DTA114YMFHAT2L

Overview

The DTA114YMFHAT2L is a PNP digital transistor manufactured by ROHM Semiconductor, designed for automotive applications. It features an integrated bias resistor network with R1 and R2 values of 10 kΩ each, eliminating the need for external input resistors. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -0.1 A. Key electrical specifications include a minimum DC current gain (hFE) ranging from 68 to higher thresholds depending on test conditions, and a power dissipation rating of 0.15 W. It is housed in a compact SOT-723 package suitable for surface mount technology.

Feature Summary

• Integrated bias resistor network simplifies circuit design by removing the requirement for external input resistors.
• Automotive-grade reliability compliant with AEC-Q101 standards for high-temperature operation.
• Compact SOT-723 package enables efficient space utilization in dense PCB layouts.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications in automotive electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel packaging quantities prior to ordering. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to prevent package damage during soldering processes.

Selection Notes

Select this component when a PNP digital transistor with equal internal resistors (R1=R2=10kΩ) is required for automotive environments. Compare hFE ranges and power dissipation limits against load requirements. Consider the SOT-723 footprint constraints relative to alternative packages like SOT-323 or SC-70 if space is limited.

Part Context

This part belongs to the DTA114 series of built-in resistor transistors. It serves as a complement to NPN variants such as the DTC114 series. The 'T2L' suffix typically denotes the taping packaging format for automated assembly. It is distinct from non-automotive grade parts lacking AEC-Q101 qualification.

Replacement Considerations

Direct substitutes must match the PNP polarity, SOT-723 package, and 10kΩ/10kΩ resistor ratio. Verify that any replacement meets AEC-Q101 automotive standards if used in vehicle systems. Check for equivalent hFE and voltage ratings to ensure functional compatibility without redesigning the surrounding circuitry.
