What are the key features of MOC8102?

5300 V isolation voltage providing robust galvanic separation between input and output circuits in industrial and safety-critical designs
73% typical current transfer ratio (CTR) at 60 mA forward current enabling efficient signal coupling with minimal drive current
30 V collector-emitter breakdown voltage with 50 nA maximum dark current for clean, low-leakage switching performance
DIP-6 through-hole package with RoHS-compliant, e3 JEDEC moisture classification for lead-free manufacturing compatibility

What is MOC8102 used for?

The Vishay MOC8102 optocoupler is used in industrial motor drives, switched-mode power supply (SMPS) feedback loops, and programmable logic controller (PLC) I/O interfaces where 5300 V galvanic isolation between high-voltage and logic-level circuits is required. Its single-channel phototransistor configuration suits microcontroller-driven relay and triac gate control circuits that demand reliable signal transfer across isolation barriers. The DIP-6 package makes it straightforward to integrate into through-hole prototyping boards and production control panels.

Frequently Asked Questions

How much isolation voltage does the MOC8102 provide, and is that sufficient for mains-connected equipment?

The MOC8102 offers a maximum isolation voltage of 5300 V, which exceeds the 2500 V minimum typically required for mains-connected equipment isolation in many safety standards. This makes it suitable for use in AC line-powered SMPS feedback circuits and industrial interface boards where regulatory isolation barriers between the mains and low-voltage control sides are mandatory.

What is the current transfer ratio of the MOC8102 and how does it affect LED drive current requirements?

The MOC8102 has a nominal current transfer ratio (CTR) of 73% at up to 60 mA forward current. This means that to achieve a 10 mA collector output current, approximately 14 mA of LED forward current is required, allowing designers to use low-current microcontroller GPIO pins with a simple current-limiting resistor rather than a buffer transistor stage.

Can the MOC8102 be used as a direct replacement for MOC8101 or MOC8103 in existing designs?

The MOC8102 shares the same DIP-6 footprint and 5300 V isolation rating with the MOC8101 and MOC8103, differing mainly in current transfer ratio range. The MOC8101 has a lower CTR minimum while MOC8103 has a higher CTR minimum. If your circuit tolerates the 73% CTR of the MOC8102, substitution is straightforward with no PCB changes, though recalculating the input resistor value is recommended to confirm proper output switching at the 30 V collector-emitter limit.
