Overview
The PC12311NSZ1B is a transistor output optoisolator manufactured by SHARP/Socle Technology. It features a single channel with 5000Vrms isolation voltage and operates within a temperature range of -25°C to 100°C. The device utilizes a 4-DIP package for through-hole mounting. Key electrical specifications include a maximum collector current of 50mA, a maximum output voltage of 80V, and a typical forward voltage of 1.2V. Response times are characterized by rise and fall times of 4µs and 3µs respectively.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical transmission.
- Features a transistor output configuration suitable for digital signal switching applications.
- Designed for through-hole PCB mounting in a compact 4-DIP package.
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix NSZ1B against official datasheets to confirm pinout and isolation ratings. Confirm RoHS compliance status as manufacturing processes may evolve. Check for obsolescence notices from the manufacturer or authorized distributors before finalizing design-in decisions.
Selection Notes
Select this component when high isolation voltage is required in a small form factor. Ensure the application demands a transistor output rather than an AC or logic gate output. Verify that the 50mA collector current rating meets the load requirements of the target circuit.
Part Context
This part belongs to the SHARP/Socle Technology optoisolator family, which offers various isolation voltages and output types. The PC12311 series specifically targets applications needing robust electrical isolation in standard DIP packages, distinguishing it from surface-mount alternatives like the PC3H7 series.
Replacement Considerations
Consult official substitution guides for equivalent parts with matching isolation voltage and package dimensions. Generic replacements must maintain the 5000Vrms rating and 4-DIP footprint to ensure mechanical compatibility.
