FZT790ATC

Single Bipolar Transistors Overview

The FZT790ATC is a PNP silicon planar medium power transistor manufactured by Diodes Incorporated. It features a collector-emitter voltage of -40V and supports a continuous collector current of -3A with a peak pulse current of -6A. The device offers a transitional frequency of 100MHz and a DC current gain of 200 at 1A. Packaged in an SOT-223 (Type DN) housing, it provides very low equivalent on-resistance of 125mΩ at 2A.

Single Bipolar Transistors Feature Summary

• High continuous collector current capability up to 3A with a peak pulse rating of 6A
• Very low saturation voltage and equivalent on-resistance for efficient switching
• High DC current gain of 200 at 1A collector current
• RoHS compliant and halogen-free green device construction

Single Bipolar Transistors Applications

• DC-DC converters
• Siren drivers

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TC' against official Diodes documentation, as standard datasheets list 'ATA'. Confirm package type matches SOT-223 requirements. Ensure design accounts for thermal resistance values based on actual PCB copper area. Validate that application conditions remain within absolute maximum ratings for voltage and current limits.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high current handling in a compact surface-mount package. Consider the complementary NPN type FZT690B if push-pull configurations are needed. Evaluate thermal dissipation capabilities based on the specific PCB layout copper weight and size to ensure operation within safe junction temperature ranges.
