BC81716MTF

Overview

The Fairchild Semiconductor BC81716MTF is an NPN epitaxial silicon transistor designed for general-purpose switching and amplification applications. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device utilizes a surface-mount SOT-23 package, providing a compact footprint suitable for space-constrained designs. It features three specific current gain selections to facilitate precise circuit tuning without requiring binning variations.

Feature Summary

• NPN epitaxial silicon construction for reliable switching performance
• Compact SOT-23 surface-mount package design
• Three distinct current gain groupings for application flexibility

Applications

• General-purpose switching circuits
• Amplifier stages
• AF-driver stages
• Low power output stages

Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor's semiconductor assets were acquired by ON Semiconductor. Ensure the component source aligns with current supply chain realities. Confirm the specific suffix 'MTF' matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this component when a standard NPN switch is needed in a small form factor. The 45V rating suits low-voltage logic interfaces. Choose the '-16' variant specifically if the target hFE range corresponds to that particular gain bin. Verify thermal management requirements against the SOT-23 package limitations for continuous operation.

Part Context

This part belongs to the widely used BC817 family of NPN transistors. It serves as the complementary counterpart to the BC807 PNP series. The device is engineered for cost-effective mass production in consumer electronics and industrial control boards where small size and adequate current handling are prioritized over high-frequency RF performance.

Replacement Considerations

• BC817-16
• BC817-16Q

FAQ

What does the '16' designation indicate in the model number?

The '16' indicates a specific current gain (hFE) binning selection provided by the manufacturer to ensure consistent amplification characteristics across production batches.

Is this component suitable for high-frequency radio applications?

No, the BC81716MTF is classified as a general-purpose transistor optimized for audio frequency drivers and low-power switching, not high-frequency RF operations.
