PUMD3-QX

Overview

The PUMD3-QX is an AEC-Q101 qualified digital transistor array manufactured by Nexperia USA Inc. It integrates one NPN and one PNP pre-biased transistor within a compact SOT-363 (TSSOP-6) surface-mount package. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA, with a total power dissipation rating of 200mW. Each transistor includes an integrated base resistor of 10 kOhms, facilitating direct logic interface without external biasing components. The unit exhibits a minimum DC current gain (hFE) of 30 at 5mA and 5V, ensuring reliable switching performance in automotive and industrial environments.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Integrated dual NPN/PNP configuration with built-in base resistors
• Compact SOT-363 surface-mount packaging for space-constrained designs

Applications

• Automotive digital signal switching circuits
• Interface between microcontrollers and peripheral devices
• Logic level translation in embedded systems

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm it denotes the tape-and-reel packaging format and AEC-Q101 qualification status. Ensure that the ordering code matches the exact electrical specifications required for the target application, as suffix variations may indicate differences in packaging or qualification levels.

Selection Notes

Select this component when an automotive-grade, dual-channel digital transistor solution is required. The integrated 10 kOhm base resistors simplify circuit design by eliminating external biasing components. Verify that the 50V voltage rating and 100mA current capacity align with the load requirements of the specific switching application.

Part Context

The PUMD3 series represents Nexperia's line of pre-biased digital transistors designed to replace discrete resistor-transistor networks. The '-QX' variant specifically targets automotive applications through AEC-Q101 certification, offering enhanced reliability compared to standard commercial grade counterparts while maintaining the same functional pinout and electrical characteristics.
