Product Description
The onsemi FOD3120 is a high-performance optocoupler designed for electrical isolation and signal transmission between high voltage and low voltage circuits. Packaged in a compact 8-pin PDIP through-hole format, this component suits industrial, power electronics, and control system applications requiring reliable isolation and fast response times.
Featuring a maximum forward voltage of 1.8V and maximum input current of 16mA, the FOD3120 provides high noise immunity with a minimum common mode rejection of 35kV per microsecond, ensuring stable operation in electrically noisy environments. The output stage utilizes P-channel MOSFET technology, allowing output voltage swings close to the supply rail within a wide voltage range of 15V to 30V.
The device supports peak output current up to 2.5A, making it capable of driving power devices such as 800V/20A IGBTs. Fast switching characteristics with typical rise and fall times of 60ns and a maximum propagation delay of 400ns enhance its suitability for high-speed switching circuits.
The FOD3120 offers an isolation voltage rating of 5kVrms for one minute, compliant with DIN EN/IEC60747-5-5 and UL1577 certifications to ensure safety and reliability in electrical isolation applications. Operating temperature ranges from -40°C to 100°C allow usage in harsh industrial and automotive environments where temperature variability is significant.
This optocoupler is widely used in power supplies, motor control, industrial automation, HVAC systems, and other electronic devices requiring robust isolation and signal integrity. The through-hole 8-pin PDIP package facilitates easy PCB mounting and prototyping.
High noise immunity characterized by 35kV/μs minimum common mode rejection. 2.5A peak output current capability driving most 800V/20A IGBTs. Use of P-channel MOSFETs at output stage enables output voltage swing close to supply rail.
Wide supply voltage range from 15V to 30V. Fast switching speed with 400ns maximum propagation delay and 60ns typical rise/fall times. Isolation voltage 5kVrms for 1 minute. Compliance with DIN EN/IEC60747-5-5 and UL1577 safety standards.
Operating temperature from -40°C to 100°C. 8-pin PDIP through-hole package. Explore more on Optocouplers and related electronic components in EnvMart's comprehensive catalog, ensuring reliable industrial and power electronics design solutions.
