Overview
The PC957L0NSZ is a high-speed, high common-mode rejection ratio (CMR) linear output photocoupler manufactured by Sharp Microelectronics. It integrates an infrared LED and a phototransistor in an 8-DIP package to provide electrical isolation between input and output circuits. Key electrical specifications include a maximum collector-emitter voltage of 20 V, a typical forward voltage of 1.7 V, and a maximum DC forward current of 25 mA. The device supports a minimum current transfer ratio of 19% at 16 mA and features turn-on/turn-off times of 200 ns and 400 ns respectively. It operates within a temperature range of -55°C to +85°C.
Feature Summary
- High common-mode rejection ratio for noise immunity
- Linear output characteristic for signal transmission
- High-speed switching capability with nanosecond response times
Applications
- Digital logic signal transmission and conversion
- Power supply control and switching circuits
- Electrical insulation isolation between circuits and systems
- Impedance transformation applications
Procurement Notes
Verify the specific suffix NSZ corresponds to the 8-DIP package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required thermal operating range for the intended application environment.
Selection Notes
Select this component when high-speed data transmission with high noise immunity is required. The linear output type distinguishes it from standard digital optocouplers, making it suitable for analog signal isolation. Verify that the 20 V output voltage rating and 8 mA output current capacity align with the load requirements of the receiving circuitry.
Part Context
This part belongs to the Sharp PC957L series of high-speed photocouplers. It is designed to replace older generation optocouplers in applications demanding faster response times and better interference rejection. The series utilizes OPIC technology to achieve high performance in a compact DIP package.
Replacement Considerations
Direct replacements must match the 8-DIP package, 5000 Vrms isolation voltage, and similar speed characteristics. Verify pinout compatibility and ensure the substitute component offers comparable current transfer ratio and propagation delay specifications.
