BC817-40Q-7-F

Overview

The BC817-40Q-7-F is an NPN small signal transistor manufactured by Diodes Incorporated. It features a collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 0.5 A. The device supports a peak pulse collector current (ICM) of 1.0 A and has a maximum power dissipation (PD) of 310 mW at +25°C. It operates within a temperature range of -65°C to +150°C. The DC current gain (hFE) ranges from 250 to 400 at IC = 100 mA, with a transition frequency (fT) of 100 MHz. Packaged in SOT-23, it is AEC-Q101 qualified for automotive applications.

Feature Summary

AEC-Q101 qualified for automotive applications requiring specific change control
Epitaxial planar die construction for reliable switching and amplification
Totally lead-free and fully RoHS compliant green device

Applications

Automotive general-purpose switching circuits
Audio frequency (AF) amplifier stages
General-purpose discrete transistor applications

Procurement Notes

Verify the component against the official Diodes Incorporated datasheet DS38331 Rev. 4-2. Confirm that the marking code K6C corresponds to the BC817-40Q variant. Ensure the package matches the specified SOT-23 dimensions. Validate compliance with RoHS 3 and REACH regulations as stated in the manufacturer's documentation before integration into designs.

Selection Notes

Select this component when high DC current gain between 250 and 400 is required for low-current amplification tasks. The 45 V breakdown voltage suits standard low-voltage logic and signal processing environments. Automotive qualification makes it suitable for systems demanding strict reliability standards and long-term supply stability under IATF 16949 manufacturing conditions.

Part Context

This part belongs to the BC817-xxQ series of NPN transistors designed specifically for automotive markets. It complements the BC807-xxQ PNP series. The 'Q' suffix indicates automotive-grade qualification, while '-7-F' denotes the tape and reel packaging format containing 3,000 units per reel.

Replacement Considerations

BC817-40Q-13-F offers identical electrical characteristics but comes in a 10,000-unit reel size.

FAQ

What is the minimum DC current gain for the BC817-40Q?

The minimum DC current gain (hFE) is 250 when measured at a collector current of 100 mA and a collector-emitter voltage of 1.0 V.

Is the BC817-40Q-7-F suitable for harsh automotive environments?

Yes, it is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities, making it suitable for automotive applications requiring specific change control.
