LS318 MONOLITHIC DUAL NPN TRANSISTOR Linear Systems Log Conformance Monolithic Dual NPN The LS318 is a monolithic pair of NPN transistors mounted in a single TO-71 package. The monolithic dual chip design reduces parasitics and is ideal for use in logging applications. See LS358 for PNP. FEATURES LOG CONFORMANCE ABSOLUTE MAXIMUM RATINGS 1 @ 25°C (unless otherwise noted) The hermetically sealed TO-71 is well suited for hi-rel and harsh environment applications. Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation (One side) Continuous Power Dissipation (Both sides) Linear Derating factor (One side) Linear Derating factor (Both sides) Maximum Currents Collector Current (See Packaging Information).

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.
