Overview
The DTA123YMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an input resistor (R1) of 2.2kΩ and an emitter-base resistor (R2) of 2.2kΩ, resulting in a typical resistance ratio of 4.5. Key electrical parameters include a minimum DC current gain (hFE) of 33 at -10mA and -5V, a transition frequency of 250MHz, and a power dissipation of 150mW. It is housed in the VMT3 (SOT-723) surface-mount package.
Feature Summary
- Integrates PNP bipolar transistor with internal biasing resistors for simplified switching applications
- Eliminates external input resistors, reducing component count and board space requirements
- Designed for high-speed switching with a transition frequency up to 250 MHz
Applications
- General-purpose signal switching circuits
- Interface driving for logic level translation
- Inverter circuits requiring compact footprint
Procurement Notes
Verify the specific suffix 'T2L' against the official ROHM datasheet to confirm tape-and-reel packaging details and marking codes. Ensure compatibility with RoHS directives if required by the target application. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as manufacturing status may vary.
Selection Notes
Select this component when a PNP digital transistor with a 2.2kΩ input resistor is required. The VMT3 package suits applications with strict space constraints. Verify that the -50V rating and -100mA current capacity meet the load requirements. Consider thermal dissipation limits within the SOT-723 package for high-duty-cycle operations.
Part Context
This part belongs to the DTA123YE series of digital transistors from ROHM. It shares functional similarities with other members like DTA123EMT2L but differs in specific resistor values and package options. The DTA123YMT2L specifically utilizes the VMT3 package, distinguishing it from through-hole or larger surface-mount variants in the broader family.
Replacement Considerations
Direct substitutes include DTA123EMT2L and DTA123JMT2L, provided the resistor ratios and hFE characteristics align with the design requirements. Verify pinout compatibility and package dimensions before substitution.
