PS8352AL2

The PS8352AL2 is a high-performance optocoupler manufactured by Renesas Electronics Corporation, designed for reliable signal isolation in demanding industrial and automotive applications. It features a gallium arsenide infrared LED as the input side, which provides stable light emission over time and across temperature variations, ensuring consistent operation under harsh environmental conditions. On the output side, the device incorporates a photo-transistor detector that delivers fast response times and low propagation delay—typically less than 10 µs—making it suitable for high-speed digital communication interfaces. The component offers a high isolation voltage of up to 5000 Vrms, meeting stringent safety standards such as UL 1577 and IEC 60747-17, which is critical for protecting sensitive circuits from high-voltage transients or ground potential differences. The PS8352AL2 is housed in a compact 6-pin DIP package, offering ease of integration into printed circuit boards while maintaining mechanical robustness. Its wide operating temperature range—from -55°C to +125°C—enables use in extreme environments, including automotive engine control units, power supplies, and industrial automation systems. Additionally, the device exhibits excellent common-mode transient immunity (CMTI), typically exceeding 25 kV/µs, which enhances noise resilience in electrically noisy environments. This optocoupler supports a continuous current transfer ratio (CTR) of 50% to 600%, allowing flexibility in design while maintaining signal integrity across varying load conditions. The internal structure ensures minimal crosstalk between input and output, improving overall system reliability. Furthermore, the PS8352AL2 is lead-free and RoHS-compliant, aligning with modern environmental regulations and sustainable manufacturing practices. It is commonly employed in isolated gate drivers for power MOSFETs and IGBTs, medical equipment, PLCs (Programmable Logic Controllers), and data acquisition systems where electrical isolation prevents ground loops and safeguards both human operators and electronic components. Its combination of speed, reliability, and compliance makes it an ideal choice for engineers seeking robust isolation solutions in high-reliability applications.
