Its minimum current transfer ratio of 1000% at 10 mA forward current means the output can saturate with less than 1 mA of LED drive, which suits low-power microcontroller outputs or high-impedance sensor interfaces. ## Isolation and voltage ratings for industrial bus isolation Rated for 4170 Vrms isolation, the H11G2M provides a galvanic barrier between input and output sides. ## Switching speed and temperature range Turn-on time is 5 µs typical, turn-off time is 100 µs typical — this part is not intended for high-frequency PWM but works well for relay coil driving, DC load switching, or status-signal isolation where the signal changes at sub-kHz rates. The operating temperature range of -40°C to 100°C covers industrial cabinet and outdoor telecom environments. ## Active lifecycle and through-hole package It is supplied in a 6-DIP through-hole package (0.300-inch body width, 7.62 mm pitch) on Tube. The through-hole format is straightforward for hand-assembly or rework, and the base terminal (pin 6) allows external biasing if needed.","metaTitle":"H11G2M onsemi Optoisolator – 4170 Vrms, Darlington Output","metaDescription":"onsemi H11G2M optoisolator: 4170 Vrms isolation, Darlington with base output, 1000% min CTR, 80 V output max, -40°C to 100°C.

The key difference is the minimum CTR: H11G3M is specified at 500% min vs the H11G2M's 1000% min. If your design requires the higher CTR, the H11G2M is the correct choice; otherwise the H11G3M can substitute with a CTR derating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/H11G2M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/H11G2M when reusing this data.
