Optoisolators - Transistor, Photovoltaic Output

The OPIA414BTRA photovoltaic output transistor optoisolator is an integrated circuit consisting of a low current phototransistor optically coupled to an integrated circuit driver. This series of optoisolator incorporates a GaAlAs LED (light emitting diode) and a high gain NPN phototransistor on a single monolithic chip in an 8-pin dual-in-line package. The photo current can be adjusted by changing the LED forward current to optimize the optoisolator performance for various input and output requirements. This optoisolator offers significant advantages over conventional electrical isolators such as galvanic isolation and the ability to transmit signals from low voltage circuits to high voltage circuits.

Application Field

The OPIA414BTRA photovoltaic output transistor optoisolator is suitable for a variety of applications such as buffering, level shifting, signal isolation, noise immunity, galvanic isolation, etc. It can be used for AC or DC current signal transmission across a large common mode voltage range, and for handling small DC current signals as well. This optoisolator is especially suitable for digital data signal transmission across low and high voltage, as well as for power line isolating applications.

Working Principle

The working principle of the OPIA414BTRA photovoltaic output transistor optoisolator is based on the principle of optical isolation. When an electrical signal is applied to the LED of the optoisolator, the light emitted by the LED is directed onto the phototransistor, causing a current to flow in the phototransistor. This current is then amplified by the integrated circuit driver and can be used for transmission of data or control signals. At the same time, the optoisolator provides galvanic isolation, meaning that the input and output circuits of the device are electrically isolated. This makes it suitable for use in applications where the input and output must be isolated for safety and reliability.

The OPIA414BTRA photovoltaic output transistor optoisolator offers high linearity over the full range of input and output levels, and ensures low power consumption and high speed operation. It is suitable for operation in temperatures between -40°C and +85°C, and has a very low propagation delay. In addition, its long life and fast switching speed makes it a suitable choice for many applications.

In summary, the OPIA414BTRA photovoltaic output transistor optoisolator is an efficient, reliable and cost-effective solution for electrical isolation, signal transmission and level shifting applications. It is suitable for a variety of applications and provides high linearity, low power consumption and high speed operation.
