrms, Darlington Output","metaDescription":"onsemi H11G2SR2M single-channel optoisolator with Darlington output, 4170Vrms isolation, 1000% min CTR at 10 mA.

The Darlington output stage provides this high gain, so a low LED drive current can switch a much larger collector current.
