NMB2227AX

Overview

The NMB2227AX is a dual general-purpose transistor comprising an NPN (TR1) and PNP (TR2) pair in a TSOP6 (SOT457) surface-mount package. The NPN transistor supports a collector-emitter voltage (VCEO) of 40 V, while the PNP variant handles -60 V. Both transistors provide a maximum continuous collector current of 600 mA. Key electrical characteristics include a DC current gain (hFE) ranging from 100 to 300 at 150 mA, with transition frequencies (fT) of 300 MHz for the NPN and 200 MHz for the PNP. Total power dissipation reaches 300 mW per device at 25 °C ambient temperature.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• Dual complementary configuration reduces component count
• High current capability suitable for switching applications

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. Ensure the procurement channel sources directly from Nexperia or authorized distributors to guarantee authenticity and traceability. Confirm that the delivered components match the SOT457 package outline and marking codes defined in the product data sheet.

Selection Notes

Select this component when a matched NPN/PNP pair is required in a compact footprint. Verify that the application voltage does not exceed the 40 V limit for the NPN section or -60 V for the PNP section. Consider the thermal resistance values if operating near the 600 mA current limit, as power dissipation constraints may require PCB copper area optimization for adequate heat sinking.

Part Context

This part belongs to Nexperia’s range of small-signal general-purpose transistors designed for space-constrained designs. It serves as a complementary pair solution, replacing two individual discrete transistors to simplify printed-circuit board layout and assembly processes. The AEC-Q101 qualification extends its utility into automotive electronic systems requiring robust performance.

Replacement Considerations

Direct functional substitutes within the same package family should be verified via the manufacturer's cross-reference tools. Ensure any replacement maintains the TSOP6 pinout compatibility and meets or exceeds the 600 mA current rating and specified voltage limits for both NPN and PNP sections.
