Overview
The PC123AJ0000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output and operates with a DC input. The device provides high isolation capability with an insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 50 mA, and a typical forward voltage of 1.4 V. The unit is housed in a 4-pin DIP package and supports surface mount installation styles.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED and phototransistor technology.
- Features a robust dielectric barrier capable of withstanding high voltage stress for safety applications.
- Utilizes a standard four-lead dual in-line package design for straightforward circuit integration.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix J0000F against official Sharp datasheets to confirm pinout and electrical ratings. Confirm RoHS compliance status through manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability records for this discontinued or legacy component series.
Selection Notes
Select this component when high isolation voltage is required in a compact DIP format. Compare the 5000 Vrms rating against system safety standards. Evaluate the 80 V collector-emitter voltage limit against load requirements. Consider the 50 mA forward current capacity for drive circuit design.
Part Context
This part belongs to Sharp's PC123 series of transistor output optocouplers. The series is designed for general-purpose isolation tasks. The PC123AJ variant specifically denotes the 5000 Vrms insulation class within the lineup. It serves as a legacy solution for older industrial designs requiring verified isolation barriers.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult Sharp Microelectronics for current equivalent recommendations or updated series replacements.
