Overview
The MMDTA141DW-AQ 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 to reduce component count and board space. The device operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA per transistor. Power dissipation is rated at 200 mW, with a junction temperature range spanning from -55°C to +150°C. The typical input resistance is 10 kΩ, and the DC current gain (hFE) has a minimum value of 30 at 5 mA. This component is designed for commercial and industrial applications.

Procurement Notes
Verify that the specific ordering suffix matches the required automotive qualification level. Confirm compliance with RoHS, REACH, and Conflict Minerals regulations as stated in the official datasheet. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor components.
Selection Notes
Select this component when a compact solution for dual PNP switching is required. The integrated bias resistors simplify circuit design by reducing external component requirements. Verify that the -50 V voltage rating and -100 mA current capacity align with the target application's electrical demands before finalizing the design.
Part Context
This part belongs to the MMDTA series of SMD digital transistors produced by Diotec Semiconductor. The series offers various configurations and resistance values tailored for different logic interface needs. The MMDTA141DW variant specifically utilizes the SOT-363 footprint, which is widely adopted in modern consumer electronics and industrial equipment for its small form factor.
Replacement Considerations
Consult official cross-reference lists or manufacturer documentation for verified equivalent parts. Ensure any substitute maintains identical pinout configuration, voltage ratings, and thermal characteristics to prevent circuit malfunction.
