MMBT3906

Single Bipolar Transistors Overview

The Good-Ark MMBT3906 is a PNP silicon epitaxial planar transistor designed for surface mounting in the SOT-23 plastic package. It serves as the complementary device to the MMBT3904 NPN transistor. The component supports a maximum collector current of -0.2 A and withstands collector-emitter voltages up to -40 V. Key electrical characteristics include a DC current gain (hFE) ranging from 30 to 300 at specific test conditions, a transition frequency of 300 MHz, and a collector power dissipation of 0.2 W. It operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify that the ordered components match the Good-Ark Semiconductor datasheet specifications exactly. Confirm RoHS compliance status and ensure the SOT-23 package dimensions align with your PCB footprint requirements. Check for the correct marking code '2A' on the device body to authenticate the manufacturer and part number before integration into production.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage, general-purpose PNP switch or amplifier is required in a compact form factor. Ensure the design accommodates the 0.2 W power dissipation limit and verify that the -40 V voltage ratings meet the circuit's peak operating conditions. Consider the complementary MMBT3904 if an NPN counterpart is needed for push-pull configurations.

Single Bipolar Transistors Part Context

The MMBT3906 belongs to the family of small-signal bipolar junction transistors widely used in consumer electronics and industrial control systems. Manufactured by Good-Ark Semiconductor, it utilizes epitaxial planar technology to ensure consistent performance. The SOT-23 package allows for automated assembly, making it suitable for high-volume manufacturing environments requiring reliable signal processing or switching capabilities.

Single Bipolar Transistors Replacement Considerations

The MMBT3904 is the documented complementary NPN type. Other generic PNP transistors with matching SOT-23 packages and similar -40V/-200mA ratings may serve as substitutes, provided their hFE and saturation voltage parameters are verified against the original design requirements.
