It provides 5000Vrms of galvanic isolation between a DC input LED and a phototransistor output, with a current transfer ratio (CTR) ranging from 50% to 600% at a forward current of 5mA. This part is suited for industrial control interfaces, PLC I/O modules, motor drive feedback, and any application requiring reinforced isolation between logic-level signals and higher-voltage circuits. The -55°C to 110°C operating temperature range covers most industrial and some automotive environments without derating. The 5000Vrms isolation rating is the headline safety spec. It qualifies this optocoupler for reinforced insulation in mains-connected equipment — think AC motor drives, switched-mode power supply feedback, and industrial sensors that must survive transient overvoltages without bridging the safety barrier. For a procurement decision, this rating is non-negotiable: if your design requires 5000Vrms, the TLP385(D4GL-TL,E fits without margin questions. If your application only needs basic isolation at 2500Vrms, you could step to a lower-rated part and save board area, but the 6-SOIC-4 footprint here is already compact. ## CTR range — matching the LED drive to the load The CTR window of 50% to 600% at 5mA forward current is wide. That means the same part can work with a low-drive microcontroller pin (CTR on the high side) or a high-drive logic output (CTR on the low side), as long as the load-side collector current requirement falls within the product of CTR and forward current. For a typical 5mA input, the output can sink between 2.5mA and 30mA — enough to drive a logic gate input, a relay coil via a transistor, or an LED indicator. The wide spread also means you should design for the minimum CTR to guarantee operation across temperature and LED aging; the 50% floor at 5mA gives a 2.5mA guaranteed output. ## Lifecycle and supply posture No last-time-buy or end-of-life notification is on file.
