Frequently Asked Questions
How can I easily set up an inverter circuit using this component?
The built-in bias resistors enable the configuration of an inverter circuit without needing to connect external input resistors.
What is the maximum allowable collector current (I(C)) for this device?
For the UMA9N, the absolute maximum rated collector current $I_{C(MAX)}$ is -100mA.
Can I use this component in life-critical systems like medical or aerospace machinery?
No. It should not be used for systems requiring an extremely high level of reliability (e.g., medical instruments), and you must consult a ROHM representative first.
What are the total power dissipation limits when using the FMA9A package?
The maximum permissible power dissipation ($P_D$) for the FMA9A model is 300mW.
