The DC-input transistor output is rated for 75 V collector-emitter maximum and 30 mA continuous output current. The 3750Vrms isolation rating is the key spec for galvanic isolation in power supplies, motor drives, or PLC I/O — the 4-Mini-Flat package saves board area compared to a standard SOIC-8 while still meeting reinforced isolation requirements for many 240 VAC applications. ## CTR range and switching speed for loop margin Current transfer ratio is specified at 130% minimum to 260% maximum at a forward current of 1 mA. This narrow CTR binning reduces design uncertainty — the designer can calculate LED drive current without over-specifying the input resistor to cover a wide CTR spread. Typical turn-on and turn-off times are 6 µs each, with rise/fall times of 5 µs and 5.5 µs respectively. This suits switching frequencies up to roughly 50 kHz — adequate for isolated gate-drive feedback, AC mains zero-cross detection, or slow digital isolator replacement. The operating temperature range spans -40°C to 125°C, exceeding the standard industrial 105°C ceiling. This part can be used in under-hood automotive electronics (non-AEC-Q100, but the temp grade aligns), outdoor telecom cabinets, or high-ambient factory-floor I/O modules without thermal derating concerns. The forward voltage is 1.35 V typical at 20 mA max forward current. The 400 mV Vce saturation at 30 mA output keeps the on-state voltage drop low in the output transistor, which matters when driving a logic input or a low-power relay coil.","metaTitle":"FODM8801BV onsemi OptoHit™ Optoisolator, 3750Vrms","metaDescription":"onsemi FODM8801BV OptoHit™ optocoupler, 1-channel transistor output, 3750Vrms isolation, 130-260% CTR at 1 mA, -40 to 125°C.

The output transistor is rated for 75 V collector-emitter maximum, so 5 V logic is well within the voltage range. At 1 mA forward current, the 130% minimum CTR means the output can sink at least 1.3 mA — sufficient to pull a 5 V logic input low through a 10 kΩ pull-up resistor. The 6 µs typical switching speed is compatible with UART and slow SPI signals."},{"question":"What is the closest functional equivalent to FODM8801BV?","answer":"Within the OptoHit™ family, the FODM8801C is the same die with the same CTR bin (130-260% at 1 mA), same isolation, and same package — the only difference is the packaging suffix (tube vs tape-and-reel). Outside the family, the FODM121B offers a faster switching time (3 µs typical rise/fall) but a narrower temperature range (-40°C to 110°C) and different CTR binning."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/FODM8801BV","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/FODM8801BV when reusing this data.
