BC817-40LT1G

Overview

The BC817-40LT1G is a general-purpose NPN silicon transistor manufactured by onsemi. It operates with a collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA dc. The device provides a DC current gain (hFE) ranging from 250 to 600 at IC = 100 mA, VCE = 1.0 V. It features a maximum collector-emitter saturation voltage of 0.7 V at IC = 500 mA and IB = 50 mA. The component utilizes an SOT-23 package and is rated for junction temperatures between -65°C and +150°C.

Feature Summary

AEC-Q101 qualified and PPAP capable for automotive applications
Pb-free, halogen free/BFR free, and RoHS compliant construction
Suitable for general-purpose switching and amplification tasks

Applications

General-purpose switching circuits
Amplifier stages in electronic designs
Automotive systems requiring unique site control

Procurement Notes

Verify the specific ordering suffix LT1G corresponds to the required tape and reel packaging configuration. Confirm that the AEC-Q101 qualification status meets project requirements if used in automotive contexts. Ensure the selected variant aligns with the necessary hFE binning specifications for the intended circuit design.

Selection Notes

Select this component when a standard NPN transistor with moderate power dissipation capabilities is required. The BC817-40 variant offers higher current gain compared to lower suffix versions. Consider the SOT-23 footprint constraints and thermal resistance characteristics during layout planning.

Part Context

This part belongs to the BC817 series of general-purpose NPN transistors produced by onsemi. The series includes variants differentiated primarily by their DC current gain ranges. The BC817-40 specifically denotes the highest gain tier within this family, designed for applications demanding efficient signal amplification.
