Optoisolators, also known as optical couplers, are essential components in many electronic systems,used for electrical isolation and signal conversion between different levels of circuits. The 5962-8876801YA is one such optoisolator, specifically a logic output module.

Introduction

The 5962-8876801YA optoisolator is designed to provide electrical isolation between circuits that use different levels of logic. This optoisolator uses a physical barrier between the input and output circuits, blocking the exchange of electric signals between them. Instead, the optoisolator uses an optical link to send signals from one circuit to the other. This allows electric signals to be transmitted securely, while providing a reliable level of isolation and preventing the potential for ground loop problems.

Application Fields

The 5962-8876801YA optoisolator integrates a Gallium Arsenide Infrared Emitting Diode (IRED) with a silicon NPN phototransistor. It is designed to work in applications using TTL logic, such as industrial equipment control and process control. The logic input levels of the module are compatible with most logic circuits, including TTL, CMOS, and negative logic.

The 5962-8876801YA optoisolator is also used in switching power supplies, medical electronics, automotive electronics, instrumentation, as well as a variety of consumer electronics, such as computers, tablets and cell phones.

Working Principle

The 5962-8876801YA optoisolator works by using a Gallium Arsenide (GaAs) infrared emitting diode (IRED) and a silicon NPN phototransistor. When a TTL input signal is applied to the optoisolator, the IRED emits an infrared light. This light is received by the photosensitive base of the transistor and changes its current gain, causing a change in the output voltage according to the input signal.

The 5962-8876801YA optoisolator has an internal voltage regulator which stabilizes the voltage and keeps the transistor in an off-state until a TTL input signal of sufficient magnitude is applied. Additionally, the optoisolator is designed to be reverse polarity protected, meaning that it will not be damaged if connected to a power source of higher voltage than expected.

Features

The 5962-8876801YA optoisolator offers a strong electrical isolation (up to 5000VRMS for 1 minute), as well as a wide input voltage range (4V- 15V). It also features high speed switching of up to 5MHZ and a maximum output current up to 20mA. Additionally, the optoisolator is very compact in size, which makes it an ideal solution for applications with limited space.

Moreover, the 5962-8876801YA optoisolator has been designed to withstand relatively high temperatures (up to 125°C). Its robustness makes it suitable for use in harsh environments. The optoisolator is also designed to be RoHS compliant and is UL-recognized for safety.

Conclusion

The 5962-8876801YA optoisolator is a versatile and robust component designed for use in industrial, automotive, instrumentation and consumer applications. The optoisolator provides a strong level of electrical isolation, while also offering a wide input voltage range, high speed switching and a maximum output current of up to 20mA. Moreover, it is UL-recognized for safety and RoHS compliant.
