In modern electronic systems, signal isolation and transmission between circuits are crucial. To ensure the safety and reliability of the system, Optocouplers are widely used as a common isolation device. The SL-1009 optocoupler is a high-performance optocoupler that is widely utilized for isolation and transmission in electronic systems.

SLKOR optocoupler SL-1009

Firstly, the opto-transistor detector in SL-1009 does not contain halogens and Sb2O3, which is environmentally friendly and safer. In modern electronic devices, the demand for environmentally friendly and non-toxic materials is increasing. In this regard, SL-1009 meets these requirements very well. Secondly, this component adopts a 4-pin SOP package, which is small, compact, and easy to install and layout. It is suitable for various circuit board designs and can perform well in limited space.

The main features of SL-1009 include a high current transfer ratio (CTR) of up to 50% (when IF = 5mA, VCE = 5V, Ta-25℃), which means that it can provide higher photoelectric conversion efficiency; a high insulation voltage of up to 5000Vrms, which can effectively isolate input and output signals and ensure system safety; a high collector-emitter voltage (VCEO) of 70V, which enables SL-1009 to withstand higher power and voltage; a wide temperature range, which can operate normally in environments from -55℃ to 110℃; a long creepage distance greater than 8mm, which provides better insulation performance. In addition, this component is also a lead-free product, compliant with RoHS standards, and meets environmental requirements.
