Opto coupler A1458 is a type of optoelectronic device that uses light to transfer electrical signals between two isolated circuits. It consists of an infrared LED and a phototransistor packaged in a single housing. The LED emits light when a voltage is applied to its input, and the phototransistor detects the light and generates a corresponding output voltage. The opto coupler A1458 can be used for various applications, such as signal isolation, switching, logic interfacing, and noise suppression.
It has a high isolation voltage of 3750 Vrms, which means it can withstand high voltage differences between the input and output circuits without breaking down.
It has a fast switching speed of 1 Îs, which means it can transfer signals quickly and accurately.
It has a low input current of 1.6 mA, which means it consumes less power and generates less heat.
It has a wide operating temperature range of -55ÂC to +100ÂC, which means it can function reliably in various environments.
It has a standard SO-8 surface mount package, which means it can be easily soldered onto printed circuit boards.
How to Use Opto Coupler A1458
To use opto coupler A1458, you need to connect its input pins (1 and 2) to the source circuit, and its output pins (5 and 6) to the destination circuit. You also need to connect its common pins (3 and 4) to the ground of the source circuit, and its common pins (7 and 8) to the ground of the destination circuit. The input pins can accept a voltage range of 1.5 V to 20 V, and the output pins can provide a voltage range of 4.5 V to 20 V. The input current should not exceed 50 mA, and the output current should not exceed 25 mA.
Example Circuit Using Opto Coupler A1458
Here is an example circuit that uses opto coupler A1458 to isolate a microcontroller from a relay. The microcontroller sends a logic signal (0 or 1) to the input of the opto coupler, which then turns on or off the LED inside. The phototransistor inside the opto coupler detects the LED status and switches on or off the relay accordingly. The relay can control a high-voltage load, such as a lamp or a motor. The opto coupler prevents any electrical interference or damage from the load circuit to the microcontroller circuit.
