Product details

Parametric profile and board-fit

The FOD2712A is a single-channel phototransistor optoisolator in an 8-SOIC package, with a DC input LED and a transistor output rated for 30 V collector-emitter and 50 mA continuous current. The 2500 Vrms isolation rating covers basic galvanic isolation for signal-level separation in industrial control, PLC digital inputs, and power-supply feedback loops. Current transfer ratio (CTR) is specified at 100% minimum and 200% maximum when the LED is driven at 10 mA — this 2:1 spread gives the designer enough margin to guarantee a logic-high at the receiver across temperature and LED aging without overdriving the input.

It is RoHS3 compliant, so it meets the latest EU restriction directive without requiring an exemption. The tube packaging (standard SOIC-8 tube) is the common delivery form for prototype and low-to-mid volume assembly; tape-and-reel variants are available under different order codes.

Frequently asked questions

What are the key differences between FOD2712A and FODM1009?

The FODM1009 is a close functional peer with the same single-channel phototransistor topology and 50 mA output current, but it offers a higher isolation voltage of 5000 Vrms versus the FOD2712A's 2500 Vrms, and a wider operating temperature range up to 110°C. The FOD2712A's lower isolation may be sufficient for basic signal isolation in industrial control, while the FODM1009 suits applications requiring reinforced isolation or higher ambient temperatures. Both share the same 8-SOIC footprint and tube packaging.
