MMDT3906TB6_R1_00001

Overview

The MMDT3906TB6_R1_00001 is a dual PNP general-purpose switching transistor manufactured by Panjit International Inc. It features two electrically isolated PNP transistors encapsulated in an SOT-563 plastic case. The device operates with a collector-emitter voltage of -40V and a continuous collector current of -200mA. Total power dissipation is rated at 200mW, with a junction temperature range from -55°C to +150°C. Electrical characteristics include a DC current gain (hFE) ranging from 30 to 300 at specific test conditions, a collector-emitter saturation voltage of -0.4V maximum, and a base-emitter saturation voltage of -0.58V maximum.

Feature Summary

• Contains two electrically isolated PNP transistors within a single ultra-small package for board space efficiency.
• Utilizes a planar epitaxial silicon design compatible with standard surface mount assembly processes.
• Manufactured using lead-free plating and green molding compounds compliant with RoHS 2.0 and IEC 61249 standards.

Applications

• General purpose amplifier applications
• Hand-held computers and PDAs
• Portable electronic devices requiring compact switching solutions

Procurement Notes

Verify the ordering suffix against official documentation to confirm packaging specifications. The suffix indicates tape and reel configuration on a 7-inch plastic reel. Confirm compliance requirements such as RoHS 2.0 and halogen-free status directly with the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component when dual isolated PNP switching is required in a minimal footprint. Ensure the application voltage does not exceed the -40V collector-emitter rating. Verify that the thermal management strategy accommodates the 200mW total power dissipation limit under expected operating conditions.

Part Context

This part belongs to the MMDT3906 series of dual PNP transistors. It serves as a compact alternative to discrete single transistors, reducing assembly complexity. The SOT-563 package allows for high-density PCB layouts compared to larger through-hole or standard surface-mount packages.

Replacement Considerations

Direct replacements must match the SOT-563 package and electrical ratings. Verify pinout compatibility and isolation requirements. Cross-reference with other manufacturers' dual PNP SOT-563 parts ensuring identical VCEO and IC specifications.
