That isolation voltage is the deciding spec for applications where you need a reinforced barrier — think motor-drive feedback, PLC digital inputs, or medical patient-interface circuits where a fault on the high-voltage side must not reach the low-voltage control logic. The 6-DIP through-hole package (0.400\" pin spacing) gives you the creepage distance to support that rating in real PCB layouts without slotting the board. ## CTR range and switching speed — what to expect at the bench Current transfer ratio spans 63% to 125% at 10 mA forward current. Vce saturation maximum is 300 mV. ## Temperature range and operating environment Rated from -55°C to 110°C. Input type is DC.","metaTitle":"TCDT1102G Optocoupler, 5000Vrms Isolation, 6-DIP","metaDescription":"TCDT1102G optocoupler with 5000Vrms isolation, 63-125% CTR, transistor output, -55°C to 110°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.400\\\", 10.16mm)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"7µs, 6.7µs","Voltage - Output (Max)":"32V","Supplier Device Package":"6-DIP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"125% @ 10mA","Current Transfer Ratio (Min)":"63% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.25V","Turn On / Turn Off Time (Typ)":"11µs, 7µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.67","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.68000","currency":"USD"},{"qty":10,"price":"$0.44900","currency":"USD"},{"qty":100,"price":"$0.29670","currency":"USD"},{"qty":1000,"price":"$0.22911","currency":"USD"},{"qty":2000,"price":"$0.20703","currency":"USD"},{"qty":5000,"price":"$0.19323","currency":"USD"},{"qty":10000,"price":"$0.18633","currency":"USD"},{"qty":25000,"price":"$0.18357","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6c0ec0f7f9c4caa221569b49dd07a3b2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) of TCDT1102G?","answer":"CTR is specified as 63% minimum and 125% maximum, both measured at 10 mA forward current.
