Additional Details

The TLP104(TPL.E typically features an isolation voltage of several kilovolts, ensuring robust protection. The current transfer ratio (CTR) ranges depending on the specific grade but provides efficient signal coupling. The input forward voltage is around 1.2V, and the collector-emitter voltage rating is specific to the device specifications. It is available in a small outline package (SOP), which is suitable for surface mount assembly. The operating temperature range is usually from -55°C to +100°C. It is widely used in applications where galvanic isolation is crucial for safety and performance.
