PMBT2227AYS-QH

Overview

The PMBT2227AYS-Q is a dual switching transistor containing one NPN and one PNP bipolar junction transistor within a TSSOP6 (SOT363-3) surface-mount package. It supports a maximum collector current of 600 mA per device, with peak currents reaching 800 mA for single pulses up to 1 ms. The NPN transistor provides a collector-emitter voltage rating of 40 V, while the PNP transistor handles -60 V. DC current gain ranges from 100 to 300 at 150 mA. Transition frequencies are specified at 300 MHz for the NPN section and 200 MHz for the PNP section. Total power dissipation reaches 550 mW on standard PCB footprints.

Feature Summary

Procurement Notes

Verify the specific suffix 'QH' against official Nexperia documentation before procurement, as the provided datasheet references 'AYS-Q'. Confirm that the ordering code matches the exact package version and manufacturing site requirements. Ensure design parameters align strictly with the absolute maximum ratings defined in the product data sheet to prevent device damage.

Selection Notes

Select this component when space-constrained designs require both NPN and PNP switching capabilities in a single footprint. Evaluate thermal resistance values based on the intended PCB copper area and mounting pad size. Verify that operating voltages remain within the distinct limits for each transistor polarity to ensure reliable performance across the specified temperature range.

Part Context

This device belongs to the PMBT2227 series of dual switching transistors manufactured by Nexperia. It serves as a compact alternative to discrete single-transistor solutions, reducing board space and assembly complexity.
