Product details

Isolation barrier and signal path

The FODM453R2V is a single-channel optoisolator with a 3750Vrms isolation voltage, suitable for galvanic isolation in industrial controls, PLCs, and motor-drive interfaces where the barrier must withstand transient overvoltages without breakdown. DC input drives an infrared LED (1.6V typical forward voltage, 25 mA max forward current) coupled to a phototransistor output rated for 20V maximum and 8 mA continuous per channel. Switching times of 400 ns turn-on and 350 ns turn-off support signal isolation up to approximately 1.3 Mbps, adequate for digital I/O, encoder feedback, and isolated serial links.

Package and temperature range for assembly planning

Housed in a 5-lead 6-SOIC (0.173", 4.40 mm width) Mini-Flat package, the FODM453R2V is surface-mount compatible with standard SOIC-6 footprints — the missing pin 6 position is a moulded key, not a missing lead, so confirm the land pattern against the onsemi package drawing before layout.

No stock-holding claim; we source to order.

Frequently asked questions

Is FODM453R2V RoHS compliant?

Yes, the part is ROHS3 compliant per onsemi's listing.

What is the closest pin-compatible alternative to FODM453R2V?

Within the same 5-lead Mini-Flat package, other onsemi optoisolators with similar 3750Vrms isolation and transistor output exist, but pin compatibility depends on the CTR grade and switching speed required — verify the land pattern and output voltage rating before substituting.
