Frequently Asked Questions
What is the primary benefit of using PUMD2 transistors?
They feature built-in bias resistors R1 and R2, which simplifies circuit design and reduces the required number of components and board space.
What are the ambient operating temperature limits?
The device can operate in an ambient temperature range from -65°C to +150°C.
Is specific mounting required for power calculations?
Yes, when determining total power dissipation (Ptotal), the note specifies that the device must be mounted on an FR4 printed-circuit board.
