Overview
The BD680ASTU is a PNP power Darlington transistor manufactured by Fairchild Semiconductor. It utilizes planar base island technology with a monolithic Darlington configuration and features an integrated antiparallel collector-emitter diode. The device is housed in a TO-252 (DPAK) surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage of 100 V, a continuous collector current of 4 A, and a maximum power dissipation of 40 W. The DC current gain (hFE) ranges from 750 to 3000 at IC = 2 A, with a minimum guaranteed value of 750.
Feature Summary
- Monolithic Darlington configuration with integrated antiparallel collector-emitter diode
- High current gain linearity for improved signal fidelity
- Planar base island technology construction
Applications
- High-side switching applications
- Power amplifier stages
- Motor control circuits
Procurement Notes
Verify the manufacturer marking on the component body to confirm Fairchild Semiconductor origin, as multiple vendors produce equivalent Darlington transistors. Ensure the suffix 'ASTU' corresponds to the specific tape-and-reel packaging variant required for automated assembly processes. Cross-reference the date code against the manufacturer's lifecycle status to ensure availability and compliance with RoHS directives.
Selection Notes
Select this component when a high-current PNP switching solution is required in a surface-mount form factor. The integrated flyback diode simplifies circuit design for inductive loads such as motors or relays. Consider the thermal resistance of the TO-252 package and implement adequate PCB copper area for heat dissipation to maintain performance within the specified junction temperature range.
Part Context
This part belongs to the BD68x series of power Darlington transistors, which includes complementary NPN variants like the BD679. These devices are designed for robust power handling in compact packages. The BD680ASTU specifically denotes the PNP polarity with the ASTU suffix indicating the DPAK surface-mount package type commonly used in consumer electronics and industrial control systems.
