DTA124EMT2L

Overview

The DTA124EMT2L is a PNP digital transistor from ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes typical input resistance (R1) and emitter-base resistance (R2) values of 22 kOhms each, maintaining a resistor ratio of approximately 1. Key electrical parameters include a minimum DC current gain (hFE) of 56 at -5 V and -5 mA, a maximum operating frequency of 250 MHz, and power dissipation of 150 mW. It is housed in an SOT-723-3 surface-mount package.

Feature Summary

• Integrates bias resistors to eliminate external components for inverter circuits
• Optimized for automotive applications with AEC-Q101 qualification
• High-frequency operation capability up to 250 MHz

Applications

• Automotive inverter circuits
• Interface driver stages
• General-purpose switching applications requiring simplified biasing

Procurement Notes

Verify the specific suffix 'T2L' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and exact binning. Ensure the component meets AEC-Q101 automotive grade requirements if used in vehicle systems. Cross-reference the RoHS compliance status with the latest environmental declaration documents provided by ROHM Semiconductor before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with equal internal resistors (R1=R2=22kΩ) is required for space-constrained designs. The SOT-723 package offers a compact footprint suitable for high-density PCB layouts. Consider the -50 V rating and -100 mA current capacity to ensure adequate headroom for the intended load. Verify thermal management needs given the 150 mW power dissipation limit in the small outline package.
