MMDT3906_R1_00001

Overview

The MMDT3906_R1_00001 is a dual PNP general-purpose switching transistor manufactured by Panjit International Inc. It features two electrically isolated transistors in an SOT-363 plastic package. The device supports a collector-emitter voltage (VCEO) of -40 V and a collector current (IC) of -200 mA. Maximum power dissipation is rated at 200 mW, with a junction temperature range from -55 °C to +150 °C. Electrical characteristics include a minimum DC current gain (hFE) of 30 at IC = -10 mA and VCE = -1.0 V. The component complies with EU RoHS 2.0 standards and utilizes lead-free plating.

Feature Summary

• Dual configuration containing two electrically isolated PNP transistors within a single ultra-small surface-mount package.
• Utilizes PNP epitaxial silicon planar design for reliable switching performance.
• Manufactured using green molding compound compliant with IEC 61249 standards.

Applications

• General purpose amplifier applications
• Portable electronic devices where board space is limited
• Hand-held computers and PDAs

Procurement Notes

Verify the specific ordering suffix against official Panjit documentation to confirm packaging details such as reel size or tape specifications. Ensure that the requested variant matches the required marking code and packing quantity. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance status prior to procurement.

Selection Notes

Select this component when a compact dual PNP solution is required for signal switching or amplification. The SOT-363 package offers significant space savings compared to discrete components. Verify that the -40 V voltage rating and -200 mA current limits align with the circuit requirements. Consider the thermal resistance and power dissipation capabilities for the intended operating environment.

Part Context

This component belongs to the MMDT3906 series of dual PNP transistors produced by Panjit. It serves as a surface-mount alternative to through-hole discrete transistors, consolidating two units into one footprint. The series is designed for portable electronics and general-purpose switching tasks requiring matched electrical characteristics between the internal transistors.

Replacement Considerations

Compatible substitutes include the MMDT3906HE3-TP from Micro Commercial Components and the MMDT3906-7-F from DiodesZetex. These alternatives share similar dual PNP configurations and voltage ratings but may differ in package dimensions or specific electrical tolerances. Verify pinout compatibility and thermal characteristics before substitution.
