TLP266J(V4-TPL,E

Triac, SCR Output Optoisolators Overview

The TLP266J(V4-TPL,E) is a phototriac output optocoupler featuring an integrated zero-crossing detection circuit. It provides electrical isolation between input and output sides with a rated insulation voltage of 3750 Vrms. The device utilizes a gallium arsenide infrared LED as the light source and a photo-triac for signal transmission. Key electrical parameters include a maximum forward current of 20 mA, a peak off-state voltage (VDRM) of 600 V, and a maximum trigger current of 10 mA. The component supports surface mount installation in a 6-SOP package.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TPL' corresponds to the tape and reel packaging configuration when ordering. Confirm that the required isolation voltage and peak off-state voltage meet the target application's safety standards. Ensure compatibility with the intended PCB footprint for the 6-SOP package. Cross-reference the manufacturer datasheet for any updates on recommended soldering profiles or storage conditions prior to procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize electromagnetic interference and inrush currents in AC circuits. Compare against non-zero-crossing variants if phase-angle control is necessary instead. Evaluate the 600 V peak off-state voltage against the maximum line voltage of the application. Consider the thermal dissipation requirements based on the specified power dissipation limits in the operating environment.
