BC846A / BC846B / BC847A / BC847B / BC847C

NPN General Purpose Amplifier

This device is designed for low noise, high gain, general purpose
amplifier applications at collector currents from 1.0 µA to 50 mA.
Sourced from Process 07.

Absolute Maximum Ratings* TA = 25°C unless otherwise noted

*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.

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.

adhesive layer, sealant, and anti-static sprayed agent.
These reeled parts in standard option are shipped with
3,000 units per 7" or 177cm diameter reel. The reels are
dark blue in color and is made of polystyrene plastic (anti­static coated). Other option comes in 10,000 units per 13"
or 330cm diameter r eel. This and some other options are
described in the Packaging Information table.

These full reels are individually labeled and placed inside
a st andard intermediate made of recyclable corrugated
brown paper with a Fairchild l ogo printing. One pizza box
contains eight reels maximum. And these intermediate
boxes are placed inside a labeled shipping box which
comes in diff erent sizes depending on the number of parts
shipped.
