The -55°C to 110°C operating range (cite:) keeps it functional in outdoor telecom cabinets and engine-bay environments where commercial-grade optos (0°C to 70°C) would drift out of spec. Unlike many phototransistor optos that only accept DC forward current, the FODM214's AC/DC input (cite:) lets it sense AC line zero-cross directly — no external bridge rectifier needed, saving two diodes and a filter cap on the primary side. ## CTR spread and switching speed — the design-in tradeoffs Current transfer ratio spans 20% to 400% at 1 mA forward current (cite:,). That wide spread means the designer must size the pull-up resistor for the minimum CTR at the actual LED current to guarantee the output transistor saturates — at 1 mA If, a 20% CTR delivers only 0.2 mA to the load, which may not drive a logic input without a high-value pull-up. Typical rise and fall times are both 3 µs (cite:), with matching turn-on and turn-off times (cite:). This 3 µs edge rate limits the part to switching frequencies below roughly 50 kHz — fine for relay drivers, PLC inputs, and isolated serial interfaces, but not for high-speed isolated SPI or gate-drive feedback. ## Sourcing and lifecycle — active, no end-of-life watch onsemi lists the FODM214 as Active (cite:) with ROHS3 compliance (cite:). Sourced per RFQ against the BOM quantity — no stock-holding claim, confirmed at quote time. The 4-SOP package (cite:) is the standard SOIC-4 footprint used across the FODM214 series, so a layout designed for this part can also accept the FODM217BR2V (cite:) or FODM217A (cite:) if supply tightens — both are DC-input only, so the AC/DC capability is lost in a swap.","metaTitle":"FODM214 onsemi 3750Vrms AC/DC Input Transistor Output","metaDescription":"onsemi FODM214 phototransistor optocoupler, 3750Vrms isolation, AC/DC input, 4-SOP package.
