Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against official Diodes Incorporated documentation before procurement. Confirm that the 'TC' suffix aligns with the required reel size, tape width, and quantity per reel specifications found in the datasheet's ordering information section. Ensure compliance with RoHS and halogen-free requirements if applicable to your manufacturing process.

Single Bipolar Transistors Selection Notes

Select this component when a high-current NPN transistor with low saturation voltage is required in a surface-mount SOT223 package. Consider its complementary PNP type, the FZT955, if a matched pair is needed for push-pull configurations. Evaluate thermal resistance values based on the specific PCB copper coverage and mounting conditions used in your design.

Single Bipolar Transistors Part Context
