Procurement Notes
Verify the specific suffix 'S' corresponds to the required hFE gain binning classification before procurement. Confirm that the '-TP' designation indicates tape and reel packaging containing 1000 pieces per reel. Ensure compliance with RoHS directives if halogen-free requirements are not met by the standard version. Purchase only from authorized distributors to guarantee authenticity and traceability.
Selection Notes
Select this component when a medium-power NPN transistor with a 50 V rating and 1 A current capacity is required in a compact SOT-89 footprint. Consider the hFE binning options (Q, R, or S) based on the necessary current gain for the specific circuit design. Evaluate the 500 mW power dissipation limit against thermal management constraints in the final assembly.
Part Context
This part belongs to the 2SD874A series of NPN silicon power transistors manufactured by Micro Commercial Components. It is designed as a complementary pair to the 2SB772 PNP transistor. The series utilizes planar technology to ensure robust performance in power amplifier and general switching applications within the specified voltage and current limits.
Replacement Considerations
The datasheet identifies the 2SB772 as the complementary PNP type. Verify pinout compatibility and electrical parameters against alternative SOT-89 NPN transistors with similar 50V/1A ratings before substitution.
FAQ
