UMB4NTN

Overview

The UMB4NTN is a dual PNP digital transistor from ROHM Semiconductor, housed in a compact SOT-363 (UMT6) surface-mount package. It integrates two PNP transistors with built-in base resistors to simplify circuit design. Key electrical specifications include a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device features a typical input resistance of 1kΩ for each transistor channel. It supports a maximum operating temperature of +150°C and has a power dissipation rating of 150mW.

Feature Summary

• Integrates two PNP transistors with internal biasing resistors to reduce external component count.
• Designed for high-frequency applications with a transition frequency up to 250MHz.
• Utilizes a small UMT6 (SOT-363) surface-mount package for space-constrained designs.

Applications

• Differential amplifier circuits for pre-amplification stages
• High-frequency crystal oscillators
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix 'TN' to confirm the tape-and-reel packaging configuration containing 3000 units per reel. Ensure compatibility with RoHS standards if required by the target application. Confirm that the component status is active for new designs, as availability may vary by region or distributor.

Selection Notes

Select this component when a dual PNP configuration with integrated base resistors is required. The 1kΩ input resistance is suitable for direct interfacing with standard logic outputs. Consider the -50V voltage rating and -100mA current capability against load requirements. The UMT6 package is ideal for dense PCB layouts where space is limited.

Part Context

The UMB4NTN belongs to the UMB4 series of dual digital transistors manufactured by ROHM Semiconductor. This series is characterized by its small footprint and integrated resistor network, which simplifies switching and amplification tasks. It serves as a compact alternative to discrete transistor pairs, offering consistent performance in consumer electronics and industrial control systems.

Replacement Considerations
