MMBT3904HLT1G is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS NPN 40V 0.2A SOT23. Review the specifications below when checking this part for your BOM.
The onsemi MMBT3904HLT1G is an NPN silicon bipolar junction transistor housed in a surface-mount SOT-23 package. It supports a maximum DC collector current of 200 mA and a collector-emitter voltage (VCEO) of 40 V, with a collector-base voltage (VCBO) of 60 V and emitter-base voltage (VEBO) of 6 V. The device features a gain-bandwidth product (fT) of 300 MHz and a total power dissipation of 225 mW. It operates within a temperature range of -55 °C to +150 °C.
Verify the specific suffix 'H' indicates automotive qualification and PPAP compliance. Confirm that the datasheet matches the manufacturer's official documentation for the MMBT3904HL series. Ensure the component meets environmental requirements such as halogen-free status. Cross-reference the ordering part number with the manufacturer's latest catalog to confirm availability and specifications.
Select this component when automotive certification and PPAP are mandatory for the design. The SOT-23 package offers compact sizing for space-constrained layouts. Consider the 225 mW power dissipation limit and thermal resistance characteristics for heat management. Verify compatibility with the required operating temperature range of -55 °C to +150 °C.
This part belongs to the MMBT3904L family of general-purpose NPN transistors. The 'H' prefix specifically denotes automotive-grade variants designed for rigorous quality standards. It shares electrical characteristics with standard MMBT3904 devices but includes additional manufacturing controls and certifications required for automotive applications.
Standard MMBT3904LT1G lacks automotive certification. MMBT3904WT1G uses SC-70 packaging. Verify pinout compatibility before substitution.
