DTA114GUAT106

Overview

The DTA114GUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in a UMT3 (SOT-323) surface-mount package. It integrates bias resistors with typical values of R1=10 kΩ and R2=10 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain (hFE) of 30 at -5 mA and -5 V, with a transition frequency of 250 MHz.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high reliability suitable for automotive applications through AEC-Q101 qualification.
• Offers compact SMD packaging for efficient space utilization in dense layouts.

Applications

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

Procurement Notes

Verify the specific suffix 'UAT106' against official ROHM documentation to confirm tape-and-reel packaging and exact resistor tolerances. Ensure compatibility with existing PCB footprints for the UMT3/SOT-323-3 package. Confirm RoHS compliance status for the target market regulations before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated 10kΩ/10kΩ bias resistors is required. It serves as a direct replacement for legacy parts like DTA114GUA where automotive-grade reliability is needed. Consider the -50V rating and -100mA current limit for load matching. Verify that the UMT3 package dimensions fit the mechanical constraints of the assembly.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from ROHM. It complements NPN counterparts such as the DTC114GUAT106 within the same family. The series is designed to replace discrete resistor-transistor combinations, offering consistent performance across temperature ranges and reducing board space requirements in modern electronic designs.

Replacement Considerations

DTA114GU3HZGT106 is listed as a similar level part with the same pinout and package. Verify if the HZG suffix indicates any functional differences or updated manufacturing specifications compared to the standard UAT variant before substitution.
