2N3904H

Single Bipolar Transistors Overview

The Sanyo 2N3904H is a small signal NPN bipolar junction transistor designed for general-purpose applications. It features a collector-emitter breakdown voltage of 40V and a maximum continuous collector current of 200mA. The device operates with a transition frequency of 300MHz and dissipates up to 625mW of power. Packaged in a TO-92-3 through-hole configuration, it serves as a reliable component for low-power electronic circuits requiring standard switching or amplification capabilities.

• High-speed switching capability at 300MHz
• Through-hole TO-92-3 mounting format

Single Bipolar Transistors Applications

• Signal amplification stages
• General-purpose switching circuits
• Driver stage implementations

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as Sanyo's semiconductor assets were acquired by Onsemi. Ensure the part number matches the specific 2N3904H variant from the original Sanyo production line rather than generic equivalents. Confirm the package style is TO-92-3 and check for any ordering suffixes that may indicate specific binning or packaging variations. Request official datasheets to validate electrical parameters against current supply sources.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 40V rating and 200mA current capacity is required. The TO-92-3 package suits prototyping and low-volume manufacturing. Consider thermal dissipation limits of 625mW for circuit design. Verify compatibility with existing PCB footprints before integration. This part is suitable for general electronics where high-frequency performance up to 300MHz is necessary.

Single Bipolar Transistors Part Context

The 2N3904H belongs to the widely used 2N3904 family of small signal transistors. Originally produced by Sanyo, these components are standardized across the industry for basic digital and analog functions. The 'H' suffix typically denotes specific manufacturing lot or packaging details within the Sanyo product line. These transistors remain common replacements in legacy designs and educational electronics projects.

Single Bipolar Transistors Replacement Considerations

Generic 2N3904 transistors from other manufacturers are electrically compatible substitutes. Verify pinout alignment and package dimensions match the TO-92-3 specification. Check that alternative sources meet the 40V and 200A ratings. No functional changes occur with standard cross-brand replacements.
