BC817-40,235

Overview

The Nexperia BC817-40,235 is an NPN general-purpose transistor housed in a SOT23 (TO-236AB) surface-mount package. It supports a maximum collector current of 500 mA and a collector-emitter voltage of 45 V. The device offers a DC current gain range of 250 to 600 at 100 mA. Peak collector current reaches 1 A for single pulses up to 1 ms. Total power dissipation is rated at 250 mW under standard conditions.

Feature Summary

High current capability suitable for demanding switching applications
Defined current gain selection for consistent amplification performance
Compact surface-mount plastic package design

Applications

General-purpose switching circuits
Amplifier stages
Driver circuits

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm exact packaging and reel specifications. Ensure the component version matches the required automotive or non-automotive qualification status before procurement. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity.

Selection Notes

Select this component when a small SMD NPN transistor with high current handling is required. The BC817-40 variant provides a specific current gain band compared to other series options. Evaluate thermal resistance requirements based on the intended PCB footprint and ambient operating temperature constraints.

Part Context

This device belongs to the BC817 series of NPN general-purpose transistors. The series includes variants with different current gain characteristics, such as BC817-16 and BC817-25. All share the same physical package and basic electrical limits, differing primarily in their hFE ranges.

Replacement Considerations

Compatible substitutes include the BC817-40 from Diotec Semiconductor and Micro Commercial Components. Verify pinout compatibility and ensure equivalent voltage and current ratings are met by alternative manufacturers.
