MOC8105

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8105 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features an infrared LED emitter coupled to a phototransistor output, housed in a 6-DIP package. The device provides high isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum output voltage of 30V, typical forward voltage of 1.25V, and maximum collector-emitter saturation voltage of 400mV. The component is RoHS compliant and currently marked as obsolete.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates an infrared LED with a phototransistor for signal transmission across isolated barriers
• Provides robust electrical isolation via a 5300Vrms dielectric barrier
• Designed for compact integration within standard dual-in-line packaging configurations

Transistor, Photovoltaic Output Optoisolators Applications

• General purpose signal isolation in industrial control systems
• Interface circuits requiring galvanic separation between logic levels

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through official Vishay channels due to obsolete status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Check for alternative sourcing options from authorized distributors holding remaining stock. Ensure storage conditions maintain component integrity prior to assembly.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Evaluate the 30V output voltage limit against circuit load requirements. Consider the 5300Vrms isolation rating for safety compliance needs. Assess the 6-DIP package dimensions for PCB layout compatibility. Review turn-on characteristics if speed is critical for the intended application timing.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to Vishay's MOC series of transistor-output optoisolators. It shares functional similarities with other models in the family but differs in pinout and specific electrical ratings. The series is designed for general-purpose isolation tasks where moderate speed and high voltage tolerance are required.
