BC817-25FSW-7

Overview

The BC817-25FSW-7 is a 45V NPN small signal transistor manufactured by Diodes Incorporated. It features a continuous collector current of 500mA and is housed in a U-DFN1412-3/SWP (Type A) package with a low-profile height of 0.6mm. The device provides a DC current gain range of 160 to 400 at IC=100mA and VCE=1V, with a transition frequency of 100MHz. It supports an operating temperature range from -55°C to +150°C and includes sidewall tin plating for wettable flanks.

Feature Summary

• Low-profile 0.6mm-high package designed for thin applications
• Sidewall tin plating facilitates wettable flanks for automated optical inspection
• Totally lead-free and fully RoHS compliant construction

Applications

• General-purpose switching
• Amplification circuits

Procurement Notes

Verify the specific ordering suffix matches the required reel size and tape width configuration. Confirm that the U-DFN1412-3/SWP package dimensions align with the target PCB footprint. Ensure compliance with moisture sensitivity level 1 requirements during storage and handling procedures.

Selection Notes

Select this component when a compact surface-mount solution is required for high-current switching tasks. The 500mA rating and 45V breakdown voltage suit general-purpose amplifier designs. Consider the sidewall tin plating if automated optical inspection reliability is critical for the manufacturing process.

Part Context

This part belongs to the BC817 series of NPN silicon transistors produced by Diodes Incorporated. It shares functional similarities with other variants like the BC817-16FSW and BC817-40FSW, distinguished primarily by their DC current gain specifications. The series utilizes the same U-DFN1412-3/SWP package form factor.

Replacement Considerations

Direct substitutes include BC817-16FSW-7 and BC817-40FSW-7 from the same manufacturer family. Cross-manufacturer equivalents must match the U-DFN1412-3/SWP package and electrical ratings.
