What are the key features of MOC8102-X017?
- 5300 V isolation voltage providing safe galvanic separation between input and output circuits in AC line-powered equipment
- Current transfer ratio (CTR) of 73-117% at 10 mA forward current, delivering predictable phototransistor drive for digital logic interface circuits
- Surface mount small-outline package with UL approval enabling compact PCB integration and regulatory compliance in consumer and industrial equipment
What is MOC8102-X017 used for?
The MOC8102-X017 is used to isolate control logic from high-voltage power circuits in switching power supplies, motor drives, and industrial relay drivers where 5300 V galvanic isolation is required. Its phototransistor output and 73% minimum CTR make it well suited for AC line voltage detection and feedback isolation in UPS systems and home appliance controls. The surface mount package streamlines SMT production of safety-rated boards in medical device power supplies and HVAC controller modules.

Frequently Asked Questions
What isolation voltage does the MOC8102-X017 provide and why is it important for mains-connected applications?
The MOC8102-X017 provides a 5300 V RMS isolation voltage between the LED input and phototransistor output, exceeding the 4000 V requirement of many IEC 60950-1 and IEC 62368-1 safety standards. This level of galvanic isolation protects low-voltage control circuits from AC mains transients and ensures user safety in equipment connected to 100 V to 240 V supply lines.
How does the CTR range of 73-117% on the MOC8102-X017 affect circuit design compared to higher-CTR optocouplers?
A CTR of 73-117% at 10 mA forward current means the output collector current is approximately 0.73 to 1.17 times the input LED current. Designers should size the output pull-up resistor to ensure the phototransistor enters saturation under worst-case CTR of 73%, which typically requires a pull-up of less than 10 kohm from a 5 V rail when driving 3.3 V logic threshold inputs.
Can the MOC8102-X017 replace the MOC8101 or MOC8103 in existing designs, and what changes are needed?
The MOC8102-X017 fits the same SMT footprint as the MOC8101 and MOC8103 variants, which share the same 30 V collector-emitter breakdown voltage and 60 mA maximum forward current. The key difference is CTR: MOC8101 has a CTR of 10-50%, MOC8102 is 73-117%, and MOC8103 is above 100%. Swapping to MOC8102 from MOC8101 requires recalculating the output pull-up resistor to avoid over-driving the load transistor at the higher CTR.
