Frequently Asked Questions
How do built-in resistors simplify circuit design?
They enable circuits, like inverters, without requiring external input or biasing resistors.
Can these transistors be used for life support or safety critical systems?
No. They are not designed for equipment where failure could threaten human life, such as medical instruments or aerospace machinery.
What is the typical collector-emitter saturation voltage (V_CE(sat))?
The CE(sat) voltage specified in the characteristic diagram is typically -0.3V.
Is this component suitable for modern environmental standards?
Yes, the DTA114T series products are Lead Free and comply with RoHS directives.
