Frequently Asked Questions
What application makes these transistors ideal?
Their low saturation voltage and ability to handle high current make them perfect for muting circuits.
What are the absolute maximum operating limits of this transistor?
The collector current (IC) must not exceed 600 mA, and the junction temperature (Tj) limit is 150°C.
Can these transistors be used in critical life-safety equipment like medical devices?
No; for applications needing extremely high reliability (e.g., aerospace or medical instruments), you must consult a sales representative first.
