MMDT5111W-AQ

Overview

The MMDT5111W-AQ is a surface-mount digital PNP transistor manufactured by Diotec Semiconductor, housed in an SOT-323 package. It integrates bias resistors to simplify circuit design and reduce component count. The device features a collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW at 25°C ambient temperature. It operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a DC current gain (hFE) of 35 at -IC = -10 mA and -VCE = -5 V, a transition frequency of 250 MHz, and typical base-emitter and collector-base cutoff currents of 500 nA and 100 nA respectively.

Feature Summary

• Integrates bias resistor combinations for cost and space savings
• Compliant with AEC-Q101 automotive standards due to the -AQ suffix
• RoHS compliant without exemptions and REACH compliant

Applications

• Digital controls
• Switching applications
• Signal processing

Procurement Notes

Verify the specific ordering suffix to confirm compliance status. The -AQ suffix indicates AEC-Q101 qualification, while other suffixes may denote different grades. Confirm mechanical data such as tape and reel specifications and moisture sensitivity level before procurement. Ensure the supplier provides official documentation matching the exact part number variant.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required for space-constrained designs. The -AQ suffix is necessary for automotive applications requiring AEC-Q101 qualification. Consider the -50 V voltage rating and -100 mA current capability against load requirements. Verify thermal management needs given the 200 mW power dissipation limit in the SOT-323 package.

Part Context

This part belongs to the MMDT5110W through MMDT511NW series of SMD digital PNP transistors from Diotec Semiconductor. The series offers various resistor configurations to suit different logic interface needs. The MMDT5111W variant specifically pairs a 47 kOhm input resistor with a 10 kOhm output resistor. The -AQ designation signifies automotive qualification within this product family.

Replacement Considerations

Check for equivalent parts in the MMDT511x series with matching resistor values if pin compatibility is required. Verify that any substitute meets the same AEC-Q101 qualification if the -AQ suffix is critical. Ensure the replacement supports the -50 V and -100 mA ratings.
