Frequently Asked Questions

What is the maximum collector current (IC)?

The maximum continuous collector current (IC) rating listed in the datasheet is 30 mA.

Is this transistor sensitive to static electricity?

Yes, it is an ESD (Electrostatic discharge sensitive device), so observation of handling precautions is required.

What is the operating temperature range for this component?

The ambient temperature range (TA) is from -65 °C to +150 °C.

How do I measure the total power dissipation (Ptot)?

Ptot is measured on the collector lead at the soldering point on the PCB.
