Product details

Active production — no obsolescence risk for BOM planning

The FODM217AR2: ROHS3 compliance is confirmed, so the part meets the latest EU restriction requirements without exemption expiry concerns.

The 1-channel transistor output with a maximum collector-emitter voltage of 80V and continuous output current of 50mA per channel handles standard logic-level signals (5V, 3.3V) and small relay or LED loads directly.

Current transfer ratio — 80% to 160% at 5mA forward current

The CTR is specified as 80% minimum and 160% maximum at If=5mA — a tight bin that guarantees the output transistor saturates with a standard 5mA LED drive, even at the low end of the temperature range. This makes the part predictable across reel-to-reel variation.

Switching speed and temperature range

Rise and fall times are 2µs and 3µs typical, with turn-on and turn-off times both 3µs typical — adequate for switching frequencies up to about 100kHz and for isolating slow serial buses (UART, I²C at 100kHz) or PWM signals in motor drives.

The supplier device package is designated 4-SOP, which is the same mechanical outline. Available in both Tape & Reel (for automated pick-and-place) and Cut Tape (for prototyping and small runs), giving flexibility in procurement quantity.

Frequently asked questions

Where can I buy FODM217AR2 and check availability?

The FODM217AR2 is an active-production part from onsemi. Submit an RFQ for a firm lead-time and price.

Is FODM217AR2 a drop-in replacement for FODM1009?

No — while both are 1-channel transistor-output optoisolators in surface-mount packages, the FODM1009 offers 5000Vrms isolation versus 3750Vrms, and its switching speeds are slower (5.7µs rise, 8.5µs fall). The pinout may also differ; verify the footprint and isolation requirements before substituting.

What compliance documentation does onsemi provide for FODM217AR2?

onsemi confirms ROHS3 compliance for this part. For additional documentation such as REACH, UL recognition, or IEC 60747-5-5 certification, refer to the official onsemi datasheet or contact our sourcing team — we can supply the manufacturer's compliance declaration upon request.
