FZT603TC

Single Bipolar Transistors Overview

The FZT603TC is an NPN Darlington transistor manufactured by Diodes Incorporated, housed in a SOT-223 package. It features a collector-emitter voltage (VCEO) of 80 V and a continuous collector current (IC) of 2 A. The device supports a peak pulse current of 6 A and operates within a temperature range of -55°C to +150°C. Electrical characteristics include a DC current gain (hFE) ranging from 2,000 to 5,000 at IC = 2A, and a transition frequency (fT) of 150 MHz.

Single Bipolar Transistors Feature Summary

• High current handling capability with a 2 A continuous collector rating and 6 A peak pulse support.
• Elevated breakdown voltages exceeding 80 V for collector-emitter and 100 V for collector-base configurations.
• Optimized for high reliability applications through qualification to JEDEC standards and automotive references.
• Environmentally compliant construction utilizing lead-free finishes and halogen-free molding compounds.

Single Bipolar Transistors Applications

• High-current switching circuits requiring elevated isolation voltages
• Automotive-grade power control modules
• Industrial load drivers and relay interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TC' against official manufacturer documentation, as standard datasheets primarily list 'TA'. Confirm that the requested variant matches the exact mechanical dimensions and marking codes defined in the FZT603 series specifications before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits necessitating high DC current gain combined with robust thermal performance. Ensure adequate heat sinking is implemented to manage power dissipation effectively, particularly under continuous load conditions near the maximum rated limits.
