Optoisolators, which consist of an LED Opto-coupler, are widely used in many applications to provide electrical isolation between circuits. The VO4158D-X007T optoisolator is a triac and SCR output optoisolator which provides fast switching speeds, long life, and excellent on-state voltage characteristics. It is ideal for commercial and automotive applications. This optoisolator has a wide range of applications such as: AC switching, motor speed control, power supply regulation, home appliances and many other consumer applications.

The VO4158D-X007T optoisolator is typically used in AC circuits and its working principle is based on the LED-phototriac structure. It consists of a gallium arsenide infrared LED which is optically coupled to the integrated triac and SCR switch. When the LED is activated, it emits an infrared light beam which is then detected by the phototriac, causing the triac and the SCR to switch on. The triac acts as a latching circuit, meaning it will remain on or off until the LED is deactivated. This ensures that the signal remains intact even in the event of a power failure.

The triac in the VO4158D-X007T optoisolator has a maximum blocking voltage of 600 Volts and a maximum holding current of 1.5 Amps. It also has a maximum switching frequency of 400 kHz and an on-state voltage drop of 1.4V. It also has a maximum AC power dissipation of 10 Watts and a minimum collector-emitter saturation voltage of 2V. Additionally, the optoisolator also features a peak operating temperature of 125°C and a storage temperature of -40°C to +125°C. All these features make the optoisolator ideal for many commercial and automotive applications.The VO4158D-X007T optoisolator features a high isolation rating of 3.75kV rms, making it suitable for data and signal transmission applications. It also has low propagation delay and delay skew, which makes it ideal for Ethernet, USB and other high-speed communication systems. Additionally, the optoisolator has an open collector output design, which allows it to be used in both logic-level and non-logic level circuits. Its tight hold-on characteristics enable it to latch on signal with as little as 10ns of input rise/fall time.

The VO4158D-X007T optoisolator is an ideal choice for applications where high performance is required. Its features make it an ideal solution for applications such as AC switching, motor speed control and power supply regulation. It is also suitable for use in home appliances and other consumer applications. It is RoHS compliant and available in an 8-pin DIP and an 8-pin SOIC package.
