MJE13003D-BP

Single Bipolar Transistors Overview

The MJE13003D-BP is an NPN silicon plastic-encapsulated transistor manufactured by Micro Commercial Components (MCC). It is designed for high-voltage, high-speed power switching applications in inductive circuits. The device features a collector-emitter sustaining voltage of 300V and a maximum collector current of 1.5A. Key electrical parameters include a collector-emitter saturation voltage of 1.0V maximum at IC=1.0A and IB=0.25A, with a storage time of 0.7μs maximum at IC=1.0A.

Single Bipolar Transistors Procurement Notes

Verify the specific package type (e.g., TO-126, TO-92) associated with the -BP suffix against the official MCC datasheet, as packaging can vary by manufacturer lot. Confirm RoHS compliance status directly from the component marking or latest documentation. Ensure thermal management requirements are met for the intended operating temperature range. Cross-reference pin assignments with the specific datasheet revision to avoid circuit errors during assembly.

Single Bipolar Transistors Selection Notes

Select this component when a 300V NPN transistor is required for high-speed switching applications. Compare saturation voltage and switching times against circuit requirements to ensure adequate performance margins. Consider the thermal dissipation capabilities of the chosen package style relative to the expected load current. Verify that the base drive current can achieve the specified saturation levels under worst-case temperature conditions.

Single Bipolar Transistors Part Context

The MJE13003 series belongs to a family of NPN silicon power transistors widely used in consumer electronics and industrial power supplies. Variants like the MJE13003L and MJE13003G often denote different package styles or minor parameter variations within the same functional class. The -BP suffix typically indicates lead-free and halogen-free compliance in MCC's product line, aligning with environmental standards.

Single Bipolar Transistors Replacement Considerations

Substitutes must match the 300V VCEO rating and 1.5A IC capability. Compatible alternatives include the ST13003A (note: higher voltage rating) or KSE13003. Verify pinout compatibility and thermal resistance before replacement. Ensure the substitute device meets the same switching speed requirements for the specific application.
