Overview
The PC851XNNIP0F is a single-channel transistor output optoisolator manufactured by Sharp Microelectronics. It features a high isolation voltage of 5000Vrms and supports a maximum collector-emitter voltage of 350V. The device operates with a DC input and provides a typical forward voltage of 1.2V at a maximum forward current of 50mA. Key electrical parameters include a minimum DC current transfer ratio of 40% at 5mA, a saturation voltage of 300mV, and rise/fall times of 4µs and 5µs respectively. It is housed in a 4-SMD鸥翼 package and functions within a temperature range of -25°C to 100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using a phototransistor configuration.
- Offers robust performance with a low saturation voltage for efficient switching applications.
- Designed for surface-mount installation in compact electronic assemblies.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify component authenticity through authorized channels as this part is marked obsolete. Confirm package integrity upon receipt since it ships in tape and reel format. Check datasheet revisions for any parameter updates before final design integration. Ensure handling procedures comply with ESD safety standards for surface-mount devices.
Selection Notes
Select this component when high voltage isolation and fast switching speeds are required in a small footprint. Compare the 40% CTR specification against circuit requirements to ensure adequate signal transfer. Consider the 350V output rating for compatibility with load voltages. Evaluate thermal management needs given the operating temperature range limits.
Part Context
This device belongs to Sharp's PC851 series of high-voltage optocouplers. It utilizes a gallium arsenide infrared LED coupled to an NPN silicon phototransistor. The series is known for reliability in industrial environments. The specific suffix indicates the packaging and compliance status defined by the manufacturer.
Replacement Considerations
Public confirmed substitute part numbers: None identified in available documentation. Verify cross-reference data from official Sharp Microelectronics resources before substitution.
