Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'AG' against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides original manufacturer documentation. Confirm that the TO-204-2 package dimensions match the target PCB or heatsink mounting requirements before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component for linear regulation or switching tasks requiring high current handling. The TO-204-2 package necessitates direct mounting to a heatsink due to the metal tab connection. Consider the 60 V breakdown limit when designing circuits with higher supply voltages or transient spikes.

Single Bipolar Transistors Part Context

The 2N3055 series represents a classic NPN silicon power transistor originally introduced in the 1960s. The onsemi variant maintains the legacy specifications while adhering to modern manufacturing standards. It is frequently paired with complementary PNP devices like the MJ2955 for push-pull configurations in high-fidelity audio and power supply designs.

Single Bipolar Transistors Replacement Considerations

Cross-reference with JAN2N3055 or JANTX2N3055 for military-grade variants if enhanced reliability is required. Verify that alternative manufacturers offer identical TO-204-2 mechanical footprints and compatible electrical parameters such as hFE ranges and saturation voltages.
