The current transfer ratio (CTR) spans 200% to 400% at a forward current of 5mA, which means the output transistor can sink at least twice the input current across the full temperature range. That gain margin is what lets you drive a 5V logic input with a 5mA LED current and still have headroom for CTR degradation over life. ## Lifecycle and supply posture Toshiba lists the TLP385(BLL-TPR,E as Active with RoHS compliance. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options, surface-mount in a 6-SO, 4-lead package.

With a typical Vf of 1.25V at that drive, the LED side is easily driven from a 3.3V or 5V logic output through a series resistor. The 80V collector rating and 50mA output current give ample margin for 5V logic levels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP385BLL-TPRE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP385BLL-TPRE when reusing this data.
