The input is a DC-driven IR LED with a typical forward voltage of 1.25V; the output is a phototransistor rated for 80V collector-emitter and 50mA continuous current. ## CTR window: 100% to 200% at 5mA The current transfer ratio is specified as a minimum of 100% and a maximum of 200%, both measured at 5mA forward current. That 2:1 spread is tighter than many general-purpose optocouplers, which means less variation in the collector current from unit to unit. For a digital input where you are sinking a logic gate, the 100% floor guarantees at least 5mA on the output side at 5mA input — enough to drive a standard CMOS or TTL load without extra gain stages. The 200% ceiling prevents the output from saturating too hard, keeping turn-off time predictable. ## Switching speed: 2µs rise, 3µs fall Rise and fall times are 2µs and 3µs typical, with turn-on and turn-off both at 3µs. ## Temperature range and environment Operating temperature range is -55°C to 110°C.","metaTitle":"TLP385(GRL,E Toshiba Optocoupler, 5000Vrms, 100-200% CTR","metaDescription":"Toshiba TLP385(GRL,E single-channel transistor optocoupler, 5000Vrms isolation, 100-200% CTR at 5mA, 80V output, -55 to 110°C.

The difference is the CTR bin: TLP385(GRH,E has a higher CTR range (200% to 400%) versus the 100% to 200% of the GRL variant. Choose GRH when you need more output-side current gain at the same input drive; stick with GRL for a tighter gain window that limits saturation depth."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/toshiba/TLP385GRLE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/toshiba/TLP385GRLE when reusing this data.
