Frequently Asked Questions

What is the functional composition of TLP124?

TLP124 is a photocoupler consisting of a photo-transistor optically coupled to a gallium arsenide infrared emitting diode.

How should TLP124 be wired based on its pin configuration?

The pins are configured as follows: Pin 1 = Anode, Pin 3 = Cathode, Pin 4 = Emitter, and Pin 6 = Collector.

What is the required precaution when handling the component?

Since Gallium arsenide (GaAs) is used, the dust and fumes are toxic. Do not break or cut the product, and follow appropriate waste disposal regulations.
