TLP127 Darlington Output Optocoupler IC – SMD SOP-4

Description

The TLP127 is a high-gain, small-outline optocoupler IC designed for space-constrained surface-mount applications. It features a gallium arsenide (GaAs) infrared-emitting diode optically coupled to a high-gain Darlington phototransistor. To ensure stable operation and improved noise immunity, the phototransistor includes an integrated base-emitter resistor.

With a high collector-emitter voltage rating of 300V and a massive Current Transfer Ratio (CTR) of 1000% minimum, this device is exceptionally efficient at switching high-voltage loads using low-current control signals. Its compact SOP-4 package is perfect for modern, high-density PCB designs where reliable galvanic isolation is required.
