TLP281(GB-TP,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP281(GB-TP,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an aluminum gallium arsenide infrared emitting diode with a phototransistor, housed in a compact SOP-4 surface-mount package. The device provides electrical isolation between input and output circuits, featuring a minimum collector-emitter voltage of 80V and a minimum isolation voltage of 2500 Vrms. The current transfer ratio (CTR) for the GB rank ranges from 100% to 600%, measured at a forward current of 5mA and collector-emitter voltage of 5V. Typical switching times include a rise time of 2μs and a fall time of 3μs. The component operates within a temperature range of -55°C to 100°C and complies with UL 1577 and BSI safety standards.
