Optoisolators provide electrical insulation between the transmitter and receiver, effectively blocking high voltages and other hazardous signals. The PS9687L2-E3-A is a type of optoisolator which falls into the Logic Output category because it’s designed to provide a logic output signal. This optoisolator consists of a phototransistor that is optically coupled to an infrared LED, which means it is able to convert optical signals to electrical signals.

The PS9687L2-E3-A optoisolator is especially useful when it comes to protecting sensitive equipment from overvoltage damage. It can tolerate surge currents up to 8.3A and withstand surges up to 50V. A common application field for this optoisolator operates on PCBs in automotive or industrial applications where it is used to isolate LVDS (low voltage differential signal) level signals.

The working principle of this optoisolator is relatively simple. It consists of two parts, a receiver part and a transmitter part. The transmitter part includes the LED (which creates the optical signal) and the receiver part includes the phototransistor, which converts the optical signal into an electrical signal. The LED transmits an infrared light signal which triggers the phototransistor to turn on and off depending on the level of the signal.

When the infrared light is received by the phototransistor, it will react to create an electrical output signal that is logic level. This logic level output signal means that digital logic circuits will be able to read and interpret the signal easily. This optoisolator is also equipped with a wide operating temperature range (–40°C to 105°C) and long lifetime so it is ideal for dynamic applications that require long-term performance.

The PS9687L2-E3-A is an ideal choice when it comes to logic output optoisolators. Its robust design makes it suitable for use in a variety of industrial and automotive applications. It is able to provide efficient and effective optical signal to electrical signal conversion while protecting against overvoltage damage. It is a cost-effective choice that offers robust performance in tough conditions.
