Photodiode Array Chips for SSR

Photodiode Array Chips for SSR


Photodiode Array Chips are designed to be used in solid state relays. SSR relays offer advantages compared to electromechanical arrays. The PDA chips we offer are high reliability, thermal conductivity and radiation immunity. SSR relay is a device that consists of PDA, an LED chip and a control IC chip.

A photodiode array is a type of semiconductor device that consists of multiple photodiodes arranged in a 2-dimensional array. Each photodiode in the array can detect light independently and generate a proportional electrical signal. Photodiode array chips can be used in Solid-State Relays (SSRs) as input devices to detect the presence or absence of an input signal.

In an SSR, the photodiode array chip can be used to isolate the control circuitry from the load circuitry. When a voltage is applied to the input terminals of the SSR, the photodiode array chip detects the input signal and generates a corresponding electrical signal. This electrical signal is then used to switch a transistor, which controls the load current.

Photodiode array chips for SSRs typically have a high sensitivity to light, fast response time, and low noise. They are commonly used in applications such as industrial control systems, motor control, and power switching.

It is important to note that photodiode array chips can have different configurations, such as linear arrays and 2D arrays, and can have different numbers of photodiodes depending on the specific application.
