Optoisolators – Transistor, Photovoltaic Output – are widely used in electronic circuits to provide isolation between two circuits, typically, between a high voltage circuit (often an AC main) and a lower voltage circuit (often a low voltage controller). The PS8502L3-E3-AX is an example of such a device, specifically, a photovoltaic output transistor optoisolator.

An optoisolator is a device that consists of two parts, an LED (Light Emitting Diode) and a photosensitive receiver. The LED produces light of a specific wavelength when it is forward biased, and the receiver will convert that light into a voltage suitable for use in the lower voltage circuit. A photovoltaic output optoisolator works in a similar manner, but the output is a current rather than a voltage. The PS8502L3-E3-AX, in particular, is designed to provide a 2.5mA output current when exposed to an illumination level of 40mW/cm2.

The PS8502L3-E3-AX is an ideal choice for applications that require a very stable electrical isolation barrier. The device features a wide range of operating temperature (-40°C to 100°C) and a low minimum forward voltage drop of 1.2V. Additionally, the device’s high voltage blocking capability of 300VAC/DC makes it suitable for use in a wide variety of circuits.

The PS8502L3-E3-AX optoisolator is typically used to provide a signal coupling between circuits that operate on different power sources and levels. As an example, it is often used to bridge the gap between a high voltage AC circuit and a low voltage DC control circuit. In this application, the optoisolator allows the control circuit to detect the high voltage AC signal without the possibility of electrical shock to the user. The output of the optoisolator is then used to trigger a relay or other device in the control circuit.

The PS8502L3-E3-AX optoisolator is also well-suited for applications that require a low-power, isolated signal source, or a current output. For example, the device can be used to activate a transistor switch, allowing the external circuit to be turned on or off without a direct connection between the two. Additionally, the device’s optically isolated output means that it can be used in applications that require a high degree of noise immunity, such as automotive circuits, or even in hazardous locations where the possibility of an electrical shock must be eliminated.

Overall, the PS8502L3-E3-AX optoisolator is a highly reliable device for providing electrical isolation while still allowing a low-power control signal to be passed between circuits. Its low forward voltage drop, wide operating temperature range, and high voltage blocking capabilities make it an ideal device for a wide variety of applications, both in industrial and consumer electronics. With its simple design and ability to pass control signals in an electrically isolated manner, the PS8502L3-E3-AX is a versatile and reliable optoisolator.
