2SD1805G-TL-E

Single Bipolar Transistors Overview

The onsemi 2SD1805G-TL-E is an NPN silicon bipolar junction transistor housed in a TP-FA (TO-252) surface-mount package. It features a collector-to-emitter voltage of 20V and a continuous collector current rating of 5A. The device offers a minimum DC current gain (hFE) of 95 at 3A, with a typical gain range of 280 to 560 at 500mA. Key electrical parameters include a collector cutoff current of 100nA, a gain-bandwidth product of 120MHz, and a collector dissipation of 1W at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific 'G' ranking suffix corresponds to the required hFE gain band (280 to 560 at IC=500mA). Confirm the 'TL-E' designation matches the TP-FA tape-and-reel packaging format containing 700 pieces per reel. Ensure the component meets Pb-Free requirements as specified in the ordering information section of the datasheet.

Single Bipolar Transistors Selection Notes

Select this component when a low VCE(sat) and fast switching speed are critical for the application. The TO-252 package provides a balance between thermal performance and space efficiency compared to through-hole alternatives. Consider the 20V breakdown voltage limit and ensure the operating conditions remain within the recommended operating limits to maintain reliability.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1805 series of single NPN transistors manufactured by onsemi. The series includes variants with different gain rankings (F and G) and packaging options (TP bulk bags and TP-FA reels). The 2SD1805G-TL-E specifically utilizes the TP-FA package and the higher gain G-rank classification.
