Overview
The onsemi FOD814AW is a transistor output optocoupler featuring an NPN phototransistor. It provides 5000 Vrms insulation voltage and supports through-hole mounting in a PDIP-4 package. The device operates with a forward current of up to 50 mA and a forward voltage of 1.4 V. It handles a maximum collector-emitter voltage of 70 V and a collector current of 50 mA. The unit weight is 260 mg, and it functions within a temperature range of -55°C to +105°C.
Feature Summary
- Provides high-voltage isolation via 5000 Vrms dielectric strength between input and output circuits.
- Utilizes an NPN phototransistor output for reliable signal transmission.
- Designed for through-hole installation in standard PDIP-4 packages.
Applications
- General-purpose digital signal isolation
- Microprocessor system interfacing
- Solid-state relay driver circuits
Procurement Notes
Verify the obsolete status of the FOD814AW before procurement planning. Confirm availability of parametric equivalents such as the FOD814A300W. Ensure that any substitute component matches the required DIP-4 footprint and electrical specifications to maintain circuit integrity without redesign.
Selection Notes
Select this component for applications requiring robust galvanic isolation in through-hole designs. Consider the specific switching speed requirements against the device's rise and fall times. Evaluate thermal management needs given the power dissipation limits and operating temperature range specified in the datasheet.
Part Context
The FOD814AW belongs to the FOD814A series of transistor output optocouplers from onsemi. This series is designed for general-purpose isolation tasks. The AW suffix typically denotes a specific packaging or tape-and-reel configuration variant within the broader product line, distinct from the tube-packaged FOD814A300.
Replacement Considerations
The FOD814A300W is listed as a parametric equivalent substitute. Verify pinout compatibility and package dimensions when transitioning from the obsolete FOD814AW to ensure mechanical fit in existing assemblies.
