Product details

Active production — no obsolescence concern

The FODM1008: ROHS3 compliant, so it passes the environmental compliance check for new designs and replacement builds alike.

5 kV isolation for mains-referenced circuits

Rated for 5000 Vrms isolation, this optocoupler handles the reinforced insulation requirement between primary-side control logic and secondary-side power stages in off-line supplies, motor drives, and industrial I/O modules. The 4-SMD gull wing package (4-SOP) sits low on the board and keeps creepage distance consistent with the 5 kV rating — no need for a slot or additional clearance cutout in the PCB.

CTR window and switching speed for logic coupling

Current transfer ratio is guaranteed between 130% and 260% at a 5 mA forward current. That window means the output transistor saturates reliably across temperature and LED aging without overdriving the input side. Rise and fall times are 5.7 µs and 8.5 µs typical, which supports switching up to roughly 50 kHz — fine for relay drivers, PLC input isolation, and slow PWM links.

Industrial temperature grade and output ratings

Operating from -40°C to 110°C, the FODM1008 fits outdoor telecom cabinets, factory-floor controllers, and under-hood automotive auxiliary circuits without derating. Output transistor handles up to 70 V and 50 mA continuous, with a Vce(sat) of 300 mV max at rated current — low enough to drive a 5 V logic input directly.

Frequently asked questions

Is the FODM1008 a direct replacement for the FODM1007?

The FODM1008 shares the same 4-SOP package, 5 kV isolation, and transistor output as the FODM1007. The difference is the CTR range: the FODM1008 guarantees 130–260% at 5 mA, while the FODM1007 specifies a different CTR bin. Check your design's minimum CTR requirement before swapping.
