2N2918

Bipolar Transistor Arrays Overview

The Central Semiconductor Corp 2N2918 is a dual silicon NPN transistor featuring two individual chips mounted in a hermetically sealed TO-78 metal case. Designed for differential amplifier applications, it provides matched electrical characteristics between the internal transistors. Key maximum ratings include a collector-base voltage of 45 V, a collector-emitter voltage of 45 V, and an emitter-base voltage of 6.0 V. The device supports a continuous collector current of 30 mA with power dissipation up to 500 mW at ambient temperature or 1.5 W at a case temperature of 25°C. It operates within a junction temperature range of -65°C to +200°C.
