DTA115EMFHAT2L

Overview

The DTA115EMFHAT2L is a PNP digital transistor from ROHM Semiconductor, featuring built-in bias resistors in an SOT-723 (VMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes two internal resistors, R1 and R2, both typically rated at 100 kΩ, configured as a potential divider type. Key electrical parameters include a minimum DC current gain (hFE) of 82 at -5 mA and -5 V, a power dissipation of 150 mW, and a maximum operating frequency of 250 MHz. It is qualified to AEC-Q101 automotive standards.

Feature Summary

• Integrates dual bias resistors (R1=R2=100kΩ) to simplify circuit design by eliminating external components.
• Automotive-grade reliability compliant with AEC-Q101 qualification standards for harsh environments.
• Compact SOT-723 package enables high-density mounting on printed circuit boards.

Applications

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

Procurement Notes

Verify the complete part number including the suffix T2L, which indicates the tape-and-reel packaging configuration. Confirm that the specific revision matches the required automotive grade specifications. Check for RoHS compliance status as indicated in the official documentation. Ensure the ordering quantity aligns with the standard reel size of 8000 units if full reels are required. Validate the manufacturer source directly with ROHM Semiconductor or authorized distributors.

Selection Notes

Select this component when a PNP digital transistor with equal bias resistors is required for automotive or industrial applications. The 100 kΩ resistor values are suitable for standard logic interface levels. Consider the SOT-723 package dimensions for space-constrained designs. Compare against complementary NPN types like the DTC115EMFHAT2L for push-pull configurations. Verify thermal performance requirements against the 150 mW power dissipation limit.

Part Context

This part belongs to the DTA115 series of digital transistors from ROHM Semiconductor. It is specifically designed for automotive applications, distinguishing it from standard commercial grades. The EMFH designation indicates the specific resistor ratio and package type within the broader product family. It serves as a replacement for discrete resistor-transistor combinations in switching circuits.

Replacement Considerations

Direct substitutes may include other ROHM PNP digital transistors with similar resistor ratios and packages, such as DTA115EMHZG. Cross-brand replacements require matching VCEO, IC, and hFE specifications. Verify pinout compatibility and thermal characteristics before substitution.
