Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'S-AN' corresponds to the required tape-and-reel packaging configuration containing 2,500 pieces per bag. Confirm that the component meets Pb Free standards as specified in the official documentation. Ensure compatibility with the SC-71 footprint during PCB layout validation.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor is needed for applications demanding both high voltage tolerance and significant current handling. The low saturation voltage minimizes power loss during conduction, while the high gain-bandwidth product supports efficient signal amplification at elevated frequencies compared to standard general-purpose transistors.

Single Bipolar Transistors Part Context

This part belongs to the 2SA1709/2SC4489 series manufactured by onsemi. It serves as the NPN counterpart to the PNP 2SA1709, sharing identical electrical ratings and physical dimensions. Both devices are designed for complementary push-pull configurations in audio and power driver circuits.

Single Bipolar Transistors Replacement Considerations

The 2SA1709 is the direct PNP complement within the same series. For replacement purposes, verify pinout alignment and thermal resistance requirements against the original design specifications.
