Frequently Asked Questions

Q: What is the complementary NPN transistor to pair with 2SA952?
A: The 2N4401 or BC547 can be used as complementary NPN transistors for balanced push-pull output stages and differential amplifier circuits.

Q: Can the 2SA952 be driven directly from 5V logic?
A: Yes, the 2SA952 works well with 5V and 3.3V logic signals. Ensure proper base current limiting (typically 10–100 µA) via a resistor to avoid saturation or damage.
