Frequently Asked Questions
What is the maximum continuous collector current rating?
The DC Collector Current (I C) limit is -1.5 A, although a pulsed rating of -3 A is specified.
Does this transistor require special mounting conditions?
Yes; reliable power dissipation requires mounting the component on a 40 x 40 x 0.7[mm] ceramic substrate.
Is this part suitable for life-critical equipment or medical devices?
No, it is not designed for systems requiring an extremely high level of reliability where failure could pose a direct threat to human life.
How is the typical collector saturation voltage determined?
The datasheet shows that Vce(sat) is typically -0.4V when operated at I = -500mA and I = -25mA.
