Each channel consists of a GaAlAs infrared LED optically coupled to a silicon photo-detector, achieving 3750Vrms minimum isolation voltage. The device offers a wide current transfer ratio (CTR) range of 50% to 600% at IF=5mA, with 3 us typical propagation delay and 80V collector-emitter voltage rating. The compact MFSOP-16 package enables high-density isolation designs with a minimum creepage and clearance of 5.08mm. The device operates over a -55C to +125C temperature range and carries UL, cUL, and VDE safety approvals.","working_principle":"The TLP290-4 uses optical coupling to transmit electrical signals across an isolation barrier. (1) LED Transmitter: When forward current flows through the GaAlAs infrared LED (anode to cathode), it emits infrared light with intensity proportional to the forward current. (2) Optical Coupling: The emitted light crosses an optically transparent but electrically insulating dielectric barrier, providing galvanic isolation of 3750Vrms between input and output. (3) Photo-detector Receiver: The silicon photo-detector converts the received light back into electrical current. The ratio of output current to input LED current is the current transfer ratio (CTR), which ranges from 50% to 600% depending on operating conditions and device grade. (4) Signal Transmission: Digital signals are transmitted by switching the LED current on and off. The photo-detector output follows the LED input with a typical propagation delay of 3 us, suitable for signal rates up to approximately 100 kHz.","pin_description":"
