Overview
The BCV49TA is a 60V NPN Darlington transistor in an SOT89 package. It offers high continuous collector current of 500mA and peak pulse current of 800mA. The device features a minimum DC current gain (hFE) of 2,000 at IC=100µA, up to 10,000 at IC=100mA. Collector-emitter saturation voltage is typically 1.0V at IC=100mA. Transition frequency is 170MHz. Operating temperature range is -55°C to +150°C. Power dissipation is 1.1W on 15mm x 15mm copper or 1.5W on 25mm x 25mm copper.
Feature Summary
- High current gain exceeding 10k at 100mA collector current
- Qualified to AEC-Q101 standards for automotive reliability
- Totally lead-free and fully RoHS compliant construction
Applications
- Automotive relay driver circuits
- High-gain switching applications
- Power control modules requiring high input impedance
Procurement Notes
Verify the specific ordering suffix TA corresponds to the 3,000-unit reel quantity as documented in the manufacturer's ordering information table. Confirm that the EG marking code matches the intended product type identification for quality assurance purposes during incoming inspection.
Selection Notes
Select this component when a single NPN Darlington configuration is required to drive loads up to 500mA with minimal base drive current. Ensure the application operates within the 60V collector-emitter voltage limit and utilizes the SOT89 package thermal characteristics for adequate heat dissipation under steady-state conditions.
Part Context
This part belongs to Diodes Incorporated's line of medium-power voltage regulator diodes and transistors. The BCV49 series provides complementary PNP options like the FCX705. It is designed for general regulation functions and high-reliability environments, distinguishing itself through its specific Darlington topology and automotive qualification status.
Replacement Considerations
Check for direct substitutes such as the Nexperia BCV49,115 which shares similar electrical parameters and UPAK/SOT89 form factors. Verify pinout compatibility and thermal resistance values before swapping manufacturers to ensure circuit performance remains unchanged.
