MCT2E Description

Short technical summary and product information.

The MCT2E is a phototransistor optocoupler manufactured by QTC, designed to provide high-voltage electrical isolation between two circuits. It consists of an infrared-emitting diode optically coupled to a silicon npn phototransistor.

 

Key electrical specifications include a typical input diode forward voltage of 1.25V and a maximum collector-emitter voltage of 30V. The device offers a typical on-state collector current of 5mA and features typical rise and fall times of 5µs, indicating good switching speed.

 

This optocoupler is housed in a plastic dual-in-line package (PDIP). It operates within a temperature range of -55°C to 100°C. The MCT2E is suitable for applications requiring isolation from noisy digital electronics or for interfacing circuits with different voltage levels.

 

It is designed to be compatible with standard TTL integrated circuits and offers a high direct-current transfer ratio. The base lead is provided for conventional transistor biasing, although it is often unused in standard phototransistor mode.
