BD680AS

Overview

The BD680AS is a plastic, medium-power silicon PNP Darlington transistor manufactured by onsemi. It features a monolithic construction with high DC current gain, specified as a minimum of 750 at collector currents of 1.5 A and 2.0 A. The device is part of a complementary series designed for general-purpose amplifier applications. It is available in Pb-free packages and serves as an equivalent to specific legacy components such as the MJE 703.

Procurement Notes

Verify the specific suffix 'AS' against the official onsemi datasheet to confirm package type and tape-and-reel specifications. Ensure compliance requirements match project needs. Confirm availability status as Active or Obsolete through authorized distributors. Request Material Composition Declaration (MCD) if RoHS or REACH compliance documentation is required for procurement records.

Selection Notes

Select this component for applications requiring high current gain in PNP configurations. Consider its equivalence to MJE 703 when designing with legacy schematics. Evaluate thermal management requirements for medium-power operation. Verify that the complementary NPN counterpart meets system symmetry requirements for push-pull or differential stages.

Part Context

The BD680AS belongs to the family of plastic medium-power silicon PNP Darlingtons from onsemi. This series includes complementary parts like the BD679A. The devices utilize planar base island technology with monolithic Darlington configuration. They are engineered for robust performance in linear and switching amplifier roles within consumer and industrial electronics.

Replacement Considerations

The BD680AS is documented as equivalent to the MJE 703. Designers replacing this part should verify pinout compatibility and thermal characteristics against the MJE 703 specification sheet to ensure functional interchangeability in existing circuit layouts.
