WebThe current transfer ratio (CTR) is also a function of temperature. For example, the current transfer ratio (CTR) can vary or change as the temperature (e.g., the operating temperature of the optocoupler system 100) changes. This variation in CTR due to temperature variations is referred to as a temperature coefficient or “tempco” of the CTR.

WebMar 21, 2015 · There are numerous acceptable devices –see matrix. All these devices are current with DigiKey and most cost less than $1. Also, all are in the DIP-8 package so they may be easily plugged into a protoboard. All have CTR (current transfer ratio) ranging from 50% to about 500% –quite sloppy. Web• Operating ambient temperature: 110°C • High Isolation voltage (BV = 5 000 Vr.m.s.) • High collector to emitter voltage (VCEO= 80 V) • High current transfer ratio (CTR = 450% TYP.) • High-speed switching (tr= 5 μs TYP., tf= 7 μs TYP.) can sudden stress amplify an infection
