MMBTA05_R1_00001 is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Panjit International Inc.. Its product description is TRANS NPN 60V 0.5A SOT-23. Review the specifications below when checking this part for your BOM.
The MMBTA05_R1_00001 is an NPN high voltage transistor manufactured by Panjit International Inc. in a SOT-23 package. It features a collector-emitter voltage of 60V and a continuous collector current of 500mA. The device offers a DC current gain ranging from 100 to 100 at specified test conditions, with a maximum collector-emitter saturation voltage of 0.25V. Total device dissipation is rated at 225mW on FR-4 boards, operating within a temperature range of -55°C to +150°C.
Verify the specific ordering suffix matches the required packing quantity, as the datasheet lists both 3K and 12K reel options for this series. Confirm that the component marking corresponds to B05 to ensure correct part identification. Ensure procurement channels provide traceability via lot numbers as per manufacturer tracking requirements.
Select this component when a single NPN transistor with 60V breakdown is required in a compact surface mount footprint. Consider thermal derating above 25°C if operating near the 225mW limit. Compare against MMBTA06 or MMBTA55 variants if higher voltage ratings are needed for the specific circuit design.
This part belongs to the MMBTA05/06/55/56 series of high voltage transistors. It shares the same physical SOT-23 package and thermal characteristics as its PNP counterpart (MMBTA55) and higher voltage siblings (MMBTA06/MMBTA56). The series is designed for general electronic applications where space constraints and moderate power handling are primary considerations.
Direct substitutes include other NPN transistors in SOT-23 packages with VCEO >= 60V and IC >= 500mA. Verify pinout compatibility and thermal resistance values before substitution.
The component marking code for the MMBTA05 is B05.
No, the datasheet explicitly states these products are not authorized for medical instruments or life-saving equipment.
