Frequently Asked Questions
What is the required collector-base voltage (V_CBO) rating?
The absolute maximum rated limit for V_CBO is -50 V.
How easily can I incorporate this device into a design?
It is designed to be easy, requiring only setting the 'on' / 'off' condition (GND and IN).
What environmental conditions should I consider when designing circuits?
For mass production, peripheral conditions must be taken into account when designing circuits.
