MMBT4124

NPN General Purpose Amplifier

This device is designed as a general purpose amplifier and switch.

The useful dynamic range extends to 100 mA as a switch and to

100 MHz as an amplifier.

Absolute Maximum Ratings*

TA = 25°C unless otherwise noted

NOTES:

1) These ratings are based on a maximum junction temperature of 150 degrees C.

2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
