PC3SD21NTZC

Triac, SCR Output Optoisolators Overview

The PC3SD21NTZC is a single-channel phototriac output optocoupler manufactured by Sharp Microelectronics. It features an internal zero-crossing detection circuit to minimize electromagnetic interference during switching. The device provides high isolation with a rated insulation voltage of 5000 Vrms. It operates within a temperature range of -30°C to +100°C and is housed in a standard 6-pin DIP package suitable for through-hole mounting.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry for low-noise AC power control
• High-voltage electrical isolation between input and output sections
• Robust triac output stage designed for direct AC load interfacing

Triac, SCR Output Optoisolators Applications

• Solid-state relays (SSRs)
• AC motor speed controllers
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status, as suffixes often denote packaging or material variations. Confirm availability directly with Sharp Microelectronics or authorized distributors, as lead times may vary based on production schedules.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC applications. Ensure the load current does not exceed the device's RMS current rating. Verify that the system voltage remains within the peak repetitive off-state voltage limits specified in the official electrical characteristics table.

Triac, SCR Output Optoisolators Part Context

This part belongs to Sharp's PC3S series of phototriac optocouplers. The series is characterized by integrated zero-crossing circuits, distinguishing it from non-zero-crossing variants like the PC3SD11 series. These devices are widely used in industrial automation and consumer electronics requiring safe isolation for AC switching.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with PC3SD21NTZAH for identical functional specifications but potential differences in tape-and-reel packaging versus tube packaging. Verify mechanical dimensions and pin configurations before substitution.
