BC817-40R13

Overview

The Diotec Semiconductor BC817-40R13 is a surface-mount NPN bipolar junction transistor housed in an SOT-23 (TO-236) package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current rating of 800 mA. The device belongs to the -40 gain group, providing a DC current gain range of 250 to 630 at 100 mA. Key electrical parameters include a transition frequency of 100 MHz, a power dissipation capacity of 310 mW, and a collector-emitter saturation voltage of 0.7 V at 500 mA.

Feature Summary

• Offers three distinct current gain groups for precise amplification control
• Compliant with RoHS directives without exemptions
• Adheres to REACH regulations and conflict mineral standards

Applications

• Signal processing circuits
• General switching applications
• Amplification stages

Procurement Notes

Verify that the specific R13 suffix corresponds to the required tape-and-reel packaging configuration. Confirm compliance requirements against the official datasheet before finalizing procurement specifications. Ensure the ordering code matches the exact gain bin and package type intended for the design.

Selection Notes

Select this component when a high-gain NPN transistor is required for low-power surface-mount designs. The -40 designation ensures suitability for applications demanding higher amplification factors compared to lower gain variants. Verify thermal management capabilities given the 310 mW power dissipation limit in the small SOT-23 footprint.

Part Context

This part belongs to the BC817 series of general-purpose SMD NPN transistors manufactured by Diotec Semiconductor. The series provides complementary PNP options and various gain groupings to accommodate different circuit requirements within standard industrial and commercial applications.
