2N4904 Description

Short technical summary and product information.

The 2N4904 is a PNP silicon power transistor manufactured using an epitaxial base process. It is designed for general purpose amplifier and switching applications. This transistor offers key electrical parameters including a maximum collector-emitter voltage (V CEO max) of -40V and a maximum collector current (I C max) of -5A.

 

With a maximum power dissipation (P TOT max) of 87W at 25°C in free air, and a junction temperature (T J max) of 200°C, the 2N4904 is suitable for demanding applications. Its DC current gain (h FE) ranges from 25 to 100 at an I C of -2.5A. The transistor is housed in a TO-3 package, typically mounted through hole.

 

This device is part of a series providing complementary operation, with related PNP devices like the 2N4905 and 2N4906, and NPN counterparts such as the 2N4913, 2N4914, and 2N4915.
