CTW4503 Datasheet | CT Micro

Features Description - High speed 1MBit/s - High isolation voltage between input and output (Viso=5000 Vrms ) - Guaranteed CTR performance from 0°C to 70°C - Operating temperature range -55°C to 100°C - MSL class 1 - Regulatory Approvals - UL - UL1577 (E364000) - VDE - EN60747-5-5(VDE0884-5) - CQC - GB4943.1, GB8898(19001231774) - IEC62368 (FI/41119) The CTW135, CTW136, CTW4502, and CTW4503 devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor. The device is packaged in an 8-pin wide body DIP and also available in surface mount option. Applications - Line receivers - Telemunication equipment - High speed logic ground isolation - Feedback loop in switch-mode power supplies - Home appliances Package Outline Schematic Note: Different bending options available.
