Frequently Asked Questions
How can I configure an inverter circuit using this series?
The built-in processors enable the configuration of an inverter circuit without requiring external input resistors.
What are the absolute maximum voltage limits for the supply and input?
The absolute maximum rating specifies a supply voltage of 50V CC, with allowable input voltages ranging from -5 to +30V.
Is this transistor suitable for safety-critical or medical equipment?
No. It should not be used in devices where failure could result in a direct threat to human life or injury.
Do I need to add external resistors for circuit biasing?
No, the built-in bias resistors allow the configuration of the circuit while eliminating the need for connecting external input resistors.
