It delivers a current transfer ratio between 150% and 300% at a forward current of 5 mA. The output transistor is rated for 80 V maximum and 50 mA continuous current. ## Temperature range and switching speed Operating temperature spans -55°C to 110°C. Rise and fall times are 2 µs and 3 µs typical, with turn-on and turn-off both at 3 µs. ## Package and mounting for the assembly line Housed in a 4-SOIC package with 0.179-inch (4.55 mm) body width. The supplier device package is 4-SO. Check the MSL rating before reflow — Toshiba optocouplers in this family typically carry MSL 1, but verify the reel date code to avoid popcorning.","metaTitle":"TLP291(GRH,SE Toshiba Optocoupler 3750Vrms 4-SOIC Active","metaDescription":"TLP291(GRH,SE Toshiba transistor-output optocoupler, 1 channel, 3750Vrms isolation, 150-300% CTR at 5mA, -55 to 110°C, 4-SOIC.","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":"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 ~ 110°C","Rise / Fall Time (Typ)":"2µs, 3µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-SO","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"300% @ 5mA","Current Transfer Ratio (Min)":"150% @ 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":"$0.59","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.59000","currency":"USD"},{"qty":10,"price":"$0.36400","currency":"USD"},{"qty":100,"price":"$0.20910","currency":"USD"},{"qty":1000,"price":"$0.16362","currency":"USD"},{"qty":2000,"price":"$0.14999","currency":"USD"},{"qty":5000,"price":"$0.13635","currency":"USD"},{"qty":10000,"price":"$0.12726","currency":"USD"},{"qty":25000,"price":"$0.12272","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a8ee6f0a66b20e745d1c9a7a3ea4ce22.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TLP291(GRH,SE a direct replacement for TLP291?","answer":"The TLP291(GRH,SE is a specific CTR-binned variant of the TLP291 family.
