MMDT5213W-AQ

Overview

The MMDT5213W-AQ is an NPN Silicon Epitaxial Planar Digital Transistor manufactured by Diotec Semiconductor. It integrates bias resistors within a compact SOT-323 surface-mount package, designed for cost and space savings in digital control and switching applications. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IO) of 100 mA. Power dissipation is rated at 200 mW with a junction temperature range of -55°C to +150°C. Electrical characteristics include a typical DC current gain (GI) of 80 at VO = 5 V and IO = 10 mA, and a transition frequency (fT) of 250 MHz. The internal resistor configuration consists of R1 = 47 kΩ and R2 = 10 kΩ.

Feature Summary

• Integrated bias resistors reduce component count and PCB footprint
• AEC-Q101 qualified for automotive reliability standards
• RoHS compliant and free from conflict minerals

Applications

• Digital controls
• Switching circuits
• Signal processing

Procurement Notes

Verify the specific suffix '-AQ' confirms AEC-Q101 qualification status directly from the manufacturer's official documentation before procurement. Ensure the ordering part number matches the required resistor values and package type. Confirm compliance requirements such as RoHS and REACH against project specifications. Request the latest datasheet version to validate any potential design changes or updates prior to finalizing supply agreements.

Selection Notes

Select this component when an NPN digital transistor with integrated biasing is required for low-power switching tasks. The 47 kΩ base resistor and 10 kΩ emitter resistor suit specific logic interface needs. Verify that the 50 V voltage rating and 100 mA current capacity meet circuit demands. Consider the SOT-323 package constraints for thermal management and spatial limitations in dense layouts.

Part Context

This part belongs to the MMDT521xW series of SMD digital NPN transistors. The series offers various resistor combinations to accommodate different drive requirements. The MMDT5213W variant specifically pairs a 47 kΩ input resistor with a 10 kΩ emitter resistor. The '-AQ' suffix denotes automotive-grade qualification under AEC-Q101 standards, distinguishing it from standard commercial grades.

Replacement Considerations

Check for other MMDT521xW variants with identical 47 kΩ / 10 kΩ resistor ratios if stock is unavailable. Verify that alternative parts match the SOT-323 package dimensions and electrical ratings. Ensure any substitute also meets AEC-Q101 requirements if automotive application is intended.
