FCX558TA is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Diodes Incorporated. Its product description is TRANS PNP 400V 0.2A SOT-89-3. Review the specifications below when checking this part for your BOM.
The FCX558TA is a PNP high voltage transistor manufactured by Diodes Incorporated, housed in an SOT-89 surface-mount package. It features a collector-emitter breakdown voltage exceeding -400V and supports a continuous collector current of -200mA with a peak pulse current of -500mA. The device offers excellent DC current gain characteristics up to -100mA and maintains a low saturation voltage below -200mV at -20mA. It operates within a temperature range of -65°C to +150°C and is qualified to AEC-Q101 standards for high reliability.
Verify the specific ordering suffix TA against official Diodes Incorporated documentation to confirm reel quantity and packaging specifications. Ensure compliance with RoHS and halogen-free requirements as defined in the manufacturer's quality definitions. Confirm that the application environment remains within the specified thermal resistance limits for the chosen PCB copper area configuration.
Select this component when designing circuits requiring high voltage isolation with moderate current handling capabilities in a compact surface-mount form factor. Consider the thermal dissipation requirements based on the exposed collector pad layout and copper area available on the printed circuit board. Evaluate the complementary NPN type FCX458 if push-pull configurations are necessary for the design.
