BD911

Single Bipolar Transistors Overview

The BD911 is a silicon Epitaxial-Base NPN power transistor manufactured by STMicroelectronics. It is housed in a JEDEC TO-220 plastic package and designed for power linear and switching applications. The component belongs to a complementary pair series, with the BD910 serving as its PNP counterpart.

Single Bipolar Transistors Feature Summary

• Utilizes silicon epitaxial-base construction for robust power handling capabilities.

Single Bipolar Transistors Applications

• Power linear circuits
• Switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering code against official STMicroelectronics documentation to ensure correct package type and electrical specifications. Confirm that the required complementary PNP device (BD910) is sourced separately if a push-pull configuration is needed. Check for any recent product lifecycle changes or alternative recommendations on the manufacturer's website.

Single Bipolar Transistors Selection Notes

Select this component when an NPN power transistor in a TO-220 package is required for linear or switching tasks. Consider the complementary BD910 PNP transistor if a matched pair is necessary for the circuit design. Ensure thermal management solutions are adequate for the intended power dissipation levels.

Single Bipolar Transistors Part Context

The BD911 is part of a family of complementary silicon power transistors from STMicroelectronics. It pairs with the BD910 (PNP), while the BD909 and BD912 represent other variants within the broader low-voltage power transistor range. These devices are categorized under preferred sales types for general power applications.
