MPSA42-BP

Single Bipolar Transistors Overview

The MPSA42-BP is an NPN silicon high voltage transistor manufactured by Micro Commercial Components (MCC). It features a maximum collector-emitter voltage of 300 V and a continuous collector current rating of 300 mA. The device operates within a junction temperature range of -55°C to +150°C and provides a power dissipation capacity of 625 mW at 25°C case temperature. Electrical characteristics include a minimum DC current gain (hFE) ranging from 25 to 80 depending on the specific bin, with a transition frequency of 50 MHz.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix '-BP' corresponds specifically to bulk packaging containing 100,000 pieces per carton as defined in the official MCC documentation. Confirm RoHS compliance status through the 'P' suffix designation mentioned in the datasheet. Ensure procurement channels are authorized distributors to guarantee genuine parts and full traceability according to manufacturer guidelines.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN transistor requires a 300 V collector-emitter breakdown voltage and moderate current handling up to 300 mA. The TO-92 package is appropriate for through-hole mounting where space allows. Consider the thermal resistance values for heat dissipation planning in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the MPSA42/MPSA43 series of high voltage transistors produced by Micro Commercial Components. The MPSA42 variant specifically denotes the NPN configuration, while the MPSA43 serves as its PNP complement. Both devices share similar physical dimensions and electrical profiles tailored for telephone and high voltage switching systems.

Single Bipolar Transistors Replacement Considerations

The MPSA43 is the complementary PNP device within the same series. Other manufacturers produce equivalent NPN high voltage transistors such as the Nexperia PXTA42 or UNISONIC TECHNOLOGIES MPSA42G-T92-K, though pinouts and exact parameters should be verified against specific datasheets before substitution.
