UMF32NTR

Overview

The UMF32NTR is a dual digital transistor manufactured by Rohm Semiconductor, housed in a surface-mount UMT6 package (equivalent to SOT-363). It integrates a PNP pre-biased transistor and an N-channel transistor within a single compact component. The device supports a maximum voltage rating of 50V for the PNP section and 30V for the N-channel section. Both transistors are rated for a continuous collector current of 100mA. This configuration allows for simplified circuit design by combining two distinct transistor types in one footprint.

Feature Summary

• Integrates both PNP pre-biased and N-channel transistors into a single dual configuration
• Utilizes a compact UMT6 surface-mount package for space-efficient PCB layouts
• Designed for general-purpose switching applications requiring mixed polarity control

Applications

• General-purpose digital switching circuits
• Interface driver stages requiring mixed PNP/NPN logic levels
• Signal conditioning modules in consumer electronics

Procurement Notes

Verify the NRND status with the manufacturer before finalizing designs, as this indicates the component may be phased out. Confirm that the UMT6 package dimensions match your board layout constraints. Ensure supply chain availability aligns with production timelines, as end-of-life products may have limited long-term sourcing options.

Selection Notes

Select this component when a design requires both PNP and N-channel switching capabilities in a minimal footprint. The integrated nature reduces external resistor requirements compared to discrete solutions. Verify that the 50V/30V voltage ratings and 100mA current limits meet the specific load requirements of the target application without exceeding absolute maximum ratings.

Part Context

This part belongs to Rohm's UMF series of complex digital transistors. These components are designed to replace multiple discrete transistors and biasing resistors, simplifying assembly and reducing board space. The UMF32NTR specifically addresses applications needing complementary transistor pairs in a standardized small outline package format.

Replacement Considerations

Check for direct pin-compatible alternatives within the same UMT6 package family. Verify electrical equivalence for both the PNP and N-channel sections independently. Consider newer generation devices if the NRND status poses supply risks.
