Frequently Asked Questions

What safety precautions should be taken when handling the BLF242?

The product contains beryllium oxide; handle the undamaged BeO disc carefully and dispose of it as special waste.

What is the maximum power dissipation for the BLF242 transistor?

The total power dissipation (P_tot) is up to 16 W at a mounting base temperature (T_mb) of 25°C.

What are the typical performance specs for CW class-B operation at 175 MHz?

At 175 MHz, with 28V drain-source voltage, it typically delivers 5W output power, >13dB gain, and >50% efficiency.

How is the BLF242 transistor packaged?

It comes in a 4-lead, SOT123 flange envelope with a ceramic cap, in an antistatic package.

What is the gate-source voltage limit for the BLF242?

The absolute maximum gate-source voltage is ±20 V.
