BCP55TF

Overview

The BCP55TF is an NPN bipolar junction transistor manufactured by Nexperia, housed in a SOT223 (SC-73) surface-mount package. It features a maximum collector-emitter voltage of 80 V and a continuous collector current rating of 1 A. The device includes an integrated base resistor network for simplified circuit design. Key electrical characteristics include a DC current gain (hFE) ranging from 100 to 640 at specified test conditions, a collector-emitter saturation voltage of 500 mV, and a power dissipation capability suitable for general-purpose switching applications.

Feature Summary

• Integrated base resistor network simplifies drive circuitry requirements
• High current gain optimized for efficient switching performance
• Robust thermal handling within the SOT223 surface-mount footprint

Applications

• General-purpose switching circuits
• Driver stages for relays and solenoids
• Logic-to-analog interface buffers

Procurement Notes

Verify the specific suffix 'TF' against the official Nexperia datasheet to confirm tape-and-reel packaging specifications and exact pinout orientation. Ensure compatibility with RoHS and REACH regulatory standards required for your target market. Cross-reference the 12NC code for accurate ordering and supply chain tracking.

Selection Notes

Select this component when a high-gain NPN switch with integrated base resistance is required in a compact SOT223 package. Compare the 80 V breakdown voltage and 1 A current limits against circuit demands. Consider thermal derating curves if operating near maximum power dissipation limits in enclosed environments.

Part Context

This part belongs to Nexperia's BCP series of dual-resistor NPN transistors. It shares functional similarities with the BCX54 and BCX55 families but utilizes the larger SOT223 package for improved heat dissipation compared to smaller SOT-89 or SOT-23 alternatives. The TF suffix typically denotes reel packaging configuration.

Replacement Considerations
