Description
This NPN transistor has been designed for applications requiring high
voltage blocking. The SOT23F package is pin compatible with the
industry standard SOT23 foot print but offers lower profile and higher
dissipation for applications where power density is of utmost
importance.
Features
• High voltage
• Low saturation voltage
• Low profile small outline package
Applications
• Modems
• Telecoms line switching
