2STR1215

Single Bipolar Transistors Overview

The 2STR1215 is a low voltage fast-switching NPN power transistor manufactured by STMicroelectronics. It utilizes PB-HCD (power bipolar high current density) technology to deliver exceptional high gain performance combined with very low saturation voltage. The device is housed in a miniature SOT-23 plastic package designed for surface mounting circuits. Its complementary PNP counterpart is the 2STR2215.

Single Bipolar Transistors Procurement Notes

Verify component status as the 2STR1215 is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing designs using the complementary 2STR2215 PNP transistor. Check datasheet revisions for any specific handling or storage requirements associated with end-of-life components.

Single Bipolar Transistors Selection Notes

Select this NPN transistor when low saturation voltage and high current gain are critical for efficiency. The SOT-23 package suits space-constrained surface mount designs. Consider the complementary 2STR2215 for push-pull or bridge configurations. Verify that the operating conditions remain within the specified limits for fast-switching applications.
