Overview
The BCX19TA is a single NPN silicon bipolar junction transistor manufactured by Diodes Incorporated. It is housed in an SOT-23-3 surface-mount package and designed for general-purpose switching and amplification applications. The device supports a maximum collector current of 500 mA and withstands a collector-emitter voltage (VCEO) of 45 V, with a collector-base voltage (VCBO) of 60 V and an emitter-base voltage (VEBO) of 7 V. Power dissipation is rated at 330 mW, and the transition frequency (fT) reaches 200 MHz. Operating temperatures range from -55°C to +150°C.
Feature Summary
- High-frequency performance with a transition frequency of 200 MHz suitable for signal processing
- Robust voltage handling capabilities with 45 V collector-emitter rating
- Compact SOT-23-3 surface-mount packaging for automated assembly integration
Applications
- General-purpose low-power switching circuits
- Small-signal amplification stages
- Consumer electronics signal processing
Procurement Notes
Verify component lifecycle status prior to procurement as the BCX19TA may be classified as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors and assess lead times carefully. Ensure that any substitute components meet identical electrical specifications and thermal requirements to maintain circuit integrity without requiring redesign.
Selection Notes
Select this component for applications requiring moderate voltage isolation and high-speed switching within a compact footprint. Evaluate thermal management needs given the 330 mW power dissipation limit in small packages. Compare against alternative NPN transistors offering similar gain characteristics and voltage ratings if supply constraints exist for this specific part number.
Part Context
The BCX19TA belongs to the single bipolar transistor category from Diodes Incorporated, utilizing standard silicon technology. It serves as a discrete active component within broader semiconductor portfolios targeting consumer and industrial markets. The SOT-23-3 form factor aligns with industry standards for space-constrained printed circuit board layouts.
Replacement Considerations
Similar available substitutes include the BC817-16-7-F from Diodes Incorporated. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official datasheets for both original and replacement parts to ensure functional equivalence in the target application environment.
