What is the ACPL-K49T-060E?
It is a high-isolation optocoupler with a phototransistor output, designed to provide safe electrical isolation and signal transfer in high-voltage environments.
What are its key features?
Key features include a 5000 Vrms isolation rating, high common-mode rejection (30 kV/μs), low LED drive current (4 mA typical), compact SO8 package, wide operating temperature range (–40°C to +125°C), low propagation delay (20 μs max), and compliance with automotive-grade AEC Q100 standards.
What applications is it used for?
This optocoupler is commonly used in automotive digital interfaces, power supplies, battery management systems, and industrial equipment where reliable isolation and noise immunity are critical.
Why is electrical isolation important?
Isolation protects low-voltage control circuits from high-voltage power sections, preventing damage and improving safety in sensitive electronic systems.
Are there alternative parts available?
Yes. Similar optocouplers from Broadcom’s ACPL series or other manufacturers like Vishay and Texas Instruments can be considered, depending on isolation voltage, speed, and package requirements. Always check for pin compatibility and performance before selecting alternatives.
Where can I buy the ACPL-K49T-060E?
