We also provide you with a 2N3904 Datasheet pdf. To download the datasheet just copy and paste the below link in your browser.This article will introduce you to the pinout, model, Introduction, features, specifications, applications, equivalent, and dimensions of the 2N3904 transistor. The storage and operating temperature is from -55☌ and below +150 ☌.Max collector current is 200mA, therefore the derived load should be under 160mA.

The maximum collector to emitter voltage is 40V so do not drive load of more than 32V.Therefore it is advised stay 20% below from its absolute maximum ratings. To get long term performance follow the guidelines below.ĭo not use the transistor to its absolute maximum ratings, using any transistor to its absolute maximum rating may result in internal or external damage to the transistor or decrease its performance. Safe Operating Guidelines / Absolute Maximum Ratings: Other than that it can also be used RF applications around 100MHz. Moreover it can also be used as amplifier and preamplifier in wide variety of applications. When use as a switch it can drive load of upto 200mA. When comparing the two we can say that 2N3904 is the updated version of 2N3903.ĢN3903 is designed to use in general applications hence it can be used in variety of applications which requires small signal transistor. Maximum collector current is 200mA, minimum to maximum DC current gain is from 20 to 150, max noise figure is 6.0dB, maximum transition frequency is 250MHz and max power dissipation is 625mW.ĢN3903 is the transistor of the famous 2N3904 series and it is not exactly same as 2N3904 but can be used as a replacement of 2N3904 in most applications. The max collector to emitter of the transistor is 40V. Like 2N3904 the 2N3903 is also designed for general purpose switching and amplification purposes. It is a transistor from the famous 2N3904 family.

Therefore it is suggested check pinout before replacing.ĢN3903 Transistor Explained / Description:ĢN3903 is an NPN BJT small signal transistor available in TO-92 package.

Pin configuration of these replacement transistors can be different from the 2N3903. Minimum & Maximum DC Current Gain (hFE): 20 to 150.Max Collector-Emitter Voltage (VCE): 40V.
