MMBTA56WT1G

Single Bipolar Transistors Overview

The MMBTA56WT1G is a single PNP silicon bipolar junction transistor manufactured by onsemi. It is housed in an SC-70-3 surface-mount package. The device supports a maximum collector current of 500 mA and withstands collector-emitter and collector-base voltages of 80 V each, with an emitter-base voltage rating of 4 V. Power dissipation reaches 460 mW at 25°C ambient temperature. The transition frequency is specified at 50 MHz, and the unit operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• Single PNP configuration designed for general-purpose switching and amplification applications.
• SC-70-3 surface-mount packaging enables compact circuit board layout and automated assembly.
• High thermal stability allows operation up to 150°C junction temperature.

Single Bipolar Transistors Applications

• Low-power amplifier stages
• Driver interfaces for logic-level control

Single Bipolar Transistors Procurement Notes

Verify the specific suffix WT1G against the official datasheet to confirm the SC-70-3 package type and reel quantity specifications. Ensure that the ordering documentation matches the manufacturer's part number exactly to avoid receiving variants with different electrical characteristics or packaging formats. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 80 V breakdown voltage and 500 mA continuous current capability is required in a minimal footprint. The SC-70-3 package is suitable for space-constrained designs where SMT assembly is preferred. Consider the 460 mW power dissipation limit and thermal resistance values during PCB layout planning to ensure reliable operation under load conditions without exceeding maximum junction temperatures.

Single Bipolar Transistors Part Context

This component belongs to the MMBTA56W series of small-signal transistors from onsemi. It serves as a complementary counterpart to NPN devices within the same family, such as the SMMBTA06WT1G. The series is engineered for high-volume consumer electronics and industrial applications requiring reliable switching performance in miniature packages.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other PNP transistors in the SC-70-3 package with matching 80 V and 500 mA ratings. Verify pinout compatibility and thermal characteristics before substitution. Generic equivalents may differ in gain bandwidth or saturation voltage.
