LM3146 High Voltage Transistor Array

General Description

The LM3146 consists of five high voltage general purpose

silicon NPN transistors on a common monolithic substrate

Two of the transistors are internally connected to form a

differentially-connected pair The transistors are well suited

to a wide variety of applications in low power system in the

dc through VHF range They may be used as discrete tran-

sistors in conventional circuits however in addition they

provide the very significant inherent integrated circuit ad-

vantages of close electrical and thermal matching The

LM3146 is supplied in a 14-lead molded dual-in-line pack-

age for applications requiring only a limited temperature

range
