DTA023YMT2L

Overview

The DTA023YMT2L is a PNP digital transistor with built-in resistors manufactured by ROHM Semiconductor. It features an input resistance (R1) of 2.2 kΩ and an emitter-base resistance (R2) of 47 kΩ. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Key electrical parameters include a DC current gain (hFE) of at least 80 at IC = -5 mA and VCE = -10 V, and a transition frequency (fT) of 250 MHz. Power dissipation is rated at 150 mW. The component is housed in a VMT3 (SOT-723) surface-mount package.

Feature Summary

• Integrates bias resistors to simplify circuit design without external components
• Optimized for high-speed switching applications with a 250 MHz transition frequency
• Compact SMD footprint suitable for space-constrained layouts

Applications

• General-purpose switching circuits
• Interface driver stages
• Logic level translation buffers

Procurement Notes

Verify the specific suffix YMT2L against the official datasheet to confirm resistor values and polarity. Ensure the ordering code matches the required tape-and-reel quantity of 8000 units if bulk procurement is intended. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a PNP configuration with low input impedance is required. The 2.2 kΩ input resistor allows for direct interfacing with standard logic outputs. Verify that the -50 V rating meets the system's voltage requirements and that the 150 mW power dissipation is sufficient for the thermal environment.

Part Context

This part belongs to ROHM's DTA series of pre-biased transistors. These devices combine a single bipolar junction transistor with internal biasing resistors. The DTA023 variant specifically utilizes a 2.2 kΩ input resistor and 47 kΩ emitter resistor configuration, distinguishing it from other series members with different ratios.
