The MOCD213M is an optoisolator that utilizes a photovoltaic output and a transistor to offer isolation and galvanic protection for sensitive electronic circuits. It is an ideal choice for industrial, consumer and medical applications. It has a wide array of applications in isolation, interface and safety protocols.  

The MOCD213M optoisolator consists of an infrared emitting diode and an NPN silicon photo-transistor. The emitting diode is driven by an external current to provide an isolated voltage output. The driving current must be maintained within specific range in order to have a stable function of the device. The  photo-transistor is used to sense the emitted infrared radiation and thus produces an output voltage, usually in the order of a few volts.

The output produced by the device is used for controlling other circuits, as it offers micro-electrical isolation from the driving circuit. Isolation is important as it prevents high voltage signal or current from controlling sensitive circuits. It also helps to protect against voltage spikes and other high frequency noise which could damage the other connected circuit.

The working principle of MOCD213M optoisolator is to convert input current into an output voltage across the connected circuit. This is done by optically coupling the emitting diode and the photo-transistor together, thus having a very low leakage current between the two.  This output voltage is then further used as the gate voltage for controlling another electronic circuit. The output current of the circuit is then directly proportional to the external input current supplied to the device.

The MOCD213M optoisolator is typically used in applications such as circuit protection, EMI/RFI interruption, gate drive protection and signal transmission. It can also be used for industrial automation, motor control, automotive electronics and avionics applications. It is also suitable for consumer and medical applications, where voltage isolation is of prime importance.

Since the MOCD213M optoisolator provides electrical and optical isolation, it is able to reduce the risk of electrical failures and damage to the connected circuits by protecting against external voltage spikes. This device ensures a stable output voltage and current level even when the input voltage is unstable. Moreover, it is also easy to install and requires minimal maintenance.

The MOCD213M optoisolator is available in different package forms such as DIP, SMT, and through-hole. It has a wide operating temperature range and offers high reliability with a long operational life. Packed with great features, this MOCD213M optoisolator is an ideal solution for providing electrical isolation to sensitive electronics.
