DTA115EU3HZGT106

Overview

The DTA115EU3HZGT106 is a PNP digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOT-323 (UMT3) package. It integrates biasing resistors with R1 and R2 both at 100 kOhms, eliminating the need for external input components. The device supports a collector current of 100 mA and a supply voltage of -50 V, with a power dissipation rating of 200 mW. It features a minimum DC current gain (hFE) of 82 at 5 mA and 5 V, operating up to a maximum frequency of 250 MHz. The component is qualified under AEC-Q101 standards for automotive reliability.

Feature Summary

• Integrates dual biasing resistors (R1=R2=100kΩ) to simplify circuit design by removing the need for external input resistors.
• AEC-Q101 qualified for high reliability in automotive environments.
• Compact SOT-323 surface-mount package suitable for space-constrained designs.

Applications

• Inverter circuits
• Interface drivers
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'HZGT106' against official ROHM documentation to confirm packaging details and compliance status. Ensure compatibility with existing PCB footprints for the SOT-323 package. Cross-reference the AEC-Q101 qualification requirements if used in automotive-grade assemblies. Confirm lead times and production status directly with authorized distributors as availability may vary.

Selection Notes

Select this component when a PNP digital transistor with equal biasing resistors (100 kOhms) is required. It serves as a direct replacement for other DTA115 series variants within the same package family. Consider the -50 V collector-emitter voltage and 100 mA current limits during circuit design. Verify thermal management capabilities given the 200 mW power dissipation rating in the small outline package.

Part Context

This part belongs to the ROHM DTA115 series of pre-biased transistors. It is the PNP counterpart to the NPN DTC115 series. The 'EU3' designation indicates the SOT-323 package type. The 'HZG' suffix typically denotes automotive grade and specific tape-and-reel packaging configurations. It is part of ROHM's portfolio of compact, high-reliability discrete semiconductors.

Replacement Considerations

Compatible replacements include other DTA115 series parts in the SOT-323 package, such as DTA115EU3 or DTA115EMHZG, provided pinouts and electrical characteristics match. Verify that substitute parts meet the same AEC-Q101 automotive qualification standards if applicable to the application.
