STMicroelectronics USB6B1 - USB Port Transient Suppressors
The USB6B1 from STMicroelectronics is a dedicated device designed to protect sensitive equipment connected to a USB (Universal Serial Bus) port. This monolithic application-specific transient suppressor integrates a series of diodes that effectively clamp transient overvoltages to a safe level, ensuring the protection of the USB transceivers in any electronic equipment.
Key Features
- Stand-off voltage: 6 V
- Peak pulse current: 5 A (8/20 µs)
- Low clamping factor
- Fast response time
- Very small PCB area occupation
- ECOPACK®2 compliant component for sustainable environmental requirements
The USB6B1 is specifically designed to protect the data lines and power lines in USB interfaces from electrostatic discharges (ESD), electrical fast transients (EFT), and other harmful transient voltage events. Its low clamping voltage ensures that any transient overvoltage is quickly clamped to a safe level, preventing damage to the protected device.
Applications
The USB6B1 is suitable for a wide range of applications where USB ports require protection from voltage transients. These include:
- Desktop and laptop computers
- Consumer electronics such as TVs, set-top boxes, and gaming consoles
- USB hubs, docks, and chargers
- Communication systems
- Portable devices
With its compact SO-8 package, the USB6B1 occupies minimal space on the PCB and can be easily implemented in space-constrained designs. It is also compliant with the ECOPACK®2 standard, which ensures that the device meets the latest environmental regulations free from hazardous substances.
Overall, the STMicroelectronics USB6B1 is an essential component for any design that requires robust protection for USB ports. It offers a reliable and cost-effective solution to safeguard your electronic devices from the potential damages caused by transient voltage events.
