MPSD04 TIN/LEAD is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is 300MA 25V TH TRANSISTOR-SMALL SI. Review the specifications below when checking this part for your BOM.
The MPSD04 TIN/LEAD is an NPN Darlington bipolar junction transistor manufactured by Central Semiconductor Corp. It features a 300 mA collector current, 100 MHz transition frequency, and 625 mW power dissipation. The device utilizes a TO-92-3 through-hole package with tin/lead solder finish.
Verify the specific ordering suffix to confirm the tin/lead composition, as lead-free alternatives may exist within the same product family. Ensure the procurement documentation explicitly references the MPSD04 part number to avoid substitution errors with similar Darlington transistors from other manufacturers or different pin configurations.
Select this component when high current gain is required in a low-power application. The TO-92-3 package suits prototyping and low-volume production. Consider thermal management constraints due to the 625 mW rating. Verify that the tin/lead finish aligns with assembly process requirements before finalizing the design.
