EL817C Optocoupler Phototransistor IC DIP-4
Rs. 3.80
Functionality: The EL817C is an optocoupler, also known as an opto-isolator. It typically consists of an infrared (IR) light-emitting diode (LED) on the input side and a phototransistor or photodarlington on the output side. The purpose is to transfer electrical signals between the input and output while maintaining electrical isolation.
DIP-4 Package: The "DIP-4" designation indicates that the IC is packaged in a Dual Inline Package with 4 pins.
Pin Configuration: The 4 pins of the EL817C are typically labeled as follows: Anode (A), Cathode (C), Collector (C), and Emitter (E).
Electrical Isolation: Optocouplers are used to isolate sensitive components or circuits from potentially noisy or high-voltage environments. The input signal (coming from the LED) does not directly electrically affect the output circuit (controlled by the phototransistor), providing a level of isolation.
Applications:
Common applications include signal isolation in power supplies, motor control circuits, microcontroller interfacing, and other scenarios where electrical isolation is necessary.Features
- Current transfer ratio (CTR: 50~600% at IF =5mA, VCE =5V)
- High isolation voltage between input and output (Viso=5000 V RMS)

- Operating temperature up to +110°C
Applications
- Programmable controllers
- System appliances, measuring instruments
- Telecommunication equipment
- Home appliances, such as fan heaters, etc.
- Signal transmission between circuits of different potentials and impedances
