The LCR-1506 optical coupler from SENBA is a high-reliability isolation component designed for efficient signal transfer between electrically isolated circuits. Utilizing advanced optoelectronic coupling technology, it ensures safe and noise-immune communication in industrial, power, and embedded applications.
This optocoupler features a dual in-line 4-pin (DIP-4) package, supporting an input current range of 0–20mA with a maximum of 40mA, and an input voltage of 1.3–2.5VDC. Its high insulation voltage rating of over 2500VRMS provides strong electrical isolation, protecting sensitive components from high-voltage transients and noise interference. With a working frequency of up to 300kHz, the LCR-1506 enables fast signal switching, making it suitable for high-speed control and communication systems.
Designed for stable operation, it performs reliably across a temperature range of -30°C to +70°C and supports storage conditions from -40°C to +80°C. Compared to lower series optocouplers, the LCR-1506 offers enhanced current handling, improved switching performance, and superior long-term reliability.
The compact DIP-4 package ensures easy PCB integration, making it ideal for both prototyping and production applications.
