BC817-40W/MIF

Overview

The Nexperia BC817-40W/MIF is an NPN general-purpose transistor housed in a SOT323 (SC-70) surface-mount package. It supports a maximum collector current of 500 mA and a collector-emitter voltage of 45 V. The device features a DC current gain range of 250 to 600 at IC = 100 mA and VCE = 1 V. Peak collector current reaches 1 A for single pulses up to 1 ms. Total power dissipation is rated at 200 mW at Tamb ≤ 25 °C, with a junction temperature limit of 150 °C.

Feature Summary

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

Applications

General-purpose switching circuits
Signal amplification stages
Driver applications for low-power loads

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm manufacturing site codes and reel specifications. Confirm that the component meets non-automotive qualification standards as indicated in the latest datasheet revision. Ensure compatibility with standard reflow soldering profiles for the SOT323 package before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN transistor with high current gain is required for space-constrained designs. The BC817-40W variant provides a guaranteed minimum hFE of 250, distinguishing it from lower-gain series options. Evaluate thermal resistance requirements based on PCB copper area and ambient operating conditions to ensure reliable operation within specified limits.

Part Context

This part belongs to the BC817W series, which includes variants with different current gain ranges such as BC817W, BC817-16W, and BC817-25W. All series members share the same SOT323 package and electrical ratings except for the hFE binning. The PNP complement for this family is the BC807-40W.

Replacement Considerations

Direct substitutes include other manufacturers' NPN transistors in the SOT-323 package with matching 45V/500mA ratings and comparable hFE ranges. Verify pinout compatibility and thermal characteristics before substitution.

FAQ

Is the BC817-40W automotive qualified?

No, the product data sheet indicates that this specific series is not automotive qualified. Customers requiring automotive-grade components should consult Nexperia for alternative -Q product options.
