Overview
The FOD817300 is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and is housed in a 4-pin MDIP package for through-hole mounting. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum continuous collector current of 50 mA, and a forward current of 50 mA. The typical rise and fall times are 18 µs. The unit operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for digital or analog signal transmission
- Designed for surface mount or through-hole integration via standard DIP packaging
Applications
- General-purpose signal isolation in industrial control systems
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits requiring galvanic separation
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure that the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with the latest product change notices to confirm manufacturing status and material declarations before finalizing orders.
Selection Notes
Select this component when a robust, general-purpose optocoupler with high isolation voltage is required. The NPN phototransistor output suits applications needing moderate switching speeds. Consider thermal management requirements given the operating temperature range. Verify that the forward current limits align with the driving circuit capabilities to ensure reliable operation over the specified lifetime.
Part Context
This component belongs to the FOD817 series of optocouplers from onsemi. The series is widely recognized for its reliability in isolation applications. The FOD817300 variant specifically denotes the transistor output type in a 4-pin MDIP package. This family serves as a standard solution for basic isolation needs across various electronic industries.
Replacement Considerations
Compatible substitutes include other FOD817 series variants such as FOD817D or FOD817C, provided the package and electrical characteristics match the design requirements. Verify pin compatibility and isolation ratings when substituting.
