LS303
MONOLITHIC DUAL
NPN TRANSISTOR
Linear Systems High Voltage Super-Beta Monolithic Dual NPN
FEATURES
HIGH GAIN
The LS303 is a monolithic pair of high voltage Super-
hFE ≥ 2000 @ 1µA TYP.
COBO ≤ 2.0pF
|VBE1 – VBE2 |= 0.2mV TYP.
100MHz
Beta NPN transistors mounted in a single TO-78
package. The monolithic dual chip design reduces
parasitics and gives better performance while ensuring
extremely tight matching.

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.
