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.
WebThe Current Transfer Ratio (CTR) is an electrical parameter of an optocoupler. CTR, as a percen tage, is defined as the ratio ... Remarkably, Broadcom opto couplers project a lifetime perfor mance of just a 10% CTR drop fo r as long as millennium (few centuries). Figure 7 shows the centennial lifetime performance.
