BC817K-25-TP

Overview

The BC817K-25-TP is an NPN silicon general-purpose bipolar junction transistor manufactured by Micro Commercial Components. It operates with a maximum collector-emitter voltage of 45V and a continuous collector current of 500mA. The device features a DC current gain (hFE) range of 100 to 250 at a collector current of 100mA. It is housed in a surface-mount SOT-23 package, designed for low power dissipation applications up to 300mW, and supports an operating temperature range from -55°C to +150°C.

Feature Summary

NPN silicon construction optimized for general-purpose switching and amplification tasks
High DC current gain configuration ensuring reliable signal control
Surface-mount SOT-23 packaging for compact circuit board integration

Applications

General-purpose signal switching circuits
Low-power amplifier stages
Driver circuits for logic interfaces

Procurement Notes

Verify the specific suffix 'K' corresponds to the required hFE binning for your design, as gain ranges vary across the BC817 family. Confirm the SOT-23 footprint matches your PCB layout constraints. Ensure the 500mA current rating and 300mW power dissipation limits are sufficient for your thermal management strategy under expected load conditions.

Selection Notes

Select this component when a standard NPN transistor with moderate gain and 45V breakdown is required in a small surface-mount form factor. Compare against other BC817 variants if higher current handling or different gain thresholds are needed. Verify compatibility with existing SOT-23 footprints and ensure the thermal characteristics meet the application's power dissipation requirements.

Part Context

This part belongs to the BC817 series of NPN silicon transistors widely used in consumer electronics and industrial controls. The series offers various gain grades and voltage ratings within the same physical package family, allowing designers to maintain consistent board layouts while adjusting electrical performance parameters for specific circuit needs.
