MMDT2227

Overview

The MMDT2227 is a surface-mount general-purpose complementary NPN and PNP bipolar junction transistor array manufactured by Diotec Semiconductor. It integrates two transistors in a single SOT-363 package, providing a compact solution for signal processing, switching, and amplification applications. The device features a maximum collector current of 600 mA per transistor and a total power dissipation of 200 mW. Voltage ratings include VCEO values of 40 V for the NPN and -60 V for the PNP transistor. The unit operates within a junction temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• Integrates one NPN and one PNP complementary transistor into a single SOT-363 package
• Designed for commercial and industrial grade signal processing, switching, and amplification tasks
• Compliant with RoHS directives without exemptions

Applications

• Signal processing circuits
• Electronic switching applications
• Amplification stages

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard version is intended for commercial and industrial use. Versions with the -Q suffix are AEC-Q101 compliant, while the -AQ suffix indicates parts undergoing automotive qualification. Confirm that the required reliability grade matches the application needs before procurement.

Selection Notes

Select this component for designs requiring dual complementary transistors in a minimal footprint. Ensure the circuit voltage does not exceed the 40 V limit for the NPN or -60 V for the PNP transistor. Verify thermal management requirements against the 200 mW power dissipation rating and the specified thermal resistance of 420 K/W under standard mounting conditions.
