WebJul 13, 2024 · The 4N35 is an optocoupler for general applications. It contains a light-emitting diode that is optically coupled to a phototransistor. It uses a 6-pin DIP package and provides wide lead spacing options and lead bending SMD options. The response time is usually 3 µs, and the minimum CTR at an input current of 10 mA is 100%. Web(1)CTR degradation Light output of the LED in the photocoupler decreases gradually over time, contributing to CTR degradation. It is, therefore, advisable to provide a design margin to offset this anticipated CTR degradation. (2)CTR - IF dependency When a transistor coupler is used with low input current, its CTR drops as shown in Figure 1.3.
WebCTR is 50% at input current of 5 mA. Schematic Functional Diagram Features Current transfer ratio (CTR: minimum 50% at IF = 5 mA, VCE = 5V) High input-output isolation voltage (Viso = 3750 Vrms) High collector-emitter voltage (VCEO = 80V) Response time (tr: typical, 4 μs at VCE = 2V, IC = 2 mA, RL = 100Ω) WebDec 10, 2024 · Of the 3 cases who needed CTR during surgery, one case had severe phacodonesis, and 2 cases had mature cataracts in the preoperative slit-lamp examination. One of the safe techniques which is commonly used for patients with zonular instability is vertical chopping, particularly when working within the confines of a small pupil.
