It provides 3750Vrms of galvanic isolation between the input LED and the output phototransistor, with a minimum current transfer ratio of 100% and a maximum of 600% at a forward current of 5mA. The output transistor can handle up to 80V and 50mA, with a Vce saturation of 300mV. The 3750Vrms isolation rating is the primary spec that determines whether this part can safely separate a high-voltage primary side from a low-voltage control side in a switched-mode power supply, motor drive, or industrial interface. The 50mA output current ceiling limits the load to a small relay coil, a logic gate input, or a status LED — anything heavier needs a driver transistor after the opto. The 100% to 600% CTR range at 5mA gives the designer a wide margin to account for LED degradation over temperature and time; a CTR at the low end still guarantees the output saturates with the right bias resistor. ## Switching speed and timing Rise and fall times are 2µs and 3µs; turn-on and turn-off times are both 3µs. ## Package and footprint considerations The package (0.179\" body width, 4.55mm) is a standard small-outline footprint common to many Toshiba and competitor optocouplers. The surface-mount form factor suits automated assembly, and the package is compatible with reflow soldering. The tape-and-reel and cut-tape options cover both prototyping and volume production.","metaTitle":"Toshiba TLP293(GB-TPL,E Optocoupler, 3750Vrms, 1-Ch DC Input","metaDescription":"Toshiba TLP293(GB-TPL,E single-channel transistor-output optocoupler. 3750Vrms isolation, 50mA output, 100-600% CTR at 5mA, -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":"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":"$0.5","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.50000","currency":"USD"},{"qty":10,"price":"$0.32800","currency":"USD"},{"qty":100,"price":"$0.21720","currency":"USD"},{"qty":1000,"price":"$0.16766","currency":"USD"},{"qty":2500,"price":"$0.15150","currency":"USD"},{"qty":5000,"price":"$0.14140","currency":"USD"},{"qty":12500,"price":"$0.13635","currency":"USD"},{"qty":25000,"price":"$0.13433","currency":"USD"},{"qty":62500,"price":"$0.12878","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b95b5eb516f49787d0f52ba5dc00946c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the exact specifications of TLP293(GB-TPL,E (CTR, isolation, Vce)?","answer":"The key specs are: isolation voltage 3750Vrms, current transfer ratio 100% to 600% at 5mA, output transistor Vce max 80V, output current per channel 50mA, Vce saturation 300mV, forward voltage 1.25V typical, rise/fall times 2µs/3µs, operating temperature -55°C to 125°C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP293GB-TPLE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP293GB-TPLE when reusing this data.
