LS3550A
MONOLITHIC DUAL
PNP TRANSISTOR
Linear Systems Monolithic Dual PNP Transistor
The LS3550A is a monolithic pair of PNP transistors
mounted in a single TO-78 package. The monolithic
dual chip design reduces parasitics and gives better
performance while ensuring extremely tight matching.
The hermetically sealed TO-78 is well suited for hi-rel
and harsh environment applications.
(See Packaging Information).

Notes:
1. Absolute Maximum ratings are limiting values above which serviceability may be impaired
2. The reverse base‐to‐emitter voltage must never exceed 6.2 volts; the reverse base‐to‐emitter current must never exceed 10µA.
