MOC3063S-TA1

Triac, SCR Output Optoisolators Overview

The MOC3063S-TA1 is a Triac and SCR output optocoupler manufactured by Lite-On Inc. It features a single channel with an integrated zero-crossing circuit for low electromagnetic interference switching. The device utilizes a PhotoTriac output capable of blocking up to 600 V in the off-state. Electrical specifications include a maximum forward current of 50 mA, a forward voltage of 1.2 V, and a power dissipation rating of 250 mW. The component provides 5000 Vrms isolation voltage between input and output. It operates within a temperature range of -40°C to +100°C and is housed in a 6-SMD Gull Wing package.

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix TA1 corresponds to the tape-and-reel surface mount configuration rather than the through-hole PDIP variant. Confirm RoHS compliance status and check for any recent product change notices regarding pinout or thermal characteristics before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing functionality is required to minimize switching transients in AC loads. Ensure the system voltage does not exceed the 600 V blocking limit. Consider the 5000 Vrms isolation rating for safety requirements. Verify that the surface mount footprint matches the PCB layout constraints.
