NMB2227AZ

Overview

The NMB2227AZ is a dual general-purpose transistor comprising an NPN (TR1) and PNP (TR2) pair in a SOT457 (SC-74) TSOP6 package. The NPN collector-emitter voltage (VCEO) is 40 V, while the PNP VCEO is -60 V. Both transistors support a maximum continuous collector current of 600 mA. Peak collector current reaches 800 mA for single pulses. Total power dissipation is rated at 300 mW per device at 25 °C ambient temperature. The junction temperature range extends from -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive applications
• Complementary NPN/PNP configuration reduces component count
• High current capability suitable for switching and amplification

Applications

• General-purpose switching and amplification
• Complementary driver circuits
• Half-bridge and full-bridge drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Confirm that the requested variant matches the exact pinning and marking codes defined in the latest product data sheet version before finalizing procurement orders.

Selection Notes

Select this component when a complementary NPN/PNP pair is required in a compact surface-mount footprint. Ensure the design accounts for the 300 mW total power dissipation limit and the distinct voltage ratings between the NPN (40 V) and PNP (-60 V) sections. Verify thermal management requirements based on the specified junction-to-ambient resistance values.

Part Context

This part belongs to Nexperia's line of small SMD plastic package transistors designed for space-constrained PCB layouts. It serves as a general-purpose solution for digital and analog switching tasks where complementary transistor pairs are preferred over discrete individual components.

Replacement Considerations

Check for direct functional equivalents with identical pinning and electrical characteristics. Verify package compatibility and thermal performance if substituting with parts from other manufacturers.
