MMDTA141DW

Overview

The MMDTA141DW is a surface-mount digital PNP transistor manufactured by Diotec Semiconductor. It integrates two transistors within a single SOT-363 package, featuring built-in bias resistor combinations for cost and space efficiency. The device supports a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA per transistor. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at 5 mA, an input resistance (R1) typically rated at 10 kΩ with a ratio to the second resistor (R2) of 1. Thermal performance allows operation up to a junction temperature of 150°C, with a total power dissipation of 200 mW.

Feature Summary

• Dual PNP transistors integrated into a compact SOT-363 package

• High switching speed with a transition frequency of 200 MHz
• Compliant with RoHS directives and REACH regulations

Applications

• Digital control circuits
• General-purpose switching applications
• Signal processing modules

Procurement Notes

Verify that the specific part number matches the required configuration before ordering. Confirm compliance requirements such as AEC-Q101 if automotive standards are necessary, as these may require distinct suffixes like -Q or -AQ. Ensure the procurement documentation aligns with the manufacturer's standard terms and conditions regarding liability and product changes.

Selection Notes

Select this component when designing circuits requiring dual PNP logic functions in a minimal footprint. Verify that the 10 kΩ typical input resistance suits the driving interface. Ensure the design accommodates the 200 mW power dissipation limit and operates within the specified -55°C to +150°C temperature range for commercial or industrial environments.

Part Context

This component belongs to the MMDTA series of SMD digital PNP transistors produced by Diotec Semiconductor. It is designed for high-density PCB layouts where multiple discrete components would otherwise be required. The integration of bias resistors simplifies the design process for logic interfacing and switching tasks.

Replacement Considerations

Consult official distributor databases for cross-references. Verify pinout compatibility and electrical ratings against potential substitutes. Ensure any replacement maintains the SOT-363 form factor and meets the -50 V and -100 mA specifications.
