Optoisolators - Transistor, Photovoltaic Output

An optoisolator, also known as an optoelectronic isolator, is a specific type of electrical isolators that uses a light-emitting diode (LED) to provide electrical insulation between two circuits. This type of device can be used to prevent electrical overvoltage or high-current paths from the one circuit to another. Optoisolators can be used to provide electrical isolation of AC or DC signals, power supplies, and logic signals.

The H11A1FR2VM is a one-channel, transistor-output optoisolator that features a 750Vrms isolation rating. It is designed to couple high-frequency or high-speed digital signals with optical isolation protection in various control and interface applications. The device can also be used to provide physical insulation of voltage levels between two circuits. The H11A1FR2VM consists of a 435nm LED housed in an epoxy-molded package, and a MOSFET transistor in a surfacemounted controller. The LED provides light energy to the MOSFET transistor, which detects changes in the LED’s light intensity. When the LED is activated, the bipolar transistor is turned ON or OFF, based on the detected light level.

The H11A1FR2VM is designed for use with +3.3V to +5V DC supply voltage, and it has a maximum current capacity of 5mA. The device provides high-speed optical isolation of up to 20Mbps and a wide commonmode transient immunity range of 5kV/µs. The optocoupler also has a low average forward voltage of 1.3V and a high on-state current gain of 250%. The low footprint of the package allows it to be used in space-constrained designs, such as home appliances and consumer electronics.

The H11A1FR2VM can be used in a wide variety of applications, such as microcontroller and logic control, telecommunications, industrial control, medical equipment, and automotive control systems. The optoisolator can also be used in switch debouncing and sensing applications, motor control, power supply protection, and signal buffer isolation.

The H11A1FR2VM optoisolator is an essential component in many applications, providing safety and reliability. By keeping high-voltage or high-current paths from one system to another, the optoisolator ensures that both circuits remain electrically and physically isolated. It provides accurate data and control signals in a wide variety of applications, making it an ideal choice for both commercial and industrial applications.
