FZT605TC

Single Bipolar Transistors Overview

The FZT605TC is a single NPN Darlington transistor manufactured by Diodes Incorporated, housed in an SOT223 (Type DN) surface-mount package. It features a collector-emitter breakdown voltage of 120V and a collector-base breakdown voltage exceeding 140V. The device supports a continuous collector current of 1.5A with a peak pulse current capability of 4A. DC current gain is specified at a minimum of 2,000 at 1A and up to 5,000 at 500mA. Thermal performance includes a junction-to-ambient resistance of 41.7°C/W on a standard 50mm x 50mm FR4 board.

Single Bipolar Transistors Feature Summary

• High current handling capability with 1.5A continuous collector current rating
• Elevated voltage tolerance with over 120V collector-emitter breakdown
• High DC current gain ensuring efficient drive requirements
• Lead-free and halogen-free construction compliant with environmental directives

Single Bipolar Transistors Applications

• Lamp driving circuits
• Relay control modules
• Solenoid actuation systems

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TC against official documentation to confirm the 4,000-unit reel packaging configuration. Ensure that design implementations account for the thermal resistance variations dependent on copper pad layout dimensions and PCB material specifications as detailed in the datasheet.

Single Bipolar Transistors Selection Notes

Select this component when high gain and moderate power dissipation are required in a compact surface-mount form factor. Evaluate the thermal characteristics carefully based on the target PCB copper area, as power dissipation ratings vary significantly between 50mm and 25mm copper footprints.

Single Bipolar Transistors Part Context

This part belongs to the FZT605 series of NPN Darlington transistors designed for general-purpose switching and amplification. The 'TC' suffix specifically denotes the tape-and-reel packaging format containing 4,000 units per carrier, distinguishing it from the TA variant which contains 1,000 units.

Single Bipolar Transistors Replacement Considerations

Consult official manufacturer cross-reference lists for verified substitutes. Do not assume functional equivalence with other Darlington packages without verifying pinout compatibility and absolute maximum ratings.
