Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as Sanyo semiconductor assets are now managed by onsemi. Confirm that the ordering suffix matches the specific tape-and-reel or bulk packaging requirements. Ensure the component meets RoHS compliance standards if required by the target application. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a low-power, high-speed NPN switch is required in a surface-mount design. The 15 V rating and 0.2 A current limit define its operational boundaries. Consider the thermal constraints of the TO-252 package for power dissipation management. Compare hFE specifications against circuit gain requirements to ensure adequate drive capability.

Single Bipolar Transistors Part Context

This transistor belongs to the 2SC4523 series, which includes variants such as the 2SC4523S-TL-E. These devices are categorized as RF small-signal bipolar transistors intended for general-purpose switching and amplification. The series utilizes standard silicon planar technology optimized for reliability in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Direct substitutes may include other NPN transistors from the same family, such as the 2SC4523 without the suffix, provided pin compatibility and electrical ratings align. Verify package dimensions and thermal characteristics when substituting to ensure mechanical fit and thermal performance remain within acceptable limits.
