Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the 2SC2911 part number was originally associated with Sanyo Semicon Device. Confirm that the specific suffix 'S' denotes the correct package or variant from onsemi's current portfolio. Check RoHS compliance status and ensure the datasheet matches the exact component revision before integration into designs.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor is required for AF predriver stages. Ensure the design accommodates the 160V breakdown voltage and 140mA current limits. Verify thermal management requirements for 100W application contexts. Compare against other high-voltage switching transistors if lower voltage ratings suffice for the specific circuit topology.

Single Bipolar Transistors Part Context

This component belongs to the family of high-voltage switching transistors used in audio and power control systems. Originally developed by Sanyo, these devices are now often managed by onsemi following industry acquisitions. The 2SC2911 series is specifically engineered for robustness in high-voltage, medium-current switching scenarios typical of audio amplifier predrivers.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include 2SA1209, 2SA1477, and 2SA1606. These alternatives share similar high-voltage switching characteristics and are suitable for comparable predriver applications. Verify pinout compatibility and electrical parameters before substitution.
