Silicon NPN Planar RF Transistor
Description
The main purpose of this bipolar transistor is broad-
band amplification up to 1 GHz. In the space-saving
3-pin surface-mount SOT-490 package electrical per-
formance and reliability are taken to a new level cov-
ering a smaller footprint on PC boards than previous
packages. In addition to space savings, the SOT-490
provides a higher level of reliability than other 3-pin
packages, such as more resistance to moisture. Due
to the short length of its leads the SOT-490 is also
reducing package inductances resulting in some bet-
ter electrical performance. All of these aspects make
this device an ideal choice for demanding RF applica-
tions.
