Overview
The BCX6825TA is a 20V NPN silicon planar medium power transistor manufactured by Diodes Incorporated. It features a maximum continuous collector current of 1A and a collector-emitter breakdown voltage (BVCEO) of 20V. The device offers low saturation voltage, typically less than 500mV at 1A, and a transitional frequency of 100MHz. It is housed in an SOT-89 surface-mount package with a maximum power dissipation of 1W and operates within a temperature range of -65°C to +150°C.
Feature Summary
- High current capability supporting up to 1A continuous collector current
- Low saturation voltage for efficient switching performance
- Qualified to AEC-Q101 standards for high reliability applications
Applications
- Power MOSFET gate driving
- Low loss power switching
Procurement Notes
Verify the specific ordering suffix when purchasing. The 'TA' suffix indicates commercial grade packaging on a reel. Ensure the required variant matches the application's environmental and reliability needs, as automotive-grade options utilize a different suffix designation.
Selection Notes
Select this component for circuits requiring a single NPN transistor with a 20V collector-emitter rating and 1A current handling capacity. Consider the SOT-89 package dimensions and thermal resistance characteristics during PCB layout design to ensure adequate heat dissipation under load conditions.
Part Context
This part belongs to the BCX68 product line from Diodes Incorporated. It serves as the NPN counterpart to the complementary BCX69 PNP transistor. The series is designed for general-purpose medium power switching applications where low saturation voltage and reliable operation are required.
Replacement Considerations
BCX6825QTA is the automotive-grade equivalent within the same family. Verify that any substitute maintains the 20V BVCEO, 1A IC rating, and SOT-89 footprint compatibility.
FAQ
What is the DC current gain (hFE) at 500mA?
The minimum DC current transfer ratio (hFE) is 160 when tested at IC = 500mA and VCE = 1V.
Is this component suitable for automotive use?
The standard BCX6825TA is commercial grade. For automotive applications, the BCX6825QTA variant is available, which is qualified to AEC-Q101 standards.
