The UK's ISOCOM Components 2004 Ltd. has launched two new generations of automotive-grade optocouplers, ISPQ9291X and ISPQ9185X, designed specifically for harsh automotive environments such as electric vehicle systems, highreliability industrial automation. With superior signal transmission and noise immunity, these devices provide more stable signal and power control solutions for a variety of fields.

ISPQ9291X: High-performance signal transmission device

ISPQ9291X is a high-performance single-channel optocoupler with a SSOP4 surface-mount package, featuring a core advantage of stable signal transmission and excellent anti-interference performance. Its high isolation grade of 3750Vrms effectively counters interference from complex electrical noise environments, ensuring robust operation of the equipment under harsh working conditions.

ISPQ9185X : High Adaptability Space Optimization Selection

ISPQ9185X is a high-performance single-channel optocoupler with SOP4 surface-mount packaging, which, in addition to reliable signal transmission and anti-interference performance, can also adapt to the layout of circuit boards with strict spatial requirements. With an isolation grade of 3750Vrms, it can still maintain excellent performance in high electrical noise scenarios.

Key features

• Compliance and certification, including industry standard certifications such as AECQ-102, UL1577, VDE DIN EN60747-5, etc., meeting automotive and industrial grade quality requirements, ensuring product compatibility and reliability.
• The working temperature range covers -55 ~ 125°C, easily coping with extreme high and low temperature working conditions, and is suitable for complex application environments such as automotive and industrial.
• Current Transfer Ratio (CTR) covering 50% ~ 600%, flexibly matching different scenarios' signal driving and transmission needs.
• Low working current, high isolation voltage > 3750Vrms, can effectively isolate electromagnetic interference between circuits, resist electrical noise
