It accepts both AC and DC input on the LED side, which makes it useful for sensing line-voltage zero-crossing or detecting relay states in industrial controls, motor drives, and power-supply feedback loops. The 3750Vrms isolation rating provides a basic safety barrier for reinforced insulation in mains-connected equipment. The 3750Vrms isolation voltage is the primary safety spec — it determines whether this part meets the creepage and clearance requirements for a given mains-voltage class. For a 240VAC application, 3750Vrms is typical for basic isolation; if reinforced isolation is needed, you may need a higher-rated device. The current transfer ratio (CTR) is specified as 100% minimum and 600% maximum at 5mA forward current. That wide window means the output transistor can saturate with a modest LED drive, but the gain variation across units must be accounted for in the pull-up resistor and noise margin. A 10kΩ collector load with 5mA input gives a solid logic-level output across the full CTR range. The 80V output breakdown and 50mA continuous output current handle typical 24V PLC inputs and low-power relay drivers without extra buffering. Rise and fall times are 2µs and 3µs typical, which limits the switching speed to about 100 kHz — fine for 50/60 Hz line sensing, relay feedback, and isolated serial data at 9600 baud, but not for high-speed digital isolation. ## Package and footprint The supplier device package is 4-SO. The surface-mount body is suitable for automated assembly and reflow soldering.","metaTitle":"TLP292(GB-TPL,E Optoisolator, 3750Vrms, Transistor Output","metaDescription":"TLP292(GB-TPL,E optoisolator from Toshiba: 3750Vrms isolation, transistor output, AC/DC input, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"AC, DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"4-SOIC (0.179\\\", 4.55mm Width)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"3750Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C ~ 125°C","Rise / Fall Time (Typ)":"2µs, 3µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-SO","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"600% @ 5mA","Current Transfer Ratio (Min)":"100% @ 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":"$0.55","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.55000","currency":"USD"},{"qty":10,"price":"$0.36100","currency":"USD"},{"qty":100,"price":"$0.23890","currency":"USD"},{"qty":1000,"price":"$0.18443","currency":"USD"},{"qty":2500,"price":"$0.16665","currency":"USD"},{"qty":5000,"price":"$0.15554","currency":"USD"},{"qty":12500,"price":"$0.14998","currency":"USD"},{"qty":25000,"price":"$0.14776","currency":"USD"},{"qty":62500,"price":"$0.14165","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b7869854d6daec776357c5d44ac6eb68.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between TLP292 and TLP293?","answer":"The TLP293 is a higher-CTR variant often used for lower LED drive current. The TLP292(GB-TPL,E has a CTR range of 100% to 600% at 5mA, while the TLP293 typically offers a higher minimum CTR.
