Frequently Asked Questions
What is the collector power dissipation rating?
The total collector power dissipation ($P_C$) for both devices is 300 mW.
Are bias resistors built into this device?
Yes, it includes built-in bias resistors with values R1: 2.2kΩ and R2: 47kΩ to simplify circuit design.
Can the RN4605 be used in mission-critical systems?
No; it is not warranted for use in equipment requiring extraordinarily high reliability, such as medical or airplane instruments (Unintended Usage).
What is the maximum junction temperature?
The maximum junction temperature ($T_j$) rating is 150 °C.
