Optoisolators are semiconductor devices specifically designed to provide electrical isolation between an input and an output. They achieve this by using an optical link between the two sections. This isolates the input from the output electrically; any voltages, currents, or noise present at the input do not affect the output. The EL3023S(TB)-V optically coupled triac or SCR output module, is one such optoisolator.

The EL3023S(TB)-V is available in either a surface mount or through-hole package and has dual 25A outputs. It provides outstanding performance with a maximum disconnection time of 250ns minimum, a delay time of 300ns maximum, a common mode transient immunity of 15kV/µs minimum and a surge reverse voltage rating of 1,500V minimum. It has an operating temperature range of -40°C to 85°C.

The EL3023S(TB)-V utilizes an infrared LED coupled to a Bidirectional Triac or SCR output. This type of optoisolator is most frequently used to provide electrical noise isolation. It can also be used to provide control of AC line powered loads from an isolated control circuit. The LED within the optoisolator component is driven by a DC current which causes it to emit a light signal. This signal is then received by the bidirectional Triac or SCR output and, similarly to a transistor, is activated by current from the LED emitter.

The optoisolator is suitable in applications for home appliances, office equipment, personal computers, peripherals, household appliances, AV equipment, and other areas where low input control is necessary. In addition, they can be used for single-phase motor control, relay control, light dimming, temperature control, and DC AC switching.

The EL3023S(TB)-V has several important characteristics which make it very useful. Firstly, it provides an extremely low forward voltage drop, allowing for higher power output. Secondly, it possesses a higher current carrying capacity (25 Amps max) than some other opto-couplers, making it more desirable in applications where high current is necessary. Thirdly, its bidirectional Triac or SCR output allows it to be used in applications in both AC and DC circuits, bringing more versatility and applications to this optoisolator.

Finally, this optoisolator contains a unique OneMotion™ feature. This feature helps to reduce the voltage drop and prevents the loss of power by self-triggering the Triac or SCR when the LED current is too low. This makes the EL3023S(TB)-V a good choice for applications with low LED current.

In summary, the EL3023S(TB)-V optoisolator has been designed to provide electrical noise isolation, control of AC line powered loads, high power output, high current carrying capacity, and a OneMotion™ feature for low LED current applications. This optoisolator has been widely used in home appliances, office equipment, personal computers, peripherals, and other areas for its versatile characteristics.
