PUMD2/DG/B4F

Overview

The PUMD2/DG/B4F is a dual resistor-equipped transistor (RET) array manufactured by Nexperia USA Inc. It integrates one NPN and one PNP bipolar junction transistor within a single surface-mount package. The device features an integrated base resistor of 22 kΩ for each transistor, facilitating simplified biasing in digital switching applications. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a total power dissipation of 300mW. The component is housed in a compact 6-TSSOP (SC-88/SOT-363) package, designed for efficient PCB layout in space-constrained electronic circuits.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in base resistors to reduce external component count
• Utilizes a low-profile 6-TSSOP surface-mount package for high-density board assembly
• Provides symmetrical switching characteristics through matched NPN/PNP configurations

Applications

• Digital logic level shifting and interface circuits
• General-purpose switching applications requiring complementary outputs
• Driver stages for small-signal loads in consumer electronics

Procurement Notes

Verify the specific suffix /DG/B4F against official Nexperia documentation to confirm tape-and-reel packaging quantities and marking codes. Ensure compatibility with standard 6-TSSOP footprints during procurement planning. Cross-reference the part number with authorized distributors to confirm current availability status and lead times, as supply chain conditions may vary.

Selection Notes

Select this component when a complementary NPN/PNP pair with fixed base resistance is required in a minimal footprint. The 22kΩ internal resistors simplify drive circuit design compared to discrete transistors. Verify that the 50V voltage rating and 100mA current capacity meet the specific load requirements of the target application before finalizing the design.

Part Context

This part belongs to the PUMD2 family of dual resistor-equipped transistors from Nexperia. It serves as the complementary counterpart to the PQMH2 series, offering both NPN and PNP options in a single package. The PUMD2 variant specifically combines one NPN and one PNP transistor, providing flexibility for push-pull or differential signaling applications where space savings are critical.

Replacement Considerations

Direct substitutes include the PUMD2,115 and PUMD2-QX variants, which share identical electrical characteristics and pinout configurations. These alternatives offer the same NPN/PNP dual configuration with 22kΩ base resistors in the 6-TSSOP package. Verify package dimensions and thermal performance when swapping between these specific Nexperia part numbers.
