PC3SD12NTZA

Triac, SCR Output Optoisolators Overview

The PC3SD12NTZA is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It provides electrical isolation with a rated insulation voltage of 5000Vrms. The device features a non-zero-crossing triac output capable of handling a maximum RMS on-state current of 100 mA and a peak off-state voltage of 600 V. Key electrical parameters include a typical forward voltage of 1.2 V, a maximum DC forward current of 50 mA, and a maximum turn-on time of 50 µs. It operates within a temperature range of -30°C to 100°C and is housed in a 6-DIP package.

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity as the PC3SD12NTZA is officially obsolete and no longer manufactured. Confirm that any available units are genuine Sharp Microelectronics products rather than refurbished or counterfeit items. Check datasheet revisions to ensure compatibility with original design specifications before procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component only if legacy compatibility is required, as it has been superseded by newer series. Ensure the circuit design accommodates the non-zero-crossing output behavior, which may cause noise at AC zero crossings. Verify that the 600 V blocking voltage and 100 mA current ratings meet the specific load requirements of the application.

Triac, SCR Output Optoisolators Part Context

This part belongs to the Sharp PC3SD series of phototriac optocouplers. It serves as an isolation interface for controlling AC power devices. The series is characterized by its robust insulation capabilities and compact DIP packaging, widely used in older industrial and consumer electronics designs requiring reliable triac triggering signals.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers include MOC3052M and APT1222. These alternatives offer similar functionality but require verification of pinout compatibility and electrical parameter alignment with the original design constraints.
