Single Bipolar Transistors Procurement Notes

Verify the obsolete status of this component before initiating any procurement process. Confirm availability through authorized distributors or secondary market suppliers, as standard manufacturing supply may be discontinued. Ensure that the specific TO-264 package variant matches the required mechanical footprint for the target application design.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high voltage handling and significant current capacity in linear amplifier configurations. Consider the thermal resistance characteristics and the necessity for adequate heat sinking to manage the 220 W dissipation rating. Evaluate the complementary 2STA2121 PNP transistor if a push-pull topology is required for the circuit design.

Single Bipolar Transistors Part Context

This part belongs to STMicroelectronics' discrete power transistor portfolio, specifically utilizing BiT-LA technology designed for linear amplifier performance. It serves as the NPN counterpart to the 2STA2121 PNP transistor, facilitating balanced complementary pairs for high-fidelity audio and power conversion circuits.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly identifies the 2STA2121 as the complementary device. No other direct substitute part numbers are documented in the official specifications.
