MPSW51A-AP

Single Bipolar Transistors Overview

The MPSW51A-AP is a PNP plastic-encapsulated transistor manufactured by Micro Commercial Components (MCC). It operates within a collector-emitter voltage range of -40 V and supports a continuous collector current of -1 A. The device features a maximum power dissipation of 625 mW at 25°C ambient temperature and a thermal resistance of 200 °C/W junction to ambient. Electrical characteristics include a collector-base breakdown voltage of -50 V, an emitter-base breakdown voltage of -5 V, and a transition frequency of 50 MHz. The component utilizes a TO-92 package with straight leads.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official MCC documentation to confirm packaging type and compliance status. The MPSW51A-AP designation indicates ammo packing. Ensure procurement channels are authorized distributors to guarantee part authenticity and traceability. Confirm that the requested variant matches the required halogen-free specifications if applicable, as this may require a distinct suffix.

Single Bipolar Transistors Selection Notes

Select the MPSW51A-AP when a PNP transistor with -1 A continuous current capability and -40 V voltage ratings is required. Consider the TO-92 package constraints for thermal management, noting the 200 °C/W thermal resistance. Evaluate the DC current gain requirements against the specified minimums at relevant collector currents. Ensure the application environment stays within the -55°C to +150°C operating junction temperature limits.

Single Bipolar Transistors Part Context

This component belongs to the standard plastic-encapsulated transistor family produced by Micro Commercial Components. It serves as a discrete semiconductor solution for general electronic designs. The MPSW51A variant specifically addresses applications needing moderate current handling in a compact through-hole form factor. It is distinct from higher-power or surface-mount alternatives within the manufacturer's portfolio.

Single Bipolar Transistors Replacement Considerations

Consult official MCC substitution guides for verified equivalents. Generic replacements must match the PNP configuration, TO-92 package, and electrical ratings including -40 V VCEO and -1 A IC.
