PUMD48-QH

Overview

The PUMD48-Q is an NPN/PNP Resistor-Equipped Double Transistor (RET) housed in a SOT363-3 (SC-88) plastic surface-mounted package. It integrates two transistors with built-in bias resistors to reduce component count and simplify circuit design. The device features a collector-emitter voltage (VCEO) of 50 V and an output current capability of 100 mA per transistor. TR1 (NPN) includes a typical input resistor R1 of 47 kΩ, while TR2 (PNP) has a typical R1 of 2.2 kΩ. Both resistors share a common R2 value of 47 kΩ. Qualified under AEC-Q101, it supports automotive applications with a total power dissipation of 300 mW and operates within a junction temperature range up to 150 °C.

• Replacement for general-purpose transistors in digital applications

Procurement Notes

Verify the specific ordering code against the manufacturer's official distributor list to ensure authenticity. Confirm that the SOT363-3 package variant matches the design footprint requirements. Check the latest datasheet revision history for any updates to pinning or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require combining dual transistors with fixed bias networks. Ensure the 50 V rating accommodates peak voltages and the 100 mA current limit suits the load. Verify that the integrated resistor values (47 kΩ and 2.2 kΩ) align with the required base drive currents for the target logic levels.

Part Context

This part belongs to Nexperia's family of Resistor-Equipped Transistors (RETs), designed to replace multiple discrete components. The PUMD48-Q specifically pairs an NPN with a high-input-resistance PNP, offering a complementary solution for interface circuits where different input impedance requirements exist for each channel.

Replacement Considerations

Direct replacements must match the SOT363-3 package and internal resistor ratios. Verify compatibility with existing footprints if substituting from older SOT363 revisions. Ensure the replacement maintains AEC-Q101 qualification if used in automotive systems.
