Frequently Asked Questions

What types of circuits can this transistor power?

It is suited for medium power peripheral drivers (e.g., fans/motors), strobe flash units, and battery chargers.

What is the maximum DC collector current I can handle?

The continuous collector current (IC) is rated at 5A. However, peak current (ICm) can reach 10A for pulses t ≤ 1ms.

How does the mounting board affect heat dissipation?

Thermal resistance varies significantly; a 7 cm ceramic PCB provides Rth(j-a) of 80 K/W, while standard footprints are higher (c. 10 K/W).
