PMP5501Y-QX

Overview

The PMP5501Y-QX is a dual PNP bipolar junction transistor (BJT) manufactured by Nexperia. It utilizes silicon planar technology and is housed in an SOT363-3 surface-mounted device plastic package. The component features matched transistors with a collector-emitter voltage (VCEO) of 45 V, a collector-base voltage (VCBO) of 50 V, and an emitter-base voltage (VEBO) of 5 V. It supports a maximum continuous DC collector current of 100 mA and has a power dissipation rating of 300 mW. The device exhibits a gain-bandwidth product (fT) of 175 MHz and a saturation voltage of 200 mV. It operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• Matched PNP/PNP configuration with high current gain matching ratio
• Internally isolated dual transistors in a compact SMD package

Applications

• Current mirror circuits
• Differential amplifier stages
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm if it denotes automotive qualification or a distinct packaging variant, as standard datasheets typically list 'Y'. Ensure the ordering part number matches the exact tape-and-reel specifications required for your assembly process.

Selection Notes

Select this component when a matched pair of PNP transistors is required for precision analog circuits. The SOT363-3 package offers space efficiency for dense PCB layouts. Consider the 45 V voltage rating and 100 mA current limit to ensure operation remains within safe operating area boundaries during design validation.

Part Context

This component belongs to the PMP5501 series of matched double transistors. It serves as the PNP/PNP complement to the NPN/NPN PMP4501Y. The series is designed for applications requiring tight parameter matching between two transistors within a single package.

Replacement Considerations

The PMP5501Y is the primary equivalent part number. Verify pinout compatibility with the SOT363-3 package before substitution.
