PUMD4,115

Overview

The PUMD4,115 is a dual pre-biased NPN/PNP transistor array manufactured by Nexperia USA Inc. It integrates two transistors with built-in bias resistors in a compact surface-mount package. The device features a maximum collector-emitter voltage (Vceo) of 50V and a continuous collector current (Ic) of 100mA per transistor. The internal base resistor (R1) is specified at 10 kΩ, while the emitter resistor (R2) is left open. Key electrical parameters include a DC current gain (hFE) minimum of 30 at Ic=5mA, Vce=5V, and a saturation voltage (Vce(sat)) maximum of 150mV at Ib=500µA, Ic=10mA. The component supports an operating temperature range from -65°C to +150°C and is housed in a 6-TSSOP (SC-88/SOT-363) package.

Feature Summary

• Integrated bias resistors simplify circuit design and reduce component count
• Dual configuration combining one NPN and one PNP transistor
• Automotive grade qualification ensuring reliability in harsh environments

Applications

• Low current peripheral drivers
• Replacement of general purpose transistors in digital applications
• Control of IC inputs

Procurement Notes

Verify the specific ordering suffix and packaging format required for production integration. Confirm that the 6-TSSOP footprint matches the PCB layout constraints. Ensure compliance with RoHS3 directives and REACH regulations as stated in the official documentation. Check for any recent Product Change Notifications regarding assembly or labeling updates before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require dual switching functions with integrated biasing. The 50V rating and 100mA current capacity suit low-power digital logic interfacing. Consider the 10kΩ base resistance value for appropriate drive current requirements. Verify thermal management capabilities within the 300mW power dissipation limit for the intended application environment.
