Description
FODM217A is a single-channel digital optocoupler (optical isolator) in the FODM family. It provides galvanic isolation between the input LED and the output logic, allowing a signal to cross a high-voltage barrier safely. The output is TTL/CMOS-compatible and can be powered from 3.3–5 V logic. Typical uses include isolating microcontroller inputs, sensor signals, or gate-drive/control signals in power electronics. It targets robust isolation (high isolation voltage) and good common-mode transient immunity, packaged in a compact 6-pin form factor (DIP or SMD variants). For exact parameters—CTR, propagation delay, input current, and maximum ratings—see the FODM217A datasheet.
Features
FODM217A Features (concise):
- 1-Form-A photomos relay: optically isolated MOSFET output, no mechanical contacts
- Output: bidirectional MOSFET pair; no contact bounce, silent switching
- Isolation: high input-to-output isolation (typically several kV RMS)
- Voltage/current ratings: VDS up to ~60 V; ID up to tens of mA (typical ~50 mA)
- Low on-resistance: low RDS(on) when ON for efficient switching
- Input drive: LED input requires only a few milliamps to turn on
- Fast switching with no wear; highly reliable
- Packages: 8-pin DIP or compact SOP/SO-8 options
- Operating temp range: suitable for standard industrial temps (often -40°C to 85°C)
- Compliance: RoHS/lead-free
Note: exact electrical ratings (VDS, ID, RDS(on), IF) vary by variant; consult the latest datasheet for precise numbers.

Pinout
Pin count: 8 pins (DIP-8/SO-8).
Function: Dual optocoupler with MOSFET outputs (photocoupler for isolating two digital signals). Pinout (typical):
- Pins 1–2: LED1 anode/cathode
- Pins 3–4: LED2 anode/cathode
- Pins 5–6: MOSFET OUT1 (drain/source)
- Pins 7–8: MOSFET OUT2 (drain/source)
Notes:
- Output MOSFETs are open; use external pull-ups as needed.
- No internal supply on the output side; inputs drive the isolated outputs. Verify exact pinout from the specific datasheet variant.
