BCP55-16T-QF

Overview

The BCP55-16T-QF is an NPN medium power transistor from Nexperia, rated for 80 V collector-emitter voltage and 1 A continuous collector current. It is housed in a SOT223 (SC-73) surface-mount package. The device features three current gain selections, with the -16 suffix indicating a specific high-gain bin. It offers high power dissipation capability and is designed for applications requiring robust switching and amplification performance.

Feature Summary

• High collector current capability for efficient load handling
• Three distinct current gain selections to match circuit requirements
• High power dissipation capability within a compact SMD package

Applications

• Linear voltage regulators
• MOSFET drivers
• High-side switches
• Power management circuits
• Amplifiers

Procurement Notes

Verify the exact datasheet revision and electrical characteristics against the official Nexperia documentation before finalizing the design. Confirm that the SOT223 package dimensions and thermal resistance values meet the specific PCB layout and cooling constraints of the target application.

Selection Notes

Select this component when an NPN transistor with 80 V rating and 1 A current capacity is required in a SOT223 package. The -16 suffix denotes a specific current gain range; ensure this matches the biasing needs. Consider the exposed pad thermal performance for heat dissipation in dense layouts.

Part Context

This part belongs to Nexperia's medium power transistor series, offering a balance of performance and packaging flexibility. It serves as a complement to PNP devices like the BCP53 series, enabling push-pull configurations in power management and driver stages.

Replacement Considerations

Direct substitutes include other 80 V, 1 A NPN transistors in SOT223 packages. Verify pinout compatibility and thermal characteristics. Check if alternative gain bins are acceptable for the specific circuit design.
