NMB2227AH

Overview

The NMB2227AH is a dual general-purpose transistor comprising an NPN (TR1) and PNP (TR2) pair in a SOT457 (SC-74) TSOP6 surface-mount package. The NPN transistor supports a collector-emitter voltage of 40 V, while the PNP transistor handles -60 V. Both transistors provide a maximum continuous collector current of 600 mA. The device features a DC current gain ranging from 100 to 300 for both polarities at specified test conditions. Total power dissipation reaches 300 mW per device at 25 °C ambient temperature. Transition frequencies are rated at 300 MHz for the NPN and 200 MHz for the PNP transistor.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• Dual complementary configuration reduces component count
• Low profile SMD plastic package design

Applications

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

Procurement Notes

Verify the specific suffix 'H' against the official Nexperia ordering information table to confirm packaging details such as reel or cut tape specifications. Ensure the selected variant matches the required AEC-Q101 qualification status for target automotive applications. Confirm pinning alignment with the SC-74 footprint before finalizing procurement orders.

Selection Notes

Select this component for designs requiring matched NPN/PNP pairs in space-constrained layouts. Verify that the 40 V and -60 V voltage ratings accommodate the circuit's peak operating levels. Check thermal derating curves if operation exceeds 25 °C ambient temperature to ensure junction temperatures remain within the 150 °C limit during high-current switching events.

Part Context

This part belongs to Nexperia's low-power general-purpose bipolar transistor series designed for high-speed switching. It serves as a compact alternative to discrete single transistors, simplifying PCB layout for digital logic interfaces and analog signal processing tasks where complementary polarity control is necessary.
