Texas Instruments LM3046M/NOPB Pent NPN Transistor, 50 mA, 15 V, 14-Pin SOIC

Five general purpose transistors which may be used as discrete transistors in conventional circuits; however, they provide the inherent integrated circuit advantages of close electrical and thermal matching for use in temperature compensated amplifiers.

5 NPN transistors on a common substrate, two connected internally as a differential pair.
Two pairs have matched Vbe within ±5mV (typically ±0.5mV)
Suitable for signal processing, switching systems etc. d.c. to 120 MHz
