2SB1386-R-TP is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists MCC (Micro Commercial Components). Its product description is TRANS PNP 20V 5A SOT-89. Review the specifications below when checking this part for your BOM.
The MCC 2SB1386-R-TP is a PNP silicon epitaxial transistor housed in an SOT-89 package. It features a collector-emitter voltage of -20 V, a collector-base voltage of -30 V, and an emitter-base voltage of -6 V. The device supports a continuous collector current of -500 mA and a pulsed current of -10 A, with a power dissipation rating of 500 mW at 25°C. The 'R' suffix indicates a DC current gain (hFE) range of 180 to 390. It operates within a junction temperature range of -55°C to +150°C.
Verify the component marking code on the physical device matches 'BHR', which corresponds to the R-rank hFE classification. Confirm the package type is SOT-89 and that the part number includes the '-TP' suffix for tape and reel packaging containing 1000 pieces per reel. Ensure sourcing from authorized distributors to guarantee authenticity and traceability.
Select this component when a PNP transistor with a -20 V collector-emitter voltage and -500 mA continuous current capability is required. The R-rank provides a high minimum gain of 180, suitable for applications demanding reliable amplification without excessive base drive current. Consider the thermal resistance of 250°C/W when designing heat dissipation strategies for ambient temperatures exceeding 25°C.
This device belongs to the 2SB1386 series manufactured by Micro Commercial Components. The series includes P-rank (82-180 gain) and Q-rank (120-270 gain) variants alongside the R-rank. All variants share identical electrical ratings and pin configurations but differ strictly in their DC current gain binning specifications.
Direct substitutes include other PNP transistors with similar -20V VCEO, -500mA IC, and SOT-89 packaging. Verify that replacement parts meet or exceed the required hFE range of 180-390 and maintain comparable saturation voltages at -4A/-0.1A conditions if used in high-current switching roles.
The 'R' marking, appearing as 'BHR' on the device body, designates the specific DC current gain (hFE) rank, which ranges from 180 to 390.
The maximum pulsed collector current (ICP) is specified as -10 A.
Yes, the device is lead-free finish and RoHS compliant, as indicated by the product description and manufacturer notes.
