PQMB11Z

Overview

The PQMB11 is a PNP/PNP Resistor-Equipped Transistor (RET) housed in a leadless DFN1010B-6 (SOT1216) surface-mounted package. It integrates two PNP transistors with built-in bias resistors, specifically R1 = 10 kΩ and R2 = 10 kΩ. The device supports a collector-emitter voltage of -50 V and an output current capability of 100 mA per transistor. Key electrical characteristics include a DC current gain (hFE) of 30 at -5 mA and a transition frequency (fT) of 180 MHz. The component is AEC-Q101 qualified for automotive applications and features a low profile height of 0.37 mm.

Feature Summary

• Integrates dual PNP transistors with fixed internal bias resistors to simplify circuit topology
• AEC-Q101 qualified for reliability in automotive environments
• Ultra-thin leadless DFN1010B-6 package minimizes board space and assembly costs

Applications

• Low current peripheral driver circuits
• Control of IC inputs
• Digital applications replacing general-purpose transistors
• Mobile electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the DFN1010B-6 footprint matches your PCB design guidelines. Ensure compliance with RoHS directives and check for any regional export control restrictions applicable to discrete semiconductors before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a leadless ultra-small outline package. The integrated bias resistors eliminate external components, reducing bill of materials count. Verify that the required collector-emitter voltage rating of -50 V and current capacity of 100 mA align with your circuit demands. Consider the thermal resistance characteristics if operating near ambient temperature limits.

Part Context

The PQMB11 belongs to Nexperia's family of resistor-equipped transistors designed for digital switching and signal control. It serves as the PNP/PNP variant within the series, complemented by NPN/NPN (PQMH11) and NPN/PNP (PQMD3) options. This integration strategy targets high-volume consumer and automotive electronics where miniaturization and simplified assembly are critical design drivers.

Replacement Considerations

Direct functional substitutes may include other PNP/PNP RETs from various manufacturers offering similar -50V ratings and 100mA current capabilities. Verify pinout compatibility and bias resistor values (R1/R2) to ensure logical equivalence. Package dimensions must match the DFN1010B-6 form factor for direct replacement without PCB redesign.
