Central Semiconductor Corp. Single Bipolar Transistors 2N2405 TIN/LEAD

The 2N2405 is a silicon NPN epitaxial planar transistor in a TO-39 package for small signal switching applications. It has a collector-emitter voltage rating of 90 V, a continuous collector current of 1.0 A, and a power dissipation of 1.0 W. The device operates with a junction temperature range of -65 to +200 °C. Current gain (hFE) ranges from 20 to 200 depending on operating conditions. The transition frequency is 120 MHz at 50 mA collector current. The TO-39 package defines the pinout as emitter, base, collector. The part meets standard operational limits for silicon transistors without specific qualifications cited.
