It delivers 2500Vrms of galvanic isolation between the DC input and the transistor output, which is the baseline for basic isolation in industrial and power-supply applications. The current transfer ratio (CTR) is specified at 130% minimum to 260% maximum when driven with 1 mA forward current — a tighter bin than the broad commercial range, which reduces the spread in collector current across a reel and simplifies the bias resistor calculation in the receiver circuit. ## What the switching speed means for your design Rise and fall times are 6 µs and 7 µs typical respectively, with turn-on and turn-off times both at 6 µs typical. This places the FOD8802BR2 in the medium-speed class — adequate for 50/60 Hz line synchronisation, DC-link voltage sensing, and general-purpose logic isolation where the signal rate stays below ~10 kHz. It is not intended for high-speed digital isolation; a digital isolator or high-speed optocoupler would be needed above that bandwidth. The 75 V output rating and 30 mA continuous output current per channel cover most low-side switch and PLC digital input interfaces. The 400 mV maximum Vce saturation at the rated current keeps the voltage drop low enough to drive a 5 V logic input without an additional level shift. ## Temperature grade and operating range The CTR is specified at 1 mA drive across this range, so the minimum gain at the hot end is the figure to budget for worst-case collector current.","metaTitle":"onsemi FOD8802BR2 OptoHit™ Optoisolator, 2500Vrms, 2-Ch","metaDescription":"onsemi FOD8802BR2 dual-channel transistor-output optocoupler, 2500Vrms isolation, 130-260% CTR at 1mA, -40 to +125°C.
