It provides 3750Vrms galvanic isolation between input and output, with each of the four independent channels rated for 80V output and 50mA continuous current. ## CTR window and switching speed The current transfer ratio (CTR) is specified between 50% and 600% at a forward current of 500µA. That 50% minimum guarantees the output transistor will saturate with a modest LED drive, while the 600% ceiling gives headroom for degraded LED output over temperature or lifetime. Typical rise and fall times are 2µs and 3µs respectively, and turn-on/turn-off times are both 3µs — fast enough for 100 kbps isolated data links or low-speed relay replacement. ## Active lifecycle — no LTB concern It is RoHS compliant. ## Tube packaging — design-in note This variant ships in Tube (not Tape & Reel), which is the typical procurement format for prototype or low-volume builds. If your pick-and-place line requires reeled parts, the sibling order code TLP293-4(LA-TR,E is the Tape & Reel version with identical electrical specifications. The 16-SOIC footprint (4.55mm body width) is a common optocoupler package; layout guidelines for 3750Vrms isolation clearance should follow the creepage and clearance rules in the datasheet.","metaTitle":"TLP293-4(LA,E Toshiba Quad Optocoupler, 3750Vrms, 16-SOIC","metaDescription":"Toshiba TLP293-4(LA,E quad transistor-output optocoupler, 3750Vrms isolation, 50-600% CTR at 500µA, -55°C to 125°C, 16-SOIC.
