MJ2955 PBFREE

Single Bipolar Transistors Overview

The Central Semiconductor MJ2955 PBFREE is a PNP silicon power transistor manufactured using an epitaxial base process and housed in a hermetically sealed TO-3 metal case. It serves as the complementary counterpart to the NPN 2N3055 device. Key electrical ratings include a collector-emitter voltage of 60 V, continuous collector current of 15 A, and power dissipation of 115 W at 25°C. The component operates within a junction temperature range of -65°C to +200°C.

Single Bipolar Transistors Feature Summary

• Complementary PNP silicon power transistor designed for general purpose switching and amplifier applications
• Hermetically sealed metal TO-3 package with high thermal conductivity
• Epitaxial base process construction for robust performance

Single Bipolar Transistors Applications

• General purpose power switching circuits
• Linear amplifier stages
• Audio output amplification

Single Bipolar Transistors Procurement Notes

Verify compliance with RoHS directives by confirming the PBFREE suffix on all orders. Ensure procurement channels are authorized to prevent counterfeit components. Review material composition specifications regarding lead content in die attach solder if specific environmental regulations apply to the final assembly.

Single Bipolar Transistors Selection Notes

Select this component when a high-current PNP solution is required to match the NPN 2N3055 in complementary configurations. Evaluate thermal management requirements carefully, as the 115 W dissipation rating assumes a heatsink maintained at 25°C. Confirm that the TO-3 mechanical footprint fits the target chassis design constraints.

Single Bipolar Transistors Part Context

This device belongs to a family of complementary silicon power transistors produced by Central Semiconductor Corp. It shares the same physical dimensions and mounting style as its NPN pair, facilitating symmetrical circuit layouts. The TO-3 package provides superior heat dissipation compared to plastic encapsulated alternatives.

Single Bipolar Transistors Replacement Considerations

Central Semiconductor has classified the MJ2955 as End of Life (EOL) per notice PDN01250. No direct replacement part numbers are suggested by the manufacturer.
