MOC8108X

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8108X is a single-channel phototransistor optocoupler manufactured by Isocom Components. It integrates an infrared emitting diode and an NPN silicon phototransistor in a standard 6-pin dual in-line plastic package with the base pin unconnected. The device provides high isolation voltage of 5300Vrms, ensuring robust signal transmission between isolated circuits. It operates within a temperature range of -55°C to 100°C and features typical rise and fall times of 2µs. The component is RoHS compliant and approved under UL, VDE, and CECC standards.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'X' against the manufacturer's current datasheet to confirm lead frame plating and compliance status. Ensure the ordering part number matches the required package variant (STD, G form, or SMD) as defined in official documentation. Cross-reference approval certificates such as UL File No. E91231 and VDE 0884 for regulatory requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a non-base-connected phototransistor output is required for simple switching applications. Consider the 5300Vrms isolation rating for safety-critical designs. Evaluate the CTR specifications at the intended forward current to ensure adequate signal transfer. Confirm that the 6-DIP package fits the available PCB space and assembly constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

The MOC8108X belongs to the MOC810x series of phototransistor optocouplers, which are widely used in power supply and industrial control applications. This series shares common characteristics with related models like MOC8106X and MOC8107X, differing primarily in current transfer ratio ranges. The 'X' suffix typically denotes specific manufacturing or compliance variations within the Isocom portfolio.
