MPSA25 TIN/LEAD is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is 500MA 40V TH TRANSISTOR-SMALL SI. Review the specifications below when checking this part for your BOM.
The MPSA25 TIN/LEAD is a single NPN Darlington transistor manufactured by Central Semiconductor. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. The device features a collector-emitter voltage (VCEO) of 40 V and a collector-base voltage (VCBO) of 40 V. It supports a continuous collector current of 100 mA with a power dissipation rating of 625 mW. The emitter-base breakdown voltage (VEBO) is specified at 10 V. The component operates within a temperature range of -65°C to +150°C.
Verify the specific ordering suffix for lead content compliance. Confirm that the TO-92-3 package matches the target PCB footprint. Ensure thermal management aligns with the 625 mW dissipation limit under expected operating conditions. Check RoHS status documentation for regulatory requirements.
Select this component when high current gain is required from a small signal input. The TO-92-3 package suits through-hole assembly processes. Verify that the 40 V voltage rating meets circuit requirements. Consider the 100 mA current limit for load handling capabilities.
This part belongs to the MPSA25 series of NPN Darlington transistors produced by Central Semiconductor. It is designed for general-purpose amplification and switching tasks where high sensitivity is necessary. The tin/lead variant indicates specific terminal plating characteristics distinct from lead-free alternatives.
MPSA25APM PBFREE serves as a lead-free alternative within the same product family.
