The 5000Vrms isolation rating suits it for galvanic isolation in power supplies, motor drives, and industrial interface circuits where the primary-to-secondary barrier must withstand high potential differences. The current transfer ratio is specified between 200% and 400% at a 5mA forward current, giving the designer a predictable gain window for driving logic inputs or low-current loads. ## Temperature range and output drive The output transistor can handle up to 80V and 50mA per channel, which is enough to switch a small relay, a PLC input, or a MOSFET gate through a pull-up resistor. Typical turn-on and turn-off times are both 3µs, with rise and fall times of 2µs and 3µs respectively — fast enough for 100 kHz switching or for debouncing isolated signals. RoHS compliance is confirmed, which simplifies the BOM for EU-market equipment and avoids a separate waiver process.","metaTitle":"TLP385(BLL-TPL,E Transistor Optocoupler, 5000Vrms, 4-Pin SO","metaDescription":"TLP385(BLL-TPL,E transistor optocoupler, 1-channel DC input, 5000Vrms isolation, 200-400% CTR at 5mA, -55 to 110°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"6-SOIC (0.173\\\", 4.40mm Width), 4 Leads","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)":"2µs, 3µs","Voltage - Output (Max)":"80V","Supplier Device Package":"6-SO, 4 Lead","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"400% @ 5mA","Current Transfer Ratio (Min)":"200% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.25V","Turn On / Turn Off Time (Typ)":"3µs, 3µs","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.54000","currency":"USD"},{"qty":10,"price":"$0.35500","currency":"USD"},{"qty":100,"price":"$0.23450","currency":"USD"},{"qty":1000,"price":"$0.18107","currency":"USD"},{"qty":3000,"price":"$0.16362","currency":"USD"},{"qty":6000,"price":"$0.15271","currency":"USD"},{"qty":15000,"price":"$0.14726","currency":"USD"},{"qty":30000,"price":"$0.14508","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/331d269fb9551bcaaac5f6b0e0ad3456.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TLP385(BLL-TPL,E have a 4-pin SO package?","answer":"The package is a 6-SOIC body (0.173\", 4.40mm width) with only 4 leads populated, so it is physically a 6-pin SOIC outline but electrically a 4-pin device."},{"question":"What is the difference between TLP385(BLL-TPL,E and standard TLP385?","answer":"The TLP385(BLL-TPL,E is a specific CTR-binned variant within the TLP385 family, with a guaranteed CTR range of 200% to 400% at 5mA.
